Horizontal PER <20:1; Beam Diameter 20, 38, 40 mm; Lens 25,75,150 mm, Collimating; Min. Layer Thickness 10-50 µm; Single High-flex Umbilical Luna’s T-Ray® 5000 measurement system is one of the fastest terahertz systems available on the market. Luna’s broad range of T-Gauge® sensor heads and gauges are paired with the T-Ray® 5000 Intelligent Terahertz Control Unit to create a complete system. Transmitter and receiver are securely mounted inside the online sensor head’s sealed metal housing. The umbilical for the transceiver, containing the electrical and optical connections, is constructed with high flex rated electrical cable to allow for continuous scanning. When connected to a T-Ray® 5000 Control Unit, the online sensor heads will provide excellent waveform response, capable of providing detailed reflection measurement of layered surfaces or products. The T-Gauge® HXC50yn is a high-performance online sensor head with full transceiver functionality and takes the robustness of the T-Ray® 5000 terahertz system to a new level with the ability to operate in industrial environments. Reflection measurement of thickness, multi-layer thickness, and basis weight are easily acquired. A variety of lenses are available to adjust the measurement spot size and working distance. The “y” and “n” in the model number correspond to the focal length of the lens, and the type of terahertz transmitter, respectively – “y” = 4 for 75 mm lens and 5 for 150mm lens, “n” = 1 for a type 1 transmitter and 2 for a type 2 transmitter. The T-Gauge® HXC51yn online sensor head adds functionality to the standard online sensor head with a virtual reference surface (VRS). Reflection measurement of thickness, multi-layer thickness, basis weight, and density are easily acquired. The VRS enables non-contact, calibration-less caliper thickness measurement as well as basis weight and density without reducing the open separation between the sensor and the product. The T-Gauge® HXP51y2 online EPG sensor head allows measurement of thinner layers than the standard HXC50yn online sensor head. With higher bandwidth and higher signal to noise, the EPG opens new applications to terahertz process control. Coatings on metal or composite substrates and free standing films can be measured down to 10 µm (0.5 mil). The T-Gauge® HSC50yn compact industrial sensor is designed for industrial applications that require a smaller footprint, a lighter weight or two output beams. These capabilities are met by the HSC50yn, which capitalizes on the new single fiber lighter weight umbilical, and a more compact design, to allow robot mounting. With proper attention to the configuration, it can be used to inspect two points on the same object. In the case of small diameter tubing, this can even be used to measure four orthogonal points at the same time. The T-Gauge® SCS500n explosion-proof thickness measurement system takes the robustness of the T-Ray® 5000 to a new level with the ability to operate in flammable atmospheres, such as paint booths or coating facilities. Designed to be robot mountable and intrinsically safe, the T-Gauge® SCS500n Online Sensor Solution CID1 SCS500n is optimized for use in spray booth applications but can be used in other applications as well. The working distance of the sensor head is fixed at 115 mm, but other working distances may be available upon request. The T-Ray® 5000 LSG500n line scan gauge (LSG) provides a handheld solution for high-speed scanning of a line 50 mm or 75mm in length. The line scan image is displayed on the screen of the handheld tool and can be analyzed by dedicated software for specific applications. Current software solutions can provide layer thickness measurements, detection of voids, or alignment of body panels with measurement of the vertical and horizontal offset between them. The T-Ray® 5000 SPG500n single point thickness measurement gauge allows direct measurement of multiple layer objects with the press of a button. The modular nature of the measurement tool allows either straight-on or right-angle measurement tips. By using pulse time-of-flight (ToF) to make its measurements, the SPG500n has greater insensitivity to environmental and material variations that can lead to calibration inaccuracies, as well as operator inconsistencies. The measurement is fundamentally non-contact, but for hand-held use, a measurement tip is used to aid the user in positioning the object at the focus of the THz beam.

Active Area Diameter 0.18 mm; Max. Dark Count Rate 25-2,500 c/s; Photon Detection Efficiency 60%-75%; Max. Count Rate 40 M c/s; Dead Time 22, 50 ns; Pulse Width 10, 30 nsExcelitas’ SPCM single photon counting modules are self-contained modules that meet the low-light-level detection demands of confocal microscopy, fluorescence, luminescence, and TCSPC, particle sizing and quantum communications.SPCM modules use a unique silicon avalanche photodiode (SLiK) with a 180 µm diameter circular active area, achieving peak photon detection efficiency greater than 65% to even 75% (depending on model) with unmatched uniformity over the full active area.The photodiode is both thermoelectrically cooled and temperature controlled, ensuring stabilized performance despite ambient temperature changes. Operating temperature range has been increased and the module will function with case temperatures between +5 ˚C and +70 ˚C.SPCM single photon counting modules are ideal for laboratory and OEM use and offer market-leading photon detection efficiency (PDE), low after-pulsing, high linear dynamic range, and low dark counts.Excelitas' newly enhanced SPCM-AQRH single photon counting module detects single photons over the wavelength range of 400 nm to 1064 nm with performance parameters superior to other solid state or vacuum-tube based photon counters.The SPCM-AQRH achieves >70% peak photon detection efficiency at 650 nm. A TTL-level pulse is generated for each photon detected and the signal is available at the BNC connector at the rear of the module. The module comes as standard with a free-space window to the APD, with FC fiber adapter, C-mount or tube cage mount bracket/adapter options.Recent electronic circuit enhancements have reduced the minimum dead time to less than 25 ns, thereby increasing linearity and improving the dynamic range of the module. Timing resolution of the module was also improved significantly. The SPCM-AQRH has internal protection circuitry that protects the avalanche photodiode and the module electronics from damage due to accidental overload from exposure to ambient lighting.The Excelitas SPCM-AQRH-WX-TR is a single photon counting module of the latest product generation, specifically selected and performance-optimized for timing resolution. This family of –TR modules is designed to support applications in time-correlated single photon counting (TCSPC), fluorescence lifetime measurements and fluorescence lifetime imaging microscopy (FLIM).The SPCM-AQRH-WX-TR uses a specially selected SLiK silicon avalanche photodiode with timing resolution better than 250 ps while maintaining peak photon detection efficiency (PDE) of more than 75% at 650 nm over a 180 µm diameter active area. While some performance parameters, in particular afterpulse probability, are traded off against the optimized timing performance, other performance parameters of the standard SPCM-AQRH, such as outstanding uniformity, overload protection, temperature stability and linearity, are still maintained by this timing-optimized module.The Excelitas SPCM-NIR is a single photon counting module specifically selected and performance-optimized for the near infrared wavelength spectrum. This NIR spectrum enhanced device is designed to support long range LiDAR, quantum communication and microscopy, as well as many other applications.The SPCM-NIR uses a specially selected SLiK silicon avalanche photodiode with peak single photon detection efficiency typically better than 73%. This module achieves enhanced red and NIR sensitivity while maintaining such other performance parameters of the standard SPCM-AQRH, such as outstanding uniformity, overload protection, temperature stability and linearity.The SPCM-AQ4C is a four-channel photon counting module capable of detecting single photons of light over the wavelength range from 400 nm to 1060 nm. Each channel is independent from the others.The SPCM-AQ4C uses a unique silicon avalanche photodiode (SLiK) with a peak photon detection efficiency exceeding 60% at 650 nm and an improved circuit with a peak count rate >4M c/s for short bursts of time on all four channels and a count rate of 1.5 M c/s for continuous operation. There is a "dead time" of 50 ns between pulses.The module requires +2 V, +5 V, and +30 V power supplies. The output of each channel – a TTL pulse that is 4.5 V high (into a 50 Ω load) and 25 ns wide – is available at the card edge behind the circuit board. Each TTL pulse corresponds to a detected photon. All input and output signals are available at the card connector.Applications: Particle Sizing & Characterization; Confocal Microscopy; Photon Correlation Spectroscopy; Quantum Cryptography; Astronomical Observation; Optical Range Finding; Adaptive Optics; Ultra-sensitive Fluorescence; Flow Cytometry; Wind LiDAR Part Number Photo Sensitive Diameter Maximum Dark Count Rate Photon Detection Efficiency @ 650 nm Max.

Polarization Sensitive & Insensitive Versions; 1040 nm to 1090 nm; Isolation ≥35 dB; Power Handling ≤80 W; 48 mm x 48 mm x 133 mm The FO(P)I-00 series of free space isolators are featuring options to allow the customer to mount their own fiber pigtailed collimator or beam expander. The OZ Optics tilt adjustment technique gives customers the ability to perform the optical alignment themselves.Isolators are optical devices that allow light to be transmitted in one direction only. They block the source from reflected light, thus preventing any feedback problems, such as frequency instability, relaxation oscillations, amplified stimulated emissions, or optical damage – very critical with the recent dramatic increase in laser output powers, especially in the 1030 to 1090nm wavelength range. To meet this demand OZ Optics has developed a line of high power handling isolators, capable of peak isolation levels of 30 dB to 50 dB for 1030 nm to 1090 nm, depending on the input beam size (with typical beam diameters of 0.4mm to 1.1mm). The isolators come with built-in windows to prevent dust contamination of internal isolator optics. These protection windows are easily removed and replaced by the user. Custom smaller packages can be made for OEM applications – contact us for more details. Key Features: Operating Wavelength Range: 60 nm Power Handling: Up to 80 W Isolation: Up to 50 dB Low Insertion & Polarization-dependent Losses Excellent Beam Quality Removable Protective Windows RoHS compliant Applications: Protection of high power lasers from reflections during a) laser marking and engraving; b) laser cutting and etching of metal surfaces with high reflectance such as Al, Cu, Au or Ag; c) micro machining and trimming

Multi Mode, Square Core; 190 to 2400 nm; Core Size 100 to 1000 µm; Coating Acrylate, Nylon, Polyimide; Numerical Aperture 0.22Fiberguide’s Anhydroguide™ (ASQR) and Superguide™ (SSQR) series of square silica core, doped round cladding multi mode optical fibers excel in specific applications where traditional circular core fibers with Gaussian outputs are not ideal. The uniform “top hat” intensity profile these fibers provide are the desired output profile when performing tasks such as welding, photolithography, and spectroscopy. Square core fibers with round claddings are also excellent candidates for use in the laser diode industry, where the square shape enables a more ideal coupling match with the diode source. Fiberguide offers pure silica square core fibers with a fluorine doped cladding (0.22 NA) in a wide range of core diameters from 100 μm to 1000 μm. While the ASQR series features a low hydroxyl ion concentration (low OH) and works in the visible to IR range, SSQR variants with high hydroxyl ion concentration are suitable for the UV to visible range. Options include Acrylate, Polyimide and Nylon coatings as well as anti-reflective coatings like standard thin film coatings or RARe Motheye nano-surfacing. This anti-reflective technology enhances fiber transmission performance and significantly increases the damage threshold for your application over a large wavelength range.
