(PM)VOA Variable Optical Attenuators

mini Liquid Cooling Evaluation Kit; Cooling Capacity 450 W @+25°C; Power Supply 24 VDC Key Features: Up to 450 W Cooling Capacity Ideal for Compact Cooling of Lasers or Bio Reagents Ideal for Mobile Cooling Applications Compressor Speed Control for Ease of Temperature Control Low Vibration, Low Noise Lightweight, Compact Easy to Integrate Kit to Interface With OEM Water Circuit and Electronics Control Components Carefully Designed to Match Each Other The mLC-C-450-24-KIT is a sealed vapor compression circuit with a speed controlled miniature rotary BLDC compressor. The evaporator is a brazed plate heat exchanger, the interface to the customer liquid coolant circuit.  The mLC-C-450-24-KIT comes with the separate 24 VDC inverter board. The compressor speed can be set from the upper control system by frequency or analog signal. The condenser is an aluminum finned copper tube heat exchanger coil and must be cooled by forced convection, i.e. a 120x120 mm fan or equivalent. The heat exchanger stainless steel plates are nickel brazed suitable for a variety of coolant fluids, such as water, DI water and glycol-water mixtures. The plate heat exchanger has male R ¼” connectors for the customer to connect its water circuit.

Blocking, Pigtail Style; Fiber Type SM, MM, PM; 350 to 2050 nm; Connector Type NTT-FC/PC, ST, SC, LC/PC, other; Attenuation up to 80 dB OZ Optics’ BB-100/400/500/700-11 series of compact PC board mountable blocking pigtail style variable attenuators with low backreflection are designed to meet Telcordia standards. These attenuators can be used for 1300 nm and 1550 nm as well as for C, L and S bands, with minimal changes in the insertion loss. Mounting holes provide easy attachment to PC boards and patch panels. The mounting hole patterns and attenuator sizes can be modified to meet customer requirements The attenuators consist of two collimating lenses, prealigned for optimum coupling efficiency. A threaded radial screw is used to block the collimated beam between the two lenses. Because the attenuator works by directly blocking the beam, it is polarization insensitive. A seal cap is used to seal the junction against temperature and humidity effects. The attenuator can even withstand immersion in water for extended periods of time. Variable attenuators are offered with single mode, multi mode, or polarization maintaining fibers. Key Features: Rugged and Compact Size Wide Wavelength Range Single Mode, Multi Mode and Polarization Maintaining Fiber Versions Low PDL and Wavelength Dependency High Power Handling Wide Attenuation Range Low Backreflection Designed to Meet Telcordia Requirements Applications: Optical Power Equalization and Power Control for WDMs and Multi-channel Optically Amplified Networks; Telecommunications; CATV; LAN; Test and Measurement; Receiver Padding; Optical Sensors

Four wavelengths: 532 nm, 555 nm, 579 nm, 606 nm; pulse-by-pulse switchable with 2 kHz; Pulse Energy 20 µJ; Pulse Length <5 ns The diode-pumped solid-state laser TETRA emits very short laser pulses (< 5 ns) of high energy (up to 20 µJ) with four wavelengths in the visible range, which are particularly suitable for multispectral photoacoustic imaging. Using sophisticated technology, the TETRA laser can switch from pulse to pulse between these four wavelengths with a very high pulse repetition frequency of 2 kHz. Utilizing the Raman effect and the light of a 532 nm pump laser, the TETRA laser additionally generates the wavelengths 555 nm, 579 nm and 606 nm. A tunable optical filter separates the four wavelengths and routes one wavelength at a time to the optical output of the unit at a switching frequency of up to 2 kHz. This makes TETRA about ten times faster than tunable lasers based on OPOs (Optical Parametric Oscillators) – typical frequencies of such OPO systems range from 100 Hz to 200 Hz – while also being considerably more cost-effective. The wavelengths emitted by TETRA are well matched to the absorption curves of many blood components, making the laser particularly suitable for photoacoustic tomography in biomedicine. We have equipped TETRA with a number of features to meet the requirements of medical safety standards for use in clinical environments. For instance a fast, fault-tolerant shutter at the laser output interrupts the beam in the event of a fault in the shortest possible time in order to avoid any hazards to a patient.
