Near Lambertian; 350-1000 nm; Grey Scale Level 5-94%; Uniformity ±1%, ±1.5%, ±2%; Target Size 0.5x0.5-1.2x2.4 mLabsphere’s Permaflect® large-area, grey and white, reference diffuse reflectance targets are ideal for accurately assessing short-range and long-range sensitivity over the dynamic range of LiDAR systems.For imaging applications your grey target solution must work for a wide variety of lighting environments and still maintain its appearance. Most importantly it has to have uniform spectral response. It also must be thermally and physically durable, UV light stable, thermally color stable, no gloss, no polarization and no fluorescence.If your grey target solutions do not meet these requirements, you need Permaflect diffuse reflectance targets. Permaflect targets are available for individual purchase in three sizes: 0.5 x 0.5, 1.0 x 1.0, 1.5 x 1.5 or 1.2 x 2.4 m, unframed and with or without mounting. Available reflectance factors are 5%, 10%, 18%, 50%, 80% and 94%.Permaflect diffuse reflectance targets are also available in Labsphere's LiDAR Test Target Kits, including three reflectance levels; 10%, 50% and 80%, a robust case that holds all three Permaflect targets for storage and transport, and spectral reflectance and uniformity test reports. The kits come in a choice of three target sizes; 0.5 x 0.5, 1.0 x 1.0 and 1.5 x 1.5 m.Key Features:Lightweight: 1.5 kg (0.5 x 0.5 m) to 18 kg (1.2 x 2.4 m)TailorableTargets Sizes: 0.5 x 0.5, 1.0 x 1.0, 1.5 x 1.5, 1.2 x 2.4 mTarget Sizes Are Ideal for the Operating DistanceReflectance Levels in NIR Laser Wavelength 905 to 940 and 1550 nmGrey Scale Levels: 5%, 10%, 18%, 50%, 80%, 94%Variance From Average: ±1%, ±1.5%, +3%/-0%Uniform Reflectance Over the Entire Reflecting Surface – Uniformity: ±1%, ±1.5%, ±2%Typical Flatness: 0% to 8% Peak-to-Peak From 350 to 950 nmNear Lambertian Diffuse Reflectance Factor for Incident Angle IndependenceDurable and Robust for Production and Field UseEasy to CleanLiDAR Test Kit Accommodates Mounting of the Frameless TargetsApplications: LiDAR; Time of Flight; Ground Truth; Imager Calibration; Sensor/Source Compensation; Remote Sensing; Coatings & Materials; Airborne Calibration; Automotive Sensor Calibration; Spectral Radiance; Spectroradiometer Calibration; Reflectance FactorPlease note that Labsphere products are available from us only in Denmark, Finland, Iceland, Italy, Norway, and Sweden.

Fused Silica, CaF2; 415-1700 nm, Customer Specified; Finesse 56-~100, Customer Specified; FSR 15-60 GHz, 0.5-2/cm, Customer Specified; Thickness 1.68-6.74 mm, Customer Specified; AR and HR Coating; 22.0x24.0, Customer Specified; Clear Aperture 18x18 mm, Customer Specified LightMachinery’s OP-6721/OP-7553 series of VIPA (Virtually Imaged Phase Array) etalons are manufactured from Fused Silica (OP-6721) or Calcium Fluoride (OP-7553), allowing operation further into the infrared, IR) using the company’s patented fluid jet polishing (FJP) technology – allowing the adjustment of the etalon’s shape and flatness to within a few nanometers. Catalog series OP-6721 VIPA etalons are available with dimensions of 22.0 x 24.0 mm and 18 x 18 mm aperture. Free spectral range (FSR) values are 15 GHz (0.5/cm), 30 GHz (1/cm) and 60 GHz (2/cm), each available with nine different finesse values from 56 to 100, resulting in nine different wavelength ranges from 415 to 1700 nm. Wavelength range, thickness, finesse, FSR and other design details of OP-6721 and OP-7553 series VIPAs are also available based on customer requirements. For the OP-6271 series, a dedicated protective aluminium mount is available that enables mounting the VIPA in a standard 50.8 mm (2”) diameter optic holder – its price includes cementing of the VIPA to the mount at the supplier. A VIPA (Virtually Imaged Phase Array) is a special type of Fabry-Perot etalon with a built-in transmission window so the beam can sneak in past the first reflector and effectively commence the multiple reflections and constructive and destructive interference from inside the etalon. By changing the first reflector to a full 100% high reflector, the beam can only exit in transmission, this effectively creates an etalon with ~100% transmission. VIPAs are made with three distinct coatings, carefully selected to match the wavelength range of interest: One surface of a VIPA has an anti-reflection coated section adjacent to a high reflector. The opposite surface is coated with a partially transmitting mirror. Light is introduced into the VIPA at a small angle on the AR coated area. The VIPA is tilted so that the portion reflected from the partial reflector is fully incident on the high reflectance zone of the input surface. A single input beam is converted to a series of parallel output beams of gradually decreasing intensity. These beams will constructively interfere at an angle that depends on the wavelength. Placing a lens between the VIPA and an array detector (CCD or similar) allows recording of a spectrum of the input light. Each subsequent beam has a precise increase in phase and fixed lateral displacement, hence “phase array”. LightMachinery is the world leader in high-accuracy VIPA fabrication, and VIPAs are at the core of many of LightMachinery’s spectrometers. Several parameters define the performance of a VIPA. The first is its optical thickness (OPD) – the free spectral range (FSR) is approximately c/OPD. Analogous to a regular etalon, the angular dispersion of the VIPA output will repeat every time the input frequency (or wavelength) increases by 1 FSR. The second important parameter is the reflectance of the output mirror. In principle, a higher reflectance mirror will increase the resolving power of the VIPA. Light Machinery has optimized the partial reflectivity for each wavelength range to maximize finesse; finesse greater than 100 has been achieved for VIS/NIR applications. In other words, it will be possible to distinguish wavelengths separated by 1/100th of the FSR. The third important parameter is the internal angle of the light traveling through the VIPA. Smaller angles increase the angular dispersion, and a narrower transition between the antireflection coating and the high reflector enables a smaller angle. LightMachinery’s VIPAs have a transition width of only 2 to 3 µm, which enables operation of the VIPA at a very small angle. This reduction in angle improves resolution and contrast compared to what was previously possible. Sometimes you need something special – if you are looking for a customized VIPA etalon that exactly meets your specific requirements (e.g. different substrate materials like Silicon, etc.), please get in touch with the AMS Technologies etalon experts. Our supplier LightMachinery is extremely experienced with specifying, designing and manufacturing custom etalons using the company’s patented fluid jet polishing (FJP) technology. We are looking forward to discussing your customized etalon solution! Fluid jet polishing (FJP) systems use a fine stream of slurry to accurately remove nanometers of material from an optical surface. Many years of refining this computer controlled polishing technology have enabled LightMachinery to use FJP for the adjustment of the shape and flatness of optical components such as etalon mirrors to within a few nanometers as well as the production of very thin components such as wafers and thin etalons that are impossible to accurately polish using conventional technology.

Inside Diameter 15 to 450 µm; Outside Diameter 90 to 673 µm; Coating Polyimide; Temperature Range -190 to +350 °C; Tensile Strength >600 kpsi Fiberguide’s fused silica capillary tubing is used for micro-fluidics applications and in gas chromatography (GC) separation columns. These capillaries are coated with polyimide for mechanical stability and versatile uses. With inert surfaces and high purity, Fiberguide’s capillary tubing solutions provide a very high phase stability, while their peak mechanical stability leads to greater yield and more cost-efficient tubing. Based on the great flexibility combined with high tensile strength (>600 kpsi), these capillary tubing solutions are pressure resistant to 4,500 psi and allow very small radii during coiling with no kinking. They are impervious to chemicals, allowing usage in harsh environments. A wide range of internal and external diameters with tight tolerances allows users to select a capillary tubing solution that best suits their flow rate requirements. All capillaries can be easily cleaved or cut, allowing to adjust exactly the column length needed for interfacing. While the mirror smooth inner surface provides stable laminar flow profiles and good adherence, the capillary tubing solutions’ Polyimide coating is very durable and abrasion resistant.
