Spectralon® Diffuse Reflectance Targets

Near Lambertian; 350-1000 nm; Grey Scale Level 5-94%; Uniformity ±1%, ±1.5%, ±2%; Target Size 0.5x0.5-1.2x2.4 m Labsphere’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) Tailorable Targets Sizes: 0.5 x 0.5, 1.0 x 1.0, 1.5 x 1.5, 1.2 x 2.4 m Target Sizes Are Ideal for the Operating Distance Reflectance Levels in NIR Laser Wavelength 905 to 940 and 1550 nm Grey 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 nm Near Lambertian Diffuse Reflectance Factor for Incident Angle Independence Durable and Robust for Production and Field Use Easy to Clean LiDAR Test Kit Accommodates Mounting of the Frameless Targets Applications: 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 Factor

Highly Lambertian; 250-2500 nm; Reflectance Factor 2-99%; Reflective Area Ø 31.75, 50.80 mm; Dimensions Ø38.1x14.0, Ø60.45x15.2 mm Labsphere’s Spectralon® diffuse reflectance standards can offer the highest diffuse reflectance values of any known substance. These durable, chemically inert standards can have typical reflectance values ranging from 2% to 99% and are spectrally flat over the UV-VIS-NIR spectrum. All Spectralon materials are optically flat to ±4% over the range of 250 to 2500 nm and ±1% over the photopic region of the spectrum. Spectralon diffuse reflectance standards are highly Lambertian, with Spectralon SRM-99 reflectance material being the most Lambertian reflector available for use over the wavelength range from 250 to 2500 nm. All reflectance calibration tests are performed in the Reflectance Spectroscopy Laboratory at Labsphere. The standards used in these tests are directly traceable to the National Institute of Standards and Technology (NIST). Spectralon diffuse reflectance standards are available individually and in sets, consisting of a diffuse white standard and a selection of diffuse gray standards. Each standard is supplied with complete diffuse reflectance data from 250 to 2500 nm, every 50 nm. All standards are housed in a durable delrin holder with a protective cover. Diffuse reflectance standards are available in sets of four or eight standards in either 31.75 or 50.80 mm diameters. A set of four standards includes one each of the following reflectance values: 99%, 75%, 50% and 2%. A set of eight standards includes one each of the following reflectance values: 99%, 80%, 60%, 40%, 20%, 10%, 5% and 2%. Diffuse reflectance standards are also available individually (31.75 or 50.80 mm diameter, reflectance values 99%, 80%, 75%, 60%, 50%, 40%, 25%, 20%, 10%, 5% and 2%) or even on custom order with reflectance properties to meet your specific needs. Please contact the AMS Technologies reflectance standard experts to discuss your customized diffuse reflectance standard solution.
