Labsphere’s Permaflect II durable diffuse reflectance targets, ranging from 5% to 94% reflectance values, enable users to characterize and calibrate their products over a broad range of ambient conditions. Permaflect II is the newest series of diffuse reflectance coatings and targets from Labsphere, supplementing the Spectralon® and Spectraflect® product offerings. Permaflect II targets are ideal for use in the UV-VIS and NIR from 250 to 2500 nm. They are the preferred alternative in applications where traditional coatings, paints, and paper cannot meet the durability and repeatability requirements. Specific applications where Permaflect II targets are recommended include: Time of Flight, Ground Truth, Imager Calibration, Sensor/Source Compensation, Integrating Sphere Coating, Integrating Cavity Coating, and Medical Diagnostic Instrumentation.
