SphereOptics offers a range of diffuse, white, greyscale and multi-step contrast reflectance targets which are used to test and calibrate remote sensing instruments, spectroradiometers, image sensors and the LIDAR and ADAS sensors used in autonomous vehicle technology. Compared to glossy surfaces, diffuse reflectance targets provide for stable, consistent reflectance regardless of instrument alignment or illumination and viewing geometries. SphereOptics’ targets for the UV-VIS-NIR spectral range are offered using proprietary Zenith Polymer® or using Labsphere’s Spectralon® diffuse reflectance material. Zenith Polymer® and Spectralon® are characterised by stable, Lambertian (diffuse) reflectance. For the infrared band, (2.5-15µm) we offer targets based upon Labsphere’s Infragold® diffuse reflectance coating. If you care about portability, Zenith Lite™ PTFE targets are lightweight and more easily transported and deployed in field measurements. Last but not least, Labsphere’s Permaflect® targets provide the ultimate in environmental stability and durability and are perfect for testing time-of-flight instrumentation (LIDAR systems).
