Reference Panels – White Reference

SphereOptics offers the classic style of PTFE full material targets as well as a reflectance coating on the basis of barium sulfate for diffuse and nearly 100 % reflection. Alternatively the SphereOptics Team has developed the next generation of large area targets. Our new Zenith Lite targets, apply a unique technique, which laminates diffuse material onto a lightweight sandwich backing. The significant advantages are less weight, weather resistance as well as much lower costs. Generally all reflectance values of 5, 20, 50, 90 und 95% and standard sizes of 200x200mm, 500x500mm and 1000mmx1000mm are available from stock. Customized products are also available.
