An optical sheet with optical properties that approximate a flat reflectance over the wavelength range of 250 to 2450 nm and ideal Lambertian transmission/reflection.
The Zenith Polymer Lambertian Diffusing Transmission/Reflection Sheet from SphereOptics has spectral characteristics that approximate ideal Lambertian transmission or reflection over a wide spectral range of 250 to 2450 nm.
It is available in a lineup of transmission rates of 50%, 25%, 16%, 8%, and 4%, as well as reflection rates of 80%, 50%, 30%, 20%, 10%, and 5%, in three size options: 200x200 mm, 500x500 mm, and 1000x1000 mm.
