SphereOptics provides a large spectrum of Zenith Polymer® diffusers. Those diffusers are available in several different sizes, thicknesses (those define the percentage of transmission) and reflection characteristics. It is possible to attach high level gluing foil on a Zenith Polymer diffuser, which allows an easy processing.
Zenith Polymer® Greyscale Diffuser
Lambertian reflectance sheets
To realise optical and process stability, often Zenith Polymer® greyscale diffuser sheets are used as an optical baseline reference. To enable the customer to adapt the optical standard to his or her needs, we offer the greyscale Zenith Polymer® as 1 mm thick sheets, optionally with the proper gluing agent applied, so engineers and quality control personnel can fit the standard to their needs.
Zenith Polymer® White Diffuser
Lambertian transmission sheets
Thin section Zenith Polymer® sheets are used as cosine diffusers minimise angular dependency of the light reaching a photodetector or to create more even illumination from a light source. With a constant, lambertian throughput over the entire wavelength range of 250 nm to 2450 nm, the Zenith Polymer® diffuser finds application in a variety of light scattering measurements and calibration setups.
