Zenith polymer standard diffuse reflector

It has a nearly flat reflectance in the wavelength range of 250 to 2450 nm and reflection characteristics that approximate ideal Lambertian reflection, making it optimal as a standard reflector.

SphereOptics' standard diffuse reflector is made from a unique material called Zenith Polymer. It is durable against heat, humidity, and high-output light sources, and has a nearly flat reflectance in the wavelength range of 250 to 2450 nm, with reflection characteristics that approximate ideal Lambertian reflection, making it optimal as a standard reflector. It is available with reflectance values of 99%, 80%, 60%, 50%, 25%, 10%, 5%, and 2.5%, in two sizes: Φ50mm and Φ30mm. ■ Features - Diffuse reflectance from 2.5% to 99% - Nearly flat reflectance in the wavelength range of 250 to 2450 nm - Approximates ideal Lambertian reflection - Tolerance of reflectance values by batch ±3% - Laser damage threshold: 8 J/cm² @ pulse laser - Certified calibration using PTB and NIST traceable PerkinElmer Lambda 950 - Non-polar, insulating, hydrophobic - Chemically inert (except reacts with organic lithium and sodium compounds) - Operating temperature range: -50 to 250 ℃ - Operating humidity range: 5 to 95%
