Diffuse Reflection Standard (Standard White Board)


Diffuse Reflection Standard (Standard White Board), PTFE polytetrafluoroethylene, 350-2000nm, reflectivity 97%, size Φ20mm/Φ30mm/Φ100mm

The standard whiteboard is made of PTFE material, and its surface is a Lambertian diffuse reflection surface. Reflected light in any direction obeys the cosine law. The outer casing material is anodized aluminum, which is waterproof and stable, and can withstand deep UV applications. The whiteboard is mainly used for optical calibration measurements, such as light source, color, spectral analysis, etc. It is one of the important accessories of the optical integrating sphere. The diameter of the reflective surface of the standard whiteboard is optional from Φ20mm to 100mm. The reflective material is enclosed in a small box and has a threaded lid for protection.
