Custom Optical Skylight Filter Glass TB1 TB2

Custom Optical Skylight Filter Glass TB1 TB2   Optical Skylight Filter Glass TB1 and TB2 are classic types of optical filter glass primarily designed to simulate the spectral properties of natural skylight. They belong to a category of "conversion filters" used to correct the color temperature of light sources to match that of a standard overcast sky. Specification: Key Characteristics and Function   1. Primary Purpose: Daylight Conversion and Color Correction The fundamental role of Skylight filters like TB1 and TB2 is to convert a warmer, reddish light source into a cooler, bluish light that resembles average daylight (specifically, the light from an overcast sky, which has a high correlated color temperature around 6770 K).    · They achieve this by selectively absorbing a portion of the longer wavelengths in the visible spectrum, specifically the yellow and red light.    · This absorption process effectively raises the color temperature of the transmitted light, making it "coo…
