Optical Raise Color Temperature Filter Glass

Optical Raise Color Temperature Filter Glass Optical Raise Color Temperature Filter Glass is a specific class of optical filter designed to modify the spectral output of a light source by making it appear "cooler" or more blue. This process is known as increasing the correlated color temperature (CCT), measured in Kelvin (K). Specification:   1. Fundamental Principle: What Does "Raise Color Temperature" Mean?   · Color Temperature: This is a scale that describes the color characteristics of light. A low color temperature (e.g., 2800K) appears warm and yellow/red (like a sunset or a tungsten bulb). A high color temperature (e.g., 6500K) appears cool and blue (like an overcast sky or daylight). · The Goal: The sole purpose of this glass is to absorb a significant portion of the longer wavelengths (the yellow, red, and infrared parts) of the incoming light spectrum. By removing these warmer colors, the proportion of shorter wavelengths (blue light) in the transmitted light becomes…
