TOWER OPTICAL: Cold Mirror MC45-50.8
Description
Hot Mirrors are used in applications when there is the requirement to separate visible light from heat. The hot mirror accomplishes this by reflecting the heat. The use of Borosilicate type glass allows operation in high temperatures. Operation at an AOI of 0º is preferred. The most common wavelength range for an average transmission of 85% through the hot mirror is 420 - 700nm. The reflective range for the hot mirror for R>95% is 800 - 1000nm. Additionally, R>50% from 735 - 1080nm.
Cold Mirrors are used where the requirements are to reflect visible light and remove the heat by transmission. Operation at an AOI of 45º is preferred. The most common wavelength range for transmission through the cold mirror is 800 - 1200nm. The average transmission range is T>85%. Additionally, R>95% for 400 - 700nm.
