Hot and Cold Mirrors 19 561-740-2525 • Fax 561-740-2518 sales@TowerOptical.com • www.TowerOptical.com Cage Code: 1N2U3 SDVO-SB ITAR Compliant HotMirrors 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 0° is preferred. The most common wavelength range for an average transmission of 85% through the hot mirror is 420 – 700 nm. The reflective range for the hot mirror for R>95% is 800–1000 nm. Additionally, R>50% from 735 – 1080 nm. Cold Mirrors are used where the requirements are to reflect visible light and remove the heat by transmission. Operation at an AOI of 45° is preferred. The most common wavelength range for transmission through the cold mirror is 800–1200 nm. The averagetransmission range is T>85%. Additionally, R>95%for 400 - 700 nm.
