延伸型熱反射鏡

延伸型熱反射鏡經過精心設計，可減少光學系統中的熱量，同時不會導致系統的可見光輸出受損。典型熱反射鏡的反射範圍是750nm至大約1250nm，而延伸型熱反射鏡將反射範圍延伸到大約1750nm，從而進一步減少熱量。

Hot mirrors are crucial in many projection and illumination systems where high levels of heat can quickly damage sensitive components. Hot mirrors are specially coated to transmit visible light while reflecting the NIR, a major attributor to heat generation. By using a hot mirror, heat levels are limited with minimum impact on the overall system performance.
