Hot Mirrors

Our Hot Mirrors are designed to manage heat by reflecting unwanted infrared (IR) radiation while allowing visible light to pass through brightly and accurately. This is essential for protecting sensitive components like CCD/CMOS sensors, projection optics, and high-brightness LED engines from thermal damage or drift. In entertainment lighting, they play a vital role in extending the life of lamps and preventing colored gels or gobos from wilting under intense heat.

The durable reflective IR coating is applied to your choice of high-quality glass, capable of withstanding temperatures up to 450°C. We can machine parts into any geometry you need, from tiny 5 mm windows to large 450 mm protective plates. For maximum performance, we can add an anti-reflective coating to the visible side, achieving over 98% light transmission. As with all our optics, every piece passes MIL-M-13508C environmental tests for guaranteed reliability.
