Hot and Cold Mirrors
Hot and Cold Mirrors is applications IR-Filters for CCD-Chips Projectors Lighting Systems Detector Trimmers Sensors.
Hot Mirrors Reflect IR
Cold Mirrors Reflect Visible Light
0° and 45° AOI Available
Hot mirrors transmit visible light and reflect IR, allowing them to protect heat-sensitive elements by reflecting IR energy. In contrast, cold mirrors reflect visible light and transmit IR. They are ideal for projection applications and for use as low- and high-pass filters.
