Andover Heat Control Filters
Manage thermal energy with precision optical design
Heat control filters are specialized optical components designed to effectively manage infrared radiation while maintaining optimal visible light transmission. These filters work by selectively reflecting or transmitting different portions of the electromagnetic spectrum, allowing precise control over thermal energy in optical systems. Each type of heat control filter is characterized by its specific spectral response:
- Hot Mirrors: Transmit visible light while reflecting infrared radiation
- Cold Mirrors: Reflect visible light while transmitting infrared radiation
- UV Cold Mirrors: Efficiently reflect UV while transmitting visible and infrared
- IR Suppressing Filters: Extended blocking across the infrared spectrum
Andover Corporation's heat control filters utilize advanced thin-film dielectric coatings deposited on thermally-stable substrates like borosilicate glass. This construction ensures reliable performance even in high-power illumination applications. The combination of hot and cold mirrors can eliminate up to 99% of unwanted radiation, making these filters essential components in applications ranging from projection systems to medical lighting.
