Description
Hot and Cold Mirrors are essential optical components designed to manage light and heat in various applications. These mirrors are crafted with precision to either reflect or transmit specific wavelengths, making them invaluable in environments where temperature control and light management are critical. The use of high-quality Borosilicate glass ensures durability and performance even in high-temperature settings, providing a reliable solution for demanding optical systems.
Hot Mirrors are specifically engineered to separate visible light from heat by reflecting infrared radiation while allowing visible light to pass through. This capability is particularly useful in applications where heat needs to be managed without compromising the quality of visible light. The preferred angle of incidence (AOI) for optimal performance is 0º, with a common wavelength range for transmission between 420-700nm and a reflection range of 800-1000nm. This makes hot mirrors ideal for systems that require high transmission of visible light and effective heat management.
Cold Mirrors, on the other hand, are designed to reflect visible light while transmitting infrared radiation, effectively removing heat from the system. These mirrors are best operated at an AOI of 45º, with a transmission range of 800-1200nm and a reflection range of 400-700nm. Cold mirrors are perfect for applications where visible light needs to be maximized while minimizing heat, ensuring that optical systems remain cool and efficient.
Both hot and cold mirrors are available in various sizes and configurations, with the option for custom designs to meet specific requirements. The use of dielectric multilayer coatings enhances their performance, providing high transmission and reflection rates. Whether you need to manage heat in a lighting system or optimize the performance of an optical device, hot and cold mirrors offer a versatile and effective solution.
