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 crucial. Whether you need to separate visible light from heat or reflect visible light while transmitting heat, these mirrors offer a reliable solution.
Hot Mirrors are specifically engineered to reflect heat while allowing visible light to pass through. This is achieved using Borosilicate type glass, which is known for its ability to withstand high temperatures. The preferred angle of incidence (AOI) for optimal performance is 0º. These mirrors are highly efficient, with an average transmission of 85% within the 420-700nm wavelength range, and they reflect more than 95% of wavelengths between 800-1000nm. This makes them ideal for applications where heat needs to be managed without compromising on visible light transmission.
Cold Mirrors, on the other hand, are designed to reflect visible light while allowing heat to pass through. They are most effective when used at an AOI of 45º. These mirrors offer an impressive transmission range of over 85% for wavelengths between 800-1200nm, while reflecting more than 95% of visible light in the 400-700nm range. This unique capability makes cold mirrors perfect for applications where it is necessary to remove heat by transmission while maintaining high visibility.
Both hot and cold mirrors are available in various sizes and can be customized to meet specific requirements. They are constructed with a dielectric multilayer coating on Borosilicate type glass, ensuring durability and high performance. Whether you need a standard size or a custom configuration, these mirrors provide a versatile solution for managing light and heat in your optical systems.
