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, ensuring optimal performance in demanding environments. The use of high-quality Borosilicate type glass allows these mirrors to operate efficiently under high temperatures, making them a reliable choice for both industrial and scientific applications.
Hot Mirrors are specifically engineered to separate visible light from heat by reflecting infrared radiation. This capability is crucial in applications where heat management is necessary to protect sensitive components or maintain system efficiency. The preferred angle of incidence (AOI) for hot mirrors is 0º, and they offer an impressive average transmission of 85% within the 420-700nm wavelength range. Additionally, they provide a high reflection rate of over 95% for wavelengths between 800-1000nm, ensuring that unwanted heat is effectively redirected.
On the other hand, Cold Mirrors are designed to reflect visible light while allowing heat to pass through. This feature is particularly beneficial in lighting and projection systems where heat dissipation is required to prevent overheating. Cold mirrors operate optimally at an AOI of 45º and exhibit an average transmission rate of over 85% for wavelengths ranging from 800-1200nm. They also achieve a reflection rate of over 95% for the visible spectrum (400-700nm), ensuring bright and clear light output.
Both hot and cold mirrors are available in various sizes, ranging from 15mm to 300mm, with a standard thickness of 3.3mm. They are coated with a dielectric multilayer to enhance their reflective and transmissive properties. The mirrors also feature a protective bevel to ensure durability and longevity. For those with specific requirements, custom configurations are available to meet unique application needs.
