Description
Hot and Cold Mirrors are essential optical components designed to manage light and heat in various applications. These mirrors are crafted using high-quality Borosilicate type glass, known for its ability to withstand high temperatures, ensuring durability and reliability in demanding environments. The primary function of hot mirrors is to separate visible light from heat by reflecting the latter. This is achieved with an average transmission of 85% within the 420-700nm wavelength range, while effectively reflecting heat in the 800-1000nm range with a reflectivity greater than 95%. The preferred angle of incidence (AOI) for optimal performance is 0º.
On the other hand, Cold Mirrors are engineered to reflect visible light while allowing heat to pass through, making them ideal for applications where heat removal is crucial. These mirrors operate best at an AOI of 45º, with a transmission range of 800-1200nm and an average transmission greater than 85%. They reflect visible light in the 400-700nm range with a reflectivity exceeding 95%. The use of dielectric multilayer coatings enhances the performance of both hot and cold mirrors, providing high transmission and reflection rates tailored to specific needs.
Both hot and cold mirrors are available in various sizes, ranging from 15mm to 300mm, with a standard thickness of 3.3mm. The surface finish is maintained at 80-50, and the flatness is measured at λ/2 @ 633nm per inch, ensuring precision and quality. Additionally, a protective bevel of 0.3mm x 45º is applied to safeguard the edges. For those with unique requirements, custom mirrors can be manufactured to specific configurations, offering flexibility and adaptability to diverse applications.
