Hot and cold mirrors, commonly known as "heat control filters," play a pivotal role in managing light emissions effectively. These dichroic filters serve the purpose of selectively reflecting or transmitting specific wavelengths, addressing the need to control heat and optimize visible light for various applications.
In this article, we delve into the distinctions between hot and cold mirrors, exploring their unique characteristics, applications, and manufacturing processes. From the angle of incidence specifications to the materials used, we touch on the science behind these dichroic filters and the practical applications of cold mirrors, emphasizing their role in safeguarding optical fibers from harmful UV and IR radiation. By isolating specific bandwidths, these filters prove instrumental in scenarios where controlling the light spectrum is critical for optimal performance.
