What are commonly referred to as optical heat shields, thermal mirrors, and infrared reflectors?

What are the commonly used optical insulation sheets, thermal mirrors, and infrared reflectors in the field of optics?

Thermal mirrors, also known as thermal reflectors, optical insulation sheets, and infrared reflectors, are commonly referred to as optical thermal mirrors in the field of optics, except for some differences in specific dimensions and optical parameters

A thermal mirror is a type of thermal reflector designed to be used as a short-pass filter, capable of transmitting visible light wavelengths at a 0 ° incidence angle while reflecting near-infrared light and heating wavelengths. Remove unnecessary heat from the optical system. The specific dimensions and parameters can be customized according to customer specific requirements

Advantages of Hanzhong Borisun Optical Insulation Sheet:

High isolation near-infrared energy (cut-off from 720nm to 2500nm); Effectively isolate sunlight and heat from metal halide lamps, ensuring effective utilization of visible light reflection by 90% and absorption by 10% for complete insulation; High temperature resistant glass, not cracked! There are two options available: UV cut-off and non cut-off, with long-term inventory available and both large and small batches available
