IR Reflecting Filters
Thin-Films Research Inc
We produce several types of Heat Reflecting Filters using Durable multi-layer Dielectric coatings. By adding these filters directly to the beam path, the temperature can be reduced by effectively reflecting IR radiation while transmitting more than 85% of the visible spectrum. Some of these filters also provide the added benefit ...

Did You know?

Optical filters selectively transmit light in a particular range of wavelengths. When designed to pass short wavelengths only, they are referred to as short-pass filters. Short-pass filters are widely used in optical instruments for applications such as fluorescence microscopy and Raman spectroscopy. They may also be used in operations like stage lighting and entertainment. Short-pass filters are commonly paired with long-pass filters to create custom band-pass filtering. This allows for the transmission of a specific wavelength range that is tailored for customer requirements.
