CUSTOM OPTICAL FILTERS
Custom Optical Filters
Optical Filters transmit light of different wavelengths to attenuate or enhance an image and to transmit or reflect specific wavelengths. All Optical Filters pass, absorb, and/or reflect light.
We have a large variety of Optical Filters available at Sterling Precision Optics, Inc. Below is a listing of the most commonly used in the optical industry today.
Colored Glass Filters
Colored glass filters are made from special filter glass material with different absorption and/or transmission properties across a specified spectral region. The raw material for colored glass filters can be in sheets, strips, blanks or blocks.

Heat Absorbing Filters
Heat absorbing filter glass will transmit visible light and absorb infrared radiation. The absorbed IR is dissipated as heat into the cooled air around the optical assembly. Heat absorbing filters are typically tempered or toughened (heat treated) so that the glass will not crack due to the expansion and contraction caused by the heating and cooling. The tempering department at Sterling Precision Optics, Inc. has 5 ovens to handle all types and sizes of glass
Heat Absorbing Glasses Recommended
Long Pass Filters
These filters pass long wavelengths only and are made from colored glass filter material and/or special optical coatings.
Long Pass Filters Glasses Recommended
Short Pass Filters
These filters pass only short wavelengths and are also made from colored glass filter material and/or special optical coatings.
Short Pass Filters Glasses Recommended
Neutral Density Filters
Neutral Density or ND Filters evenly reduce the transmission across a portion of a certain spectrum (wavelength) visible, ultraviolet or infrared. There are two types of ND Filters: absorptive and reflective. The absorptive filter absorbs light that is transmitted through a specified filter glass. A reflective filter reflects the light back using a specified optical coating.
Neutral Density Glasses Reccommended
Dichroic filters have an optical coating that transmits and reflects a given spectrum. They are typically used as color filters and are slightly angle sensitive.
Bandpass filters have either extremely narrow band (<2nm to 10nm) or they have a broadband (50nm to 80nm) transmission across the filter. They are very angle sensitive care must be taken when installing in an optical assembly.

A hot mirror, featuring an optical coating that reflects infrared (IR) radiation while permitting visible wavelengths to pass through, plays a crucial role in various applications where managing heat and light transmission is essential. Sterling Precision offers specialized solutions that align with the unique attributes of hot mirrors, enhancing their functionality across diverse applications.
The optical coatings designed by Sterling Precision are tailored to exhibit optimal reflectance in the infrared region, effectively preventing the transfer of heat associated with these wavelengths. Simultaneously, these coatings ensure high transmittance for visible light, maintaining the integrity of the desired spectral output.
In optical systems, Sterling Precision's hot mirrors prove invaluable for minimizing heat buildup by efficiently reflecting infrared radiation away from sensitive specimens and components. This enhances the overall efficiency and performance of optical systems, ensuring longevity and reliability.
For applications in lighting, Sterling Precision's expertise in hot mirrors enables precise control over the spectral output of light sources. By allowing visible light to pass through while reflecting infrared radiation, these hot mirrors contribute to the creation of lighting solutions that are not only visually appealing but also energy-efficient.
