Optical Filter Glass
         
Phillips Safety offers a broad portfolio of optical filter glasses for a full spectral solution that meets your requirements. Optical filter glass is known for its selective absorption in the visible wavelength range. The optical filter glasses appear to be colored if their filter effect lies within the visible light spectrum. Perfect for a wide variety of applications in such diverse fields as medical and biotech, consumer electronics, safety and security, astronomy, and industrial equipment.
         
  2" x 2" Optical Filter Glass   6.5" x 6.5" Optical Filter Glass  
         
  Perfect for small viewing applications on laser enclosures and for custom beam attenuation.   Perfect for viewing windows on doors and portholes.  
         
 

Our optical filter glasses include the following filter types
in the wavelength range above 200 nm:

Bandpass Filters:
Bandpass filters block all but a particular wavelength. The width of such a filter is expressed in the wavelength range it lets through and can be anything from much less Angstrom to a few hundred nanometers.
 
Shortpass Filters:
A shortpass filter is an optical interference or colored glass filter. It attentuates longer wavelengths and transmits (passes) shorter wavelengths over the active range of the target spectrum (usually the ultraviolet or visible region).
 
Longpass Filters:
A longpass filter is an optical interference or colored glass filter. It attenuates shorter wavelengths and transmits (passes) longer wavelengths over the active range of the target spectrum (ultraviolet, visible, or infrared).
 
Neutral Density Filters:
Neutral Density filters have a constant attenuation across the range of visible wavelengths, and are used to reduce the intensity of light by reflecting or absorbing a portion of it.
 
Notch Filters:
A Notch filter is a filter that passes all frequencies except those in a stop band centered on a center frequency.
