Phillips Safety is proud to offer a broad portfolio of glass optical filters. Glass optical filters are known for their selective absorption in the visible wavelength range. If their filter effect lies within the visible light spectrum, they appear to be colored.
Glass optical filters are perfect for a wide variety of applications in diverse fields. These include medical and biotech, consumer electronics, safety and security, astronomy, and industrial equipment.
The glass optical filters at Phillips Safety include a selection of filter types in the wavelength range above 200 nm. They are bandpass filters, shortpass filters, longpass filters, neutral density filters, and notch filters.
When it comes to their differences, 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.
Next we have a shortpass filter, which is an optical interference or colored glass filter. It attenuates longer wavelengths and transmits (passes) shorter wavelengths over the active range of the target spectrum (usually the ultraviolet or visible region).
We also have a longpass filter, 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).
To add to it, neutral density filters have a constant attenuation across the range of visible wavelengths. They are used to reduce the intensity of light by reflecting or absorbing a portion of it.
Finally, a notch filter passes all frequencies except those in a stop band centered on a center frequency.
