Our colored glass filters serve as broadband, bandpass, or long-wave pass filters. We have expanded our offering to a variety of 41 different Schott and Hoya color glasses covering the UV, visible, and near-infrared wavelength regions. These filters are precision polished for demanding research or OEM applications. They are available in three sizes—12.7 mm diameter, 25.4 mm diameter and 50.8 mm square.
Schott and Hoya colored glass filters are widely used for order sorting, light attenuation, and spectral selection of a broadband source. They are significantly less expensive than multi-layer coated filters which have sharper cut-on and cut-off wavelengths and better rejection.

25.4 mm diameter and 50.8 mm square colored glass filters are available individually or in a set of twelve. The set consists of one of each filter available packaged in a protective hardwood case. All filters are shipped with a transmission curve. For easy identification, The 25.4 mm diameter and 50.8 mm square filters are permanently labeled.

Specifications

Material	Schott, Hoya colored glass or equivalent
Clear Aperture	≥central 80% of dimensions
Surface Quality	60-40 scratch-dig
Dimensions	±0.3 mm
Thickness	3.0 ±0.1 mm (2.0 ±0.1 mm for UG.11 and BG.18 filters)
Wedge	≤3 arc min
Chamfers	0.25–0.76 mm face width x 45° ±15°
