Optical Filters

Product catalog summary

Optical Filters Overview
Ealing provides a variety of optical filters, including bandpass, edgepass, color glass, neutral density, heat control filters, and diffusers. These filters are designed for different spectral ranges and applications, ensuring high performance and durability.

Bandpass Filters
Ealing offers bandpass filters for UV, VIS, and IR ranges. UV filters use synthetic fused silica substrates, while VIS and IR filters use glass substrates. They are available in diameters of 1/2” and 1”. Each filter comes with a desiccant capsule and a spectrophotometer lot sample trace. The spectral ranges are UV (200-380 nm), VIS (390-780 nm), and NIR (790-1550 nm).

Edgepass Filters
These filters provide sharp cut-on and cut-off for a wide range of wavelengths and can be used for separating spectral orders or as heat or UV filters. They are available in the VIS-NIR range (400-1000 nm) with a 1” diameter.

Color Glass Filters
Standard absorbing Schott glasses are available for various applications, ensuring repeatability. Glass types include BG, FG, GG, KG, OG, RG, UG, VG, and WG, available in 1” diameter or 2” square sizes.

Neutral Density Filters
These filters are available in absorptive and reflective types, with optical densities ranging from 0.1 to 5.0 OD for absorptive and 0.1 to 4.0 OD for reflective. They come in 1” diameter and 2” square sizes, with continuous-variable reflective options available in round and rectangular sizes.

Heat Control Filters
Options include cold mirrors at 45°, hot mirrors at 0° or 45°, and UV cold mirrors at 45°.

Diffusers
Available in holographic for top hat distribution and glass for uniform illumination.

Custom Solutions
Ealing is open to discussing specific requirements for filters not listed in the catalog and offers quotes for volume OEM requirements.

Catalog excerpts

Optical Filters Bandpass Filters Ealing offers three series of bandpass filters for UV, VIS, and IR ranges. The UV filters use synthetic fused silica substrates, whereas the VIS and IR filters use glass substrates. Specifications are different for each range of products. Each filter is individually packaged with a desiccant capsule for extended shelf life and a measured spectrophotometer lot sample trace is supplied with each filter. UV, 200-380 nm, VIS, 390-780 nm and NIR, 790-1550 nm in 1/2” and 1” diameters. Edgepass Filters Short and long wave for a wide range of wavelengths with very sharp cut-on and cut-off. They may be used to separate spectral orders, in pairs as variable bandpass filters, and as heat or UV filters. VIS-NIR, 400-1000 nm in 1” diameter. VIS-NIR, 400-1000 nm, 1” diameter. Color Glass Filters Standard absorbing Schott glasses for repeatability and wide variety of applications. Glass types: BG, FG, GG, KG, OG, RG, UG, VG and WG in 1” diameter or 2” square. Neutral Density Filters Absorptive, 0.1-5.0 OD, 1” diameter, 2” square. Reflective, 0.1-4.0 OD, 1” diameter, 2” square. Continuous-variable reflective, choice of ranges, 0.4-3.0 OD round and rectangular sizes available. Heat Control Filters Cold mirror 45°, hot mirror 0° or 45°, UV cold mirror 45°. Diffusers Holographic - top hat distribution. Glass - uniform illumination.
