Omega Optical began with the creation and production of custom optical filters. Our catalog products can provide the performance you need, however, as systems become more complex and specialized, a filter customized to the application is required for a superior performing instrument.
Long and Shortpass filters, also known as "edge filters," have a wide variety of applications throughout many industries. Often used for precise discrimination of adjacent wavelengths, these filters are crucial in controlling signal-to-noise and instrument sensitivity. Long and shortpass filters are fully customizable for use in reflection or transmission configurations and also have functionality for use as beamsplitters or combiners.
We can easily accommodate your order whether you need 1, 25, 100, or 5,000 interference filters. This kind of capacity allows for high volume lots, helping you to achieve low prices.
We offer a variety of filter types including bandpass, narrowband, wideband, longpass, shortpass, rejection band, beamsplitters and mirrors in any of the following configurations:
- Protected & Surface Coatings
- Wavelengths: 190nm – 2500nm
- Substrate Size: 2mm– 200mm (ask about larger sizes)
- Filter Thickness: 0.5 – 50 mm
- Substrate Materials: BK-7, Borofloat, Fused Silica, Sapphire, Germanium, Silicon, colored glasses
Spectrophotometric trace of the passband with a resolution of 0.1nm. Spectrophotometric curves provided with NB and SC filters have a resolution of 0.05nm and are calibrated to atomic emission lines. Transmission accuracy on all spectrophotometric traces is ±1%.
