Intlvac can provide custom optical filters for a diverse range of substrates and for the VIS, NIR, SWIR, and MWIR spectral regions. Below lists examples of a few of these coatings.
1. SINGLE AND MULTI BANDPASS FILTERS
Coating Description
A bandpass filter is designed to transmit energy only within a selected band of wavelengths in the spectrum and reject all other wavelengths
Durability Performance
Adhesion, severe abrasion, humidity as per the following (where applicable): MIL-C-675, MIL-M-13508, MIL-M-14806, MIL-C-48497, MIL-F-48616, MIL-STD-810F
2. LONG WAVE PASS (LWP) FILTERS
Coating Description
A long-wavelength pass filter transmits energy at wavelengths longer than the cut-on wavelength while energy at wavelengths shorter than the cut-on is attenuated.
Durability Performance
Adhesion, severe abrasion, humidity as per the following (where applicable): MIL-C-675, MIL-M-13508, MIL-M-14806, MIL-C-48497, MIL-F-48616, MIL-STD-810F
3. SHORT WAVE PASS (SWP) FILTERS
Coating Description
A short-wavelength pass filter transmits energy at wavelengths shorter than the cut-off wavelength while energy at wavelengths longer than the cut-off is attenuated.
Durability Performance
Adhesion, severe abrasion, humidity as per the following (where applicable): MIL-C-675, MIL-M-13508, MIL-M-14806, MIL-C-48497, MIL-F-48616, MIL-STD-810F
4. NEUTRAL DENSITY FILTERS
The purpose of the neutral density (ND) coating is to attenuate the incident flux. In its simplest form, the thickness of a single metallic layer is adjusted so that a prescribed transmittance is attained.
5. DICHROIC BEAMSPLITTER
6. FLUORESCENCE LENSES
7. RAMAN REJECT FILTERS
