Custom optical filters are available for applications such as bandpass filters, long wave pass (LWP) filters, short wave pass (SWP) filters, neutral density filters and more. Intlvac provides anti-reflection (AR) coatings for a wide range of substrates and applications across the VIS, NIR, SWIR, and MWIR spectral regions. Below are 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 to 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 Neutral density (ND) coatings are designed to attenuate incident flux. In their simplest form, the thickness of a single metallic layer is adjusted to achieve the prescribed transmittance. 5. DICHROIC BEAMSPLITTER 6. FLUORESCENCE LENSES 7.
