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
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
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
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. RAMAN REJECT FILTERS
