Near Infrared (NIR) Coatings
BBAR BARC-11
This broadband coating provides a low level of reflectance across a wide spectrum from 400-1100nm, reflecting less than 1.0% average. Standard and custom coatings are available for refractive indices of 1.46 to 1.90.
Narrow Band AR
nominally centered @1550 nm
This narrow band AR is an excellent coating for targeting a single wavelength or very narrow band of wavelengths at or near 1550nm. Standard < 0.25% and high performance < 0.05% reflectivity specifications are available.
AR Coating 425 – 950nm NIR Bias
- VIS-NIR coating compensates for weak diode signal
- Ravg < 1% 425-900nm & R < 0.5% NIR, (AOI = 0-30º)
- Also available with oleo/hydrophobic properties
AR Coating SWIR 900 – 1700nm
- Coating for machine vision & spectral analysis
- Ravg < 1.0%/1.5% 900-1700nm (AOI = 0/30º)
- Also available with oleo/hydrophobic properties
AR Coating Diode 1550nm
- Low loss coating R < 0.1% for 1550nm
- Maximum signal preservation for diode emitters
- Accommodates diode spectral variance/thermal drift
