AR1S-VNIR-01 AR delivers Coating type Broadband multi-layer (BBAR) (single-side coated), Design waveband 400 – 1000 nm, and Average reflectance (Ravg) < 6.49 % per surface.
The hard-oxide coating is built for repeated handling, heat, and cleaning.
Best suited for:
Machine vision systems operating across visible and near-infrared wavelengths where surface reflections reduce signal-to-noise ratio and introduce ghost images in high-sensitivity industrial cameras
Description
AR1S-VNIR-01 is a single-side anti-reflection coating optimized for the green through near-infrared range, covering 550 nm to 950 nm. Average transmission exceeds 95.6 % across this 400 nm window, with peak values reaching 96.0 % near 799 nm. The coating holds T > 95 % from 530 nm to beyond 1000 nm, delivering a remarkably flat response across the green, red, and NIR bands. Below 530 nm, transmission rolls off steadily, reaching 48 % at 500 nm, so blue-channel performance is limited by design - the coating concentrates its anti-reflection power where it matters most for NIR-extended imaging.
Key Advantages
- Tavg > 95.6 % across 550-950 nm - maximizes throughput from green through NIR on a single-side coating, well suited for silicon-sensor wavelengths.
- Flat spectral profile - T > 95 % from 530 nm to beyond 1000 nm ensures uniform signal across all channels with < 1 % ripple.
- NIR extension past 950 nm - maintains > 95.9 % at 1000 nm, supporting applications that reach into the tail of the silicon detector response.
- Hard-oxide durability - ion-assisted deposition produces a coating that resists heat, humidity, solvents, and repeated cleaning.
- Custom formats available - round, square, or free-form blanks from 5 mm to 450 mm, thickness 0.21-3.8 mm, on Borofloat®, soda-lime, Schott D263 T, or Corning Eagle XG substrates.
Typical Applications
- Precision agriculture and NDVI sensing - passes the red (660 nm) and NIR (850 nm) channels required for vegetation health analysis through a single coated optic.
- Machine-vision systems with NIR illumination - reduces surface losses for cameras operating under 850 nm LED or laser illumination for gesture recognition, eye tracking, and quality inspection.
- Fluorescence microscopy (green-red-NIR channels) - supports GFP (green fluorescent protein) emission, Cy5 (red), and NIR dye detection without changing optical coatings.
- Solar-cell characterization - provides a flat-response window covering the peak-power portion of the AM1.5 solar spectrum (550-950 nm).
- Drone and UAV imaging - enables compact multispectral payloads that capture green, red, red-edge, and NIR bands through a shared optical path.
