AR2S-VNIR-01 AR delivers Coating type Broadband multi-layer (BBAR) (double-side coated), Design waveband 400 – 1000 nm, and Average reflectance (Ravg) < 1.25 % 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
AR2S-VNIR-01 is a double-side broadband anti-reflection coating spanning the visible through near-infrared range, from 400 nm to 1000 nm. Average transmission across this entire 600 nm window exceeds 97.5 %, with peak values climbing to 99.5 % near 722 nm. The coating maintains > 96 % throughout the visible band and pushes past 98 % in the near-infrared from 700 nm to 900 nm. Even at the extremes, T > 95 % holds from 378 nm to 996 nm, delivering consistent performance across the full VNIR (visible and near-infrared) working range.
Key Advantages
- Tavg > 97.5 % across 400-1000 nm - covers both visible and NIR in a single coating, eliminating the need for separate optics for silicon-sensor-range applications.
- Peak transmission of 99.5 % at 722 nm - puts peak performance at the visible-to-NIR transition, ideal for sensors with response extending beyond 700 nm.
- Flat visible response - T > 96 % from 400 nm to 700 nm maintains colour balance and eliminates chromatic throughput variation.
- Hard-oxide durability - ion-assisted deposition produces a coating that withstands heat, humidity, solvents, and repeated cleaning cycles.
- 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
- Silicon-sensor imaging (CCD and CMOS) - matches the full sensitivity range of silicon detectors from 400 nm to beyond 950 nm, maximizing signal-to-noise in machine vision and scientific cameras.
- NDVI and precision agriculture - passes both visible colour channels and the 850 nm NIR band required for Normalized Difference Vegetation Index (NDVI) measurements.
- Fluorescence and multispectral microscopy - supports visible excitation and NIR emission channels without swapping optical elements.
- Autonomous vehicles and LiDAR windows - transmits both camera bands (visible) and near-infrared ranging signals (905 nm) through a single protective window.
- Stage and architectural lighting - reduces front-surface reflections on lenses and filters used in LED and laser-based lighting fixtures spanning visible to NIR.
