AR2S-VIS-01 AR delivers Coating type Broadband multi-layer (BBAR) (double-side coated), Design waveband 400 – 700 nm, and Average reflectance (Ravg) < 0.62 % per surface.
The hard-oxide coating is built for repeated handling, heat, and cleaning.
Best suited for:
Camera and projector optics where ghost images and flare from surface reflections degrade contrast and colour fidelity — this AR coating recovers lost light and suppresses stray reflections across the full visible spectrum
Description
AR2S-VIS-01 is a double-side broadband anti-reflection coating engineered to maximize transmission across the full visible spectrum from 400 nm to 700 nm. Average transmission exceeds 98.7 % over that window, with peak values reaching 99.3 % near 495 nm. From blue through red, every channel delivers > 98 % throughput, ensuring virtually lossless light transfer. Reflectance per surface drops well below 1 %, making this coating ideal for any application where stray reflections degrade image quality or detector signal.
Key Advantages
- Tavg > 98.7 % across 400-700 nm - delivers near-unity transmission for the entire visible band, minimizing insertion loss in imaging and display optics.
- Peak transmission of 99.3 % at 495 nm - places maximum throughput squarely in the green-cyan region where the human eye is most sensitive.
- Broad high-performance zone - T > 95 % extends from 388 nm to 793 nm, offering strong performance even into near-UV and far-red.
- Hard-oxide durability - ion-assisted deposition produces a coating that resists heat, humidity, solvents, and repeated cleaning with no measurable degradation.
- 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
- Machine-vision cameras and industrial inspection - eliminates ghost reflections and boosts contrast in high-speed imaging systems operating under broadband illumination.
- Microscopy and life-science imaging - maintains faithful colour reproduction across blue, green, and red fluorescence channels without inter-channel signal loss.
- Projection and display optics - ensures maximum brightness and colour accuracy for DLP, LCD, and LCOS projection engines.
- Cinematography and broadcast lenses - reduces flare and veiling glare across the visible band for sharper, cleaner imagery.
- Laser-line optics (visible wavelengths) - provides low-loss windows for 405 nm, 488 nm, 532 nm, and 633 nm laser lines.
