Single-side broadband AR: 95 % T from 420–720 nm, > 94 % average across the whole visible—brighter images and less ghosting while leaving one face free for bonding.
BH-A05 is KUPO’s single-side broadband anti-reflection solution for systems that still
need a bare reference face—whether for optical cementing, sensor epoxy, or an additional
IR-cut/ITO stack. An ion-beam-sputtered oxide design drives reflections on ordinary
soda-lime or Borofloat® glass to the noise floor, boosting total hemispherical
transmission to > 94 % average and peaking around 96 % through the eye-sensitive
420–720 nm region.
The coating easily meets MIL-C-675C environmental and adhesion specs, resists moderate
abrasion, and is deposited in fully automated IBS chambers for sub-percent lot-to-lot
consistency. Sheet sizes up to 450 × 650 mm and thicknesses from 0.5 – 6 mm are
supported on Borofloat®, Schott D 263 T, fused silica, soda-lime, or acrylic. Prototype
windows ship in as little as a week, with volume runs queued to your schedule.
Typical uses: camera cover glass, AR combiners (air-side AR / waveguide inner face),
bright display touch panels, high-NA cuvettes and flow-cells, and stray-flare suppression
in fast LED/laser-phosphor optics.
BH-A05 is a single-side broadband AR coating that drives reflections on ordinary glass down to the noise floor while pushing total hemispherical transmission past 94 % across the full visible spectrum. Starting around 380 nm the stack climbs rapidly, plateaus at 95 – 96 % through the 420 – 720 nm band, and stays above 93 % out to 780 nm. The result: brighter images, better contrast, and less ghosting in any application that still needs one un-coated reference face or bonding surface on the opposite side.
Key advantages
> 94 % Tavg (s-pol, 0°) – boosts system throughput by ~8 % versus uncoated soda-lime windows.
Single-side architecture – leaves the second face bare for optical cementing, sensor epoxy, or IR-blocking over-coat.
Durable oxide stack – passes MIL-C-675C adhesion, humidity, and moderate abrasion without crazing.
Large-format capable – up to 450 mm × 650 mm sheets, 0.5 – 6 mm thick, on Borofloat®, D 263 T, fused silica, or acrylic.
Typical applications
Camera & projector cover plates – squeeze extra f-stops of light onto sensors or DLP chips.
Augmented-reality combiners – minimise forward reflections on the air side while leaving the inner face for waveguide coupling.
Display touch panels – raise brightness and cut sparkle on phone, tablet, and HUD glass.
Scientific cuvettes & flow cells – improve signal-to-noise in absorbance and fluorescence channels.
Lighting optics – stop lens ghosting and stray flare in high-CRI LED or laser-phosphor fixtures.
