AR2S-MP-01 AR delivers Coating type Broadband multi-layer (BBAR) (double-side coated), Design waveband 400 – 700 nm, and Average reflectance (Ravg) < 0.59 % per surface.
The hard-oxide coating is built for repeated handling, heat, and cleaning.
Best suited for:
Precision optical instruments operating in the visible spectrum where even small surface reflections introduce measurement errors — this AR coating provides the lowest possible reflectance across the 400–700 nm design band
Description
AR2S-MP-01 is a double-side broadband anti-reflection coating optimized for the core visible range from 425 nm to 680 nm. Average transmission across this window reaches an exceptional 99.5 %, with peak values touching 100 % in the green-red region near 653 nm. The coating holds T > 99 % from roughly 435 nm to 675 nm, delivering the kind of near-zero-loss performance that demanding optical trains require. Outside the primary band, transmission remains > 90 % from 404 nm to 728 nm, providing substantial headroom into deep blue and far red.
Key Advantages
- Tavg > 99.5 % across 425-680 nm - achieves near-perfect throughput across the central visible range, reducing cumulative insertion loss in multi-element optical assemblies.
- Peak transmission at 100 % near 653 nm - eliminates virtually all surface reflection at red wavelengths, ideal for HeNe laser lines and red LED sources.
- Exceptionally flat passband - T > 99 % from 435 nm to 675 nm ensures uniform colour rendering with no spectral bias.
- Hard-oxide durability - ion-assisted deposition creates a coating that resists heat, humidity, solvents, and repeated cleaning without 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
- High-end imaging and cinematography - minimizes ghosting and maximizes contrast across the visible band where image quality is most critical.
- Microscopy and pathology - maintains faithful colour reproduction for stained-tissue imaging under broadband visible illumination.
- Laser-line optics at 532 nm and 633 nm - provides near-zero-loss transmission at two of the most commonly used visible laser wavelengths.
- Projection and display systems - boosts brightness and colour purity in multi-lens projection engines where cumulative reflection losses are significant.
- Spectrophotometry and colorimetry - delivers a spectrally neutral window that does not distort the measurement of visible-band optical properties.
