AR1S-SWIR-01 AR delivers Coating type Broadband multi-layer (BBAR) (single-side coated), Design waveband 900 – 1700 nm, and Average reflectance (Ravg) < 3.97 % per surface.
The hard-oxide coating is built for repeated handling, heat, and cleaning.
Best suited for:
SWIR imaging systems operating in the 900–1700 nm band — including InGaAs camera optics, moisture detection sensors, and semiconductor inspection equipment — where surface reflections reduce already-limited SWIR signal levels
Description
AR1S-SWIR-01 is a single-side anti-reflection coating optimized for the short-wave infrared range from 1260 nm to 1630 nm. Average transmission across this 370 nm window exceeds 97.3 %, with peak values reaching 97.6 % near 1616 nm. The coating holds T > 95 % from 1186 nm to beyond 1800 nm, providing a broad, flat throughput plateau that covers the full O-, E-, S-, C-, and L-telecom bands. Performance builds steadily from the 1000 nm measurement start, reaching usable levels (> 90 %) by 1143 nm and full specification by 1260 nm.
Key Advantages
- Tavg > 97.3 % across 1260-1630 nm - provides high, uniform throughput spanning the full telecom O-through-L band range on a single-side coating.
- T > 95 % from 1186-1800 nm - extends high performance well beyond the specified window, supporting broadband SWIR applications.
- Peak of 97.6 % at 1616 nm - centres best performance in the L-band, complementing C-band telecom and SWIR imaging needs.
- Hard-oxide durability - ion-assisted deposition ensures long-term stability under heat, humidity, and routine 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
- Telecom component optics - reduces insertion loss in DWDM (Dense Wavelength Division Multiplexing) modules, optical amplifiers, and fibre couplers operating from O-band to L-band.
- InGaAs camera systems - maximizes photon collection for SWIR imaging sensors used in semiconductor inspection, moisture mapping, and see-through-fog applications.
- Gas absorption spectroscopy - covers key absorption lines for H2O, CO2, CH4, and NH3 in the 1300-1650 nm region, supporting environmental and process-control monitoring.
- Eye-safe LiDAR at 1550 nm - minimizes window losses for 1550 nm ranging systems where high signal return is essential for long-range performance.
- Defence and covert imaging - enables high-throughput SWIR windows for night-glow imaging and covert laser illumination systems.
