AR1S-MULTI4-01 Anti-reflection coating

Anti-reflection coating (AR1S-MULTI4-01)

AR1S-MULTI4-01 is an anti-reflection coating. The measured curve shows a high-transmission region at approximately 1010-2050 nm. Use it when you want to pass a broad range of wavelengths. Add a separate filter if you need to select a specific band.

Optical performance

• Measured wavelength range: 900-2050 nm. Performance outside this measured interval is not established by this curve.
• Selected regions at or above 80% transmission: 1010-2050 nm. Approximate measured intervals.
• Selected regions at or below 5% transmission: 900-923 nm. Measured sample intervals; confirm the required blocking for your order.
• Peak transmission: Approximately 97.6% at 1611 nm. Peak wavelength is not the same as a defined centre wavelength.
• Average measured transmission, 1024-1104 nm: 95.694%. Calculated from the factory sample data.
• Average measured transmission, 1260-1340 nm: 96.607%. Calculated from the factory sample data.
• Average measured transmission, 1480-1650 nm: 97.444%. Calculated from the factory sample data.
• Average measured transmission, 1960-2040 nm: 96.176%. Calculated from the factory sample data.
• Customization: We can customize stock and sample-book designs. Tell us the wavelength response, size and operating conditions you need.

These values come from the measured samples and help you choose a starting design. We will agree the final specification for your order. Custom versions have their own specifications and measured curves.

Applications to consider

• Infrared optical windows: Consider this window when the wavelengths you want to pass fall within 1010-2050 nm. Confirm the substrate and coated surfaces for the assembly.
• Shared optical paths: Consider it when several wavelengths need to pass through the same window. Add separate spectral selection if the channels need to be isolated.
• Instrument throughput improvement: Check how much light the coated optic passes against the needs of your system. Confirm reflectance, working angle and surface quality for your design.

Choosing this filter

• Transmission is broadband and does not itself separate wavelength channels. Confirm the required reflectance, coated surfaces, substrate and angle of incidence.

Custom options

Start with this stock or sample-book design, then tell us what you need to change. We can discuss the wavelength bands, transmission, blocking, angle, glass material, size and operating conditions with you, and agree a specification for your custom filter.
