Custom Optical Windows
Optical windows protect sensors, lasers and imaging systems while preserving transmission and wavefront quality. We review the substrate, spectral band, aperture, surface quality, flatness, parallelism, edge geometry and environmental load as one specification.
Materials & wavelength
Substrate routes
Optical glass, fused silica, sapphire, CaF₂, BaF₂, silicon, germanium and ZnSe, subject to wavelength and environment.
UV, visible, VIS–NIR, MWIR and LWIR routes are reviewed by substrate and coating.
End use
Typical applications
- Laser and beam-delivery protection
- Camera, detector and instrument covers
- Vacuum, pressure and environmental barriers
- Thermal-imaging and infrared sensing systems
Engineering discussion framework
Reference manufacturing and RFQ targets
These values show the type of requirement that can be evaluated. They are not a blanket capability guarantee. The signed quotation, approved drawing, sample and inspection plan control the final product.
| Parameter | Reference target / quotation note |
|---|---|
| Size route | Reference RFQ target: Ø0.5–600 mm; rectangular parts up to 1000 × 600 mm. Large formats require separate process review. |
| Clear aperture | Central 90% is a common target; drawing-controlled apertures are also reviewed. |
| Surface flatness | Targets down to PV λ/40 at 632.8 nm may be evaluated according to material, size and test aperture. |
| Surface quality | 10-5 scratch-dig target can be evaluated; commercial grades are available for cost-sensitive projects. |
| Parallelism / wedge | Parallelism below 3 arcsec or a controlled wedge angle may be specified. |
| Coating | Uncoated, single-band AR, BBAR, high-reflection or project-specific spectral designs. |
Faster technical review
What to include in your RFQ
- 2D drawing with diameter/length, thickness and edge details
- Substrate or working spectral band
- Flatness, surface quality, parallelism or wedge
- Clear aperture and coating performance
- Quantity, inspection report and environment
Final acceptance: Confirm all numerical values, material grade, coating curve, metrology, sampling plan and documentation on the purchase specification.

Attach drawings or spectra where possible. Factory visits and supplier audits are available by appointment for qualified projects after the route is confirmed.
Buyer questions
Optical Windows FAQ
How do I choose an optical-window material?
Start with wavelength, transmission, thermal environment, mechanical load and budget. Fused silica is common for UV-to-NIR work, while crystalline and semiconductor materials are reviewed for infrared bands.
Does a protective window affect image quality?
It can. Flatness, wedge, transmitted wavefront, coating, thickness and installation angle may influence focus, ghosting and aberration. Include the system geometry in the RFQ.
Can large or non-round windows be quoted?
Yes. Rectangular, square and other drawing-defined shapes can be reviewed. Size, aspect ratio, material, flatness and edge support determine the practical route.
