Optical Coating Options

Custom Coating

Per your wavelength and performance requirements.

Typical use: All custom applications

How to Specify Your Coating

To select the right coating, please provide: (1) Operating wavelength, (2) Angle of incidence, (3) Required transmission or reflectivity, (4) Laser power density (if applicable), (5) Operating environment.

Engineering Considerations

Key factors to evaluate when specifying this optical component for your system.

Wavelength Range

Custom has specific transmission characteristics. Verify compatibility with your operating wavelength.

Surface Quality

Specify based on application: 40-20 for general, 20-10 for precision, 10-5 for laser-grade.

Flatness

λ/4 standard. Tighter specifications available for wavefront-critical systems.

Environmental

Consider thermal, chemical, and mechanical environment when selecting window material.

Applications

Laser Systems

Beam delivery, focusing, and conditioning for industrial and scientific laser systems.

Semiconductor

Wafer inspection, lithography support, and process control optics.

Machine Vision

Image formation in inspection systems and quality control cameras.

Research & Education

Laboratory optics, teaching setups, and experimental beam paths.

Frequently Asked Questions

What sizes are available?

Standard diameters range from 5mm to 100mm with thicknesses from 1mm to 50mm. Larger sizes and custom shapes are available upon request.

Can these windows be used in vacuum environments?

Most optical window materials are compatible with vacuum environments. Fused silica and sapphire have very low outgassing characteristics.

What surface quality do you recommend?

For laser applications, 10-5 is recommended. For general-purpose windows, 20-10 is acceptable and more economical.

Can I specify a custom shape?

Yes. Circular, rectangular, square, and custom shapes are available. Provide your drawing or dimensional requirements for a quotation.

What flatness should I specify?

λ/10 is standard for precision applications. For wavefront-critical systems, λ/20 or tighter is available. Note that tighter flatness directly affects cost.

How do I specify a custom window?

Provide: material, diameter/shape, thickness, wavelength, surface quality, flatness, coating requirements, and quantity.

How do I submit a custom drawing?

Upload your drawing via the RFQ form. Include material, dimensions, tolerances, surface quality, flatness, coating, and quantity.

What is the typical lead time?

Simple custom windows: 2-3 weeks. Complex designs: 4-6 weeks. Prototypes may be faster.
