Optical Coating Options

Anti-Reflection (AR)

Single-layer or multi-layer AR coatings for specific wavelength bands. Reduce reflection to below 0.5% per surface.

High-Reflection (HR)

Dielectric HR coatings for laser mirrors and cavity optics. Reflectivity >99.5% at design wavelength.

Broadband AR

BBAR coatings for wide spectral range applications. Low reflection across 400-700nm or other bands.

Laser Line Coatings

Optimized for specific laser wavelengths: 266nm, 355nm, 532nm, 1064nm, 10.6µm, etc.

Custom Coating

Custom coating designs for unique wavelength ranges, angles of incidence, and polarization requirements.

Engineering Considerations

Wavelength Selection

Material and coating selection must be matched to your operating wavelength band. We can help optimize for single-wavelength or broadband use.

Tolerance Budget

Surface quality, flatness, and centration tolerances directly impact cost. Our engineers can help balance performance requirements with manufacturability.

Thermal Considerations

High-power or wide temperature range applications require careful material selection to minimize thermal lensing and wavefront distortion.

Environmental Durability

For harsh environments, consider material chemical resistance, coating durability, and packaging options. We can provide MIL-spec testing on request.

Applications

Laser Systems

Beam focusing, collimation, and resonator optics for CW and pulsed laser systems.

Semiconductor Equipment
