Optical Mirror


Optical Mirror is used to redirect light in various applications including spectroscopy, material processing, medical, beam guiding and laser cavity, or alignment applications in UV, VIS, and IR spectral regions. Wavelength Opto-Electronic offers broadband, narrowband, metal, medical laser, ultrafast, scanning, phase retarder, cavity and CO₂ mirrors of flat, wedged, or curved surfaces designed for 0° or 45° of the angle of incidence with robust dielectric, reflective and metal coatings. We also provide optical mirror optimized with high reflectivity and high damage thresholds for most demanding applications and custom optical mirrors can be made to your specific design.

Scanning mirror is lightweight rectangular mirrors used for high-speed two-axis laser scanning systems. The dimensions for each mirror are calculated accordingly with the laser beam size. The mirror is designed with a high reflectivity of 99.5% or above. The scanning mirror is generally mounted onto a galvanometer for scanning purposes. For two axis scan mirrors, commonly the Y mirror has a bigger size compared to the X mirror. This is due to the fact that the X mirror is used to scan the Y mirror rather than the object directly.

Broadband Mirror is available in three different spectral ranges Visible, NIR and IR regions.  Its primary purpose is to redirect light to make optical systems compact in size. These are utilized in beam guiding with broadband reflection demanding applications in Visible, NIR, and IR ranges. Wavelength Opto-Electronic offers Broadband Mirrors with a high degree of surface flatness, low scattering, and high reflectivity. Customization options are available.

Cavity optics consist of Rear Mirror and Front Mirror (also called Output Coupler or Partial Reflector). Rear Mirrors, typically Ge or ZnSe, with very high reflectivity (>99.7%) are key optical components in the laser resonator. Output Couplers are partially reflective mirrors to extract a portion of the laser beam from the laser resonator. They often require a slight wedge to prevent interference from multiple reflections inside the component.

Metal Mirror has a thin layer of a metal coating to provide an abrasion-resistant surface while maintaining performance. These are best suited for broadband reflection requiring applications. Due to the oxidation property of Silver, these mirrors are much suitable in the low-humid environment. Wavelength Opto-Electronic offers Metal Mirrors in two protective coatings (Aluminium and Silver) with high surface quality and flatness and also open to custom requests.

Parabolic Mirrors are used to direct and focus all the incoming collimated light into a single focal point due to the surface shape parabola.  It’s applicable when there is a need to either collimate or focus the beam and when the beam divergence is small.  There are useful for telescopes, retroreflectors, fiber collimators, spectroscopy, lighting and solar applications.

Our Diamond Turning manufacturing capabilities allow us to provide off-axis Parabolic Mirrors with different surface roughness, coatings and off-axis angle specifications.  Customized Parabolic Mirror is available upon request.

Description (90° Phase Retarder 90RSI/90RCU)

90˚ phase retarders are used to convert linear polarization to circular polarization. Circular polarization means an equal amount of s-pol and p-pol for any beam orientation. With 90˚ phase retarders used in cutting, the material can be removed uniformly regardless of cutting directions.

Description (Zero Phase Retarder 0RSI/0RCU)
Reflective Phase Retarders are used as beam bending mirrors external to the laser cavity to establish and maintain circular polarization. This requirement is particularly vital for laser material processing applications where cut or scribed edge quality, and weld penetration, are critical to the consistency and precision of the final part. Zero degree phase retarders maintain control over the circularly polarized beam.

Ultrafast Mirrors Diagram 2 Ultrafast Mirrors Diagram

Ultrafast Mirror has high laser-induced damage thresholds, greater reflectance, and low Group Delay Dispersion (GDD) effects on the ultrashort pulses. These are utilized in the beam steering applications with Ti:Sapphire, Yb:YAG, Yb:KGW and Er:Fiber laser fundamental wavelengths as well as their harmonics. These mirrors are used in various fields including spectroscopy, material processing, and medical industry. Wavelength Opto-Electronic offers Ultrafast Mirrors in UV, Visible, and NIR regions with custom-mirror options required by the customer.
