The manufacturing process for an optical mirror typically begins with a sheet of glass or plastic. The primary purpose of an optical mirror is the reflection of light, but that isn’t all it does. Zero degree phase retarders maintain control over the circularly polarized beam. ©2020 Newport Corporation. Front surface optical mirrors, also known as first surface mirrors, are precision polished and coated to reflect light of specific wavelength(s). Optical mirrors consist of metallic or dielectric films deposited directly on a substrate such as glass, differing from common mirrors, which are coated on the back surface of the glass. SpecificationDiameter Tolerance: +0/-0.13mmThickness Tolerance: ±0.25mmParallelism: < 3 arc min.Clear Aperture: >90%Surface Flatness: λ/4 per 1″Dia@632.8nmSurface Quality: 40-20 S-D. Metal Mirror has a thin layer of a metal coating to provide an abrasion-resistant surface while maintaining performance. Curved mirror surfaces (also called concave reflectors) can be exploited with the goal of collecting, focusing, and imaging light as illustrated in Figure 2. Rear Mirrors, typically ZnSe, with very high reflectivity (>99.7%) are key optical components in laser resonator. Furthermore, there is a wavelength-dependence (or dispersion) associated with the index of refraction. If the mirror needs a specific shape, it is usually formed while it is still a sheet to prevent damage to the reflective surface. Any different wavelength laser lines and different angles of incidence are provided upon request. For an optical mirror to perform as expected having a good understanding of your application, as well as specifying the correct optical characteristics, is essential to reducing costs and procuring the perfect mirror. As a consequence, the reflective surface of an optical mirror may be subject to environmental conditions. They appear in small laboratory experimental set-ups, industrial applications, as well as large-scale optical systems. Login to view your complete order history. A good mirror will have a noticeable thickness and no variation or ghosting. People use optical mirrors for any number of reasons. These components consist of three mirror surfaces all perpendicular to one another. 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. λ/10, over the entire usable area of the mirror. These are utilized in beam guiding with broadband reflection demanding applications in Visible, NIR, and IR ranges. 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. For two axis scan mirrors, commonly the Y mirror has a bigger size compared to the X mirror.

Narrowband Laser Mirror is designed with reflectivity R > 99.5% for Nd YAG laser applications. N-BK7 optical glass, but the cost of the material and ease of polishing must also be considered. 20-10, with a lower value indicating improved quality and therefore lower scattering. In addition, a set of properly-aligned mirrors can split visible light into two different directions. SpecificationDiameter Tolerance: +0/-0.13mmThickness Tolerance: ±0.25mmParallelism: ≤3 arc minClear Aperture: >90%Surface Flatness: λ/4 per 1” Dia @ 632.8nmSurface Quality: 40-20 S-DAngle of Incidence: 45°. Mirrors made up of planar surfaces, such as that shown in Figure 1, are important components for directing light through the proper path in an optical system. An optical mirror is a mirror type used to reflect visible light in optical devices such as cameras and telescopes. Mirrors with specific light-reflective properties, such as those used for scientific experimentation, are coated with any number of other chemicals, each with its own individual properties. SpecificationMaterial: BK7 or Fused SilicaDimension Tolerance: +0.0/-0.2mmThickness Tolerance: ±0.2mmSurface Quality: 20/10 S-DClear Aperture: >90%Angle of Incidence: 45°Flatness:  < λ/10 @ 632.8nmProtected Aluminium: Ravg>90% @ 400nm-2µmProtected Silver: Ravg>97% @ 400nm-2µmDamage Threshold: >1 J/cm², 20ns, 20Hz, @1064nm. Ultrafast Mirror has high laser-induced damage thresholds, greater reflectance, and low Group Delay Dispersion (GDD) effects on the ultrashort pulses. The reason for this is that reflection occurs at the surface of these optics, rather than passing through the optic as is the case with a lens, and so the dispersion of the index of refraction does not come into play. In addition to stationary mirrors, rapid redirection can be achieved by utilizing rotating planar mirror systems such as those found in scanners or on a smaller scale with micromirrors, which are used for switching in telecommunications and displays. They often require a slight wedge to prevent interference from multiple reflections inside the component. 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. An optical mirror is a mirror type used to reflect visible light in optical devices such as cameras and telescopes. Rear Mirrors, typically Ge or ZnSe, with very high reflectivity (>99.7%) are key optical components in the laser resonator. Consequently. CO2 Laser cavity optics consist of Rear mirror and Front mirror ( also called Output coupler or Partial reflector ). These same parameters and procedures are used to assess the quality and flatness of other optical components such as lenses or windows. Glass is generally the preferred base material, but certain applications require a denser or more heat-resistant material, so plastic is used instead. Wavelength Opto-Electronic offers Broadband Mirrors with a high degree of surface flatness, low scattering, and high reflectivity. SpecificationDiameter Tolerance: +0/-0.13mmThickness Tolerence: ±0.25mmCentration: < 3 arc minutesClear Aperture: >90%Surface Quality: 40-20 S-DAngle of Incidence: 0 degrees. 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. These mirrors are also common in areas where an infinite space is needed for a light beam; two mirrors may be set up parallel to one another so the light may bounce back and forth forever.

Enter your email address below to reset your account password. This is due to the fact that the X mirror is used to scan the Y mirror rather than the object directly. With 90˚ phase retarders used in cutting, the material can be removed uniformly regardless of cutting directions. The scanning mirror is generally mounted onto a galvanometer for scanning purposes. Mirrors are arguably the most commonly-used optical components. If a small item is touched to the glass, such as a fingertip or the end of and unsharpened pencil, the reflection will show the overall quality of the surface.
