fused silica. DescriptionReflective laser optics mirrors must have low reflection losses, high optical quality, and good resistance against extreme optical intensity. Such mirrors can be combined to form optical components known as retroreflectors or corner cubes. These mirrors are used in various fields including spectroscopy, material processing, and medical industry. The distance between the actual and reflected image shows the depth of the glass; a ghost image indicates that the pane is likely made of plastic or poor-quality glass, and any variation in color indicates a poor reflective coating. The manufacturing process for an optical mirror typically begins with a sheet of glass or plastic. Curved mirror surfaces (also called concave reflectors) can be exploited with the goal of collecting, focusing, and imaging light as illustrated in Figure 2. This is measured using either a test plate or an interferometer. Simple spherical reflectors can be used to collect radiation from a source at the focal point (located at half of the radius of curvature of the mirror) and reflect it as a collimated beam parallel to the axis. For two axis scan mirrors, commonly the Y mirror has a bigger size compared to the X mirror. However, for transmissive mirrors, a substrate material with a homogenous index of refraction is important, e.g. Surface flatness is often specified in wavelengths, e.g. OPTICAL | MIRROR SIBU|DESIGN_1019_100_EN EN SIBU DESIGN GmbH & CoKG Jupiterstraße 8 l 4452 Ternberg l Austria l Tel: +43 (0) 7256.6025.0 Fax: +43 (0) 7256.7020 l E-mail: info@sibu.at l www.sibu.at . Output Couplers are partially reflective mirrors to extract a portion of the laser beam from the laser resonator. Certain materials have lower thermal expansion coefficients, e.g., PYREX® borosilicate glass or fused silica, than others, e.g. 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. 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. Enter your email address below to reset your account password. Furthermore, there is a wavelength-dependence (or dispersion) associated with the index of refraction. They appear in small laboratory experimental set-ups, industrial applications, as well as large-scale optical systems. Rear Mirrors, typically ZnSe, with very high reflectivity (>99.7%) are key optical components in laser resonator. Wavelength Opto-Electronic offers Ultrafast Mirrors in UV, Visible, and NIR regions with custom-mirror options required by the customer. They are also used in nearly any laser-based device, from the common laser pointer all the way to military-targeting systems. Most substrates upon which the coatings are deposited are dielectric materials and these substrates control the thermal expansion and transmission properties of mirrors. N-BK7 optical glass, but the cost of the material and ease of polishing must also be considered. Any different wavelength laser lines and different angles of incidence are provided upon request.

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 … A good mirror will have a noticeable thickness and no variation or ghosting. These mirrors have a higher damage threshold, high optical quality, and are suitable for beam-guiding applications. Front surface optical mirrors, also known as first surface mirrors, are precision polished and coated to reflect light of specific wavelength(s). λ/10, over the entire usable area of the mirror. Provide an order number and postal code to check the status of an order or download an invoice for an order that has shipped. The dimensions for each mirror are calculated accordingly with the laser beam size. These instruments typically use an optical mirror to filter out the harmful effects of the reflected light or to send the viewed light to both an eyepiece and a work instrument without distortion.
