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. 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. Furthermore, there is a wavelength-dependence (or dispersion) associated with the index of refraction. Optical mirrors are polished prior to being coated with a reflective coating. Provide an order number and postal code to check the status of an order or download an invoice for an order that has shipped. Surface quality is usually dictated by the severity of random localized defects on the surface. They often require a slight wedge to prevent interference from multiple reflections inside the component. For high precision surfaces, such as those found within the cavity of a laser, a scratch-dig specification of 10-5 may be required since it would yield very little scattered light. Surface flatness is often specified in wavelengths, e.g. The mirror is designed with a high reflectivity of 99.5% or above. Wavelength Opto-Electronic offers Ultrafast Mirrors in UV, Visible, and NIR regions with custom-mirror options required by the customer. These mirrors possess an advantage over lenses (see Optical Lens Physics) in that they perform satisfactorily across a broad-wavelength range without requiring refocusing. Nearly all personal mirrors, such as bathroom or car mirrors, are a type of optical mirror. If light transmitted through the substrate is not required, the backside of the substrate is typically ground to prevent inadvertent transmissions. SpecificationDiameter Tolerance: +0/-0.13mmThickness Tolerence: ±0.25mmCentration: < 3 arc minutesClear Aperture: >90%Surface Quality: 40-20 S-DAngle of Incidence: 0 degrees. Rear Mirrors, typically ZnSe, with very high reflectivity (>99.7%) are key optical components in laser resonator. People use optical mirrors for any number of reasons. These mirrors are used in various fields including spectroscopy, material processing, and medical industry. This is due to the fact that the X mirror is used to scan the Y mirror rather than the object directly. Enter your email address below to reset your account password. 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. They often require a slight wedge to prevent interference from multiple reflections inside the component. 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. Surface polishing tolerances in terms of irregularity, surface roughness, and cosmetic imperfections are verified using state-of-the-art metrology equipment. Mirrors with specific reflective coating can filter out certain wavelengths of light, making the light safer to observe. Ellipsoidal surfaces can focus light from one focal point to another (see Figure 2). Historically, this was tin, mercury or silver, but today aluminum is the most commonly-used reflective substance. After the pane is properly shaped, one side of the pane is covered in a reflective substance. Circular polarization means an equal amount of s-pol and p-pol for any beam orientation. The Narrowband Mirror is available with us at fundamental line 1064nm with their harmonics 532nm, 355nm, and 266nm for 45° angle of incidence. fused silica. 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. Need help correctly specifying an optical mirror? 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. SpecificationMaterial: Fused SilicaDimension Tolerance: +0.0/-0.2mmThickness Tolerance: ±0.2mmSurface Quality: 20/10 S-DClear Aperture: >80%Reflectance: >99%Angle of Incidence: 45°Flatness: < λ/10 @ 632.8nmGroup Delay Dispersion: < 30fs² (for s & p-polarized light)Coating: HRDamage Threshold: >100mJ/cm² @ 800nm, 50fs, 50Hz. DescriptionScanning mirror is lightweight rectangular mirrors used for high-speed two-axis laser scanning systems. 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.
