  Fused Silica IR  fused silica  glass has a high transmittance from ultraviolet to near-infrared (185nm-00nm), and has a high transmittance in the deep ultraviolet region, making it widely used in ultraviolet lasers. In addition, compared with ordinary optical glass, fused quartz glass for optics  has better uniformity and lower thermal expansion coefficient, making it particularly suitable for applications in the ultraviolet to near-infrared wavelength range, high-power lasers and imaging fields. As one of  professional fused silica suppliers , Ecoptik can provide the best fused silica, if you want to know the fused silica price, please feel free to contact us.   Fused Silica Descriptions As a major optical product material, the main characteristics of fused silica are:   High purity and corrosion resistance   High softening temperature, strong heat resistance   Low thermal expansion coefficient, thermal shock resistance   From the ult...

  Front Surface Mirror E coptik co., ltd.  designs and manufactures optical mirrors with high reflectance, which can double the output power of the laser; it is reflected by the first reflecting surface, the reflected image is not distorted, and there is no ghosting.   Description Of F ront S urfaced M irror   The Ecoptik mirror with high reflectance can double the output power of the laser; it is reflected by the first reflecting surface, the reflected image is not distorted, and there is no ghosting, which is the reflection of the front surface. If a common optical mirror is used as the second reflecting surface, not only the reflectance is low, but also the wavelength is not selective, and ghosting is likely to occur. With the front coated film mirror, the obtained image is not only high in brightness, but also accurate and unbiased, the picture quality is clearer and the color is more realistic. Front surface mirrors  are widely used for optical high fidelit...

  The custom optical filter  is an optical device used to select the desired radiation band. One of the common characteristics of filters is that there is no filter to make the image of celestial bodies brighter, because all filters absorb certain wavelengths, which makes the object darker. Its main feature is that the size can be made quite large. Thin film filters generally transmit longer wavelengths and are mostly used as infrared filters. The latter is to form a certain thickness of high refractive index or low refractive index metal-dielectric-metal film or all-dielectric film alternately on a certain substrate by vacuum coating, forming a low-order, multi-stage tandem solid method Brie-Perot interferometer. The choice of film material, thickness and series connection mode is determined by the required center wavelength and transmission bandwidth. Ecoptik  as a professional   optical filters ltd, offers different types of custom optical filters , such as optica...

  Micro Optics Optical micro lenses generally refer to optical lenses with smaller geometric dimensions, and their outer diameter can reach about 0.5mm. Commonly used optical micro lenses include sub-focusing lenses, seek lenses and round rod lenses. Optical micro lenses are widely used in various devices of optical fiber communication systems; they are very important components. Based on various performance characteristics of micro lenses, they can improve the technical level of optical fiber collimators and have very important practical value.   As a professional custom lens manufacturer , brd optical   has high-quality custom optical lenses   for sale. Welcome to contact us if needed.

  Ecoptik provides meniscus lens in both positive and negative focal lengths. These meniscus lenses are useful when used with another lenses to increase or decrease the focal length. This meniscus lens element configuration does not introduce any additional coma or spherical aberrations   W hat is positive meniscus lens Description Of positive vs negative meniscus lens Ecoptik  (also known as BRD Optical) provides meniscus lens in both positive and negative focal lengths. On the aspect of shape, it can be divided into convex meniscus lens and concave meniscus lens. On the aspect of the effect, it can be divided into diverging and converging meniscus lens.   Positive Meniscus Lens A positive lens consists of two curved surfaces with similar radii of curvature and has a positive focal length. diverging meniscus lens are typically used for related applications such as reducing the focal length of another lens, increasing the numerical aperture, etc.In order to reduce sp...
