  Front Surface Mirror Ecoptik designs and manufactures custom 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 Front Surface  Mirror   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. F ront coated mirror s are widely used for optical high fidelity scann...

  The optical glass 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 λ. Ecoptik (also known as BRD Optical) offers different types of custom optical filters , such as optical comb filters, optical high ...
