  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 scanning reflection imaging.

Filter

  Filter 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. Ecoptik  as a professional optical filters ltd , offers different types of custom optic c al filters , such as optical comb filte

USAF 1951 resolution test targets/chart

  First of all, we talk about the resolution target, which is classified on the official website of famous brand as a kind of measuring plate.   But what we're talking about today is the USAF 1951 resolution chart.   The product is a kind of calibration chart, which is designed and manufactured according to the US military standard MIL-STD-150A.Its different resolution units use corresponding groups and element markers, and the corresponding resolution of each unit can be obtained by looking up the table. It has a wide range of applications, from the complex optical systems of aviation, aerospace and astronomical telescopes to the manufacturing and production of precision optical products  commonly used in daily life. It is not only suitable for the imaging quality evaluation of various optical instruments and equipment ( such as stereo microscope, collimator and telescope, etc. ), but also very suitable for the imaging quality evaluation of various lenses and custom optical compon
