  Plane concave lens   bend parallel input rays so they diverge from one another on the output side of the lens and hence have a negative focal length. The spherical aberration of the plano concave lenses is negative and can be used to balance aberrations created by other lenses. Similar to the plano concave lens, the curvature surface usually faces the largest object distance or the infinite conjugate to minimize spherical aberration.   If you want to know more information about plano concave lens, please contact us.   Description Of Plano Concave Lens Ecoptik  Plano concave lens bend parallel input rays so they diverge from one another on the output side of the lens and hence have a negative focal length.

  The reflector, as the name suggests, was born to meet people's requirements for light reflection. It is an optical element   that uses the law of light reflection. Optical mirrors generally include spherical mirrors/reflectors, flat mirrors, and aspheric mirrors. But basically, it is through optical coating or direct selection of metal materials.   Ecoptik (also known as BRD Optical) is one of the leading optical mirrors factory  which provides custom optical mirrors, and our coated optical mirrors for sale mainly include metal (aluminum, silver, gold) coatings and dielectric coatings. It is widely used in laser systems, scanning systems, and optical measurement systems. Ecoptik (also known as BRD Optical) can provide various optical mirrors and custom optical mirrors, such as scanning mirror, AI mirror, au mirror, front surface mirror and dielectric mirror. Contact Ecoptik (also known as BRD Optical) to get more about the information, meaning, and concept of custom optical mirro

  An anamorphic prism pair is a pair of prisms which is usually used for reshaping the profile of a laser beam. For example, the elliptical beam from a laser diode can be transformed into a beam with circular cross-section, as is needed for many applications, by using an optical prism pair as a beam expander for only one direction (e.g., the horizontal one). Of course, one can also just modify the ellipticity, or convert a circular beam into an elliptical one.   Description Of Anamorphic Prism   Diode lasers usually have elliptical beam profiles. In most cases, though, the shape of the circular beam is required, such as pattern matching with the external resonator to make the beam size adapt to the small aperture through the isolator. A deformed pair of anamorphic prisms  is used to transform an elliptical laser diode beam into an approximately circular beam to amplify an elliptical beam in one dimension.   Specifications Of Anamorphic Prism   Material SF11 Dimension Tolerances +0.0, -

  Optical Prism, a transparent object surrounded by two planes that intersect but are not parallel to each other, is used to split light or disperse light beams. An optical prism is a polyhedron made of transparent materials (such as optical glass prism, optical crystal prism, etc.). It is widely used in optical instruments. Prisms can be divided into several types according to their properties and uses. For example, the "dispersion prism" that decomposes the composite light into the spectrum in a spectroscopic instrument, the more commonly used is an equilateral prism; in a periscope, binocular telescope and other instruments, the direction of light is changed to adjust its imaging position. "Reflecting prisms" generally use right-angle prisms. Ecoptik (also known as BRD Optical), a leading optical prism manufacturer , provides different types of optics/ optical prisms for sale , such as roof prism, pyramid prism /tetrahedral prism, pentaprism.   Custom Optical Pri

  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 (also known as BRD Optical) as a professional optical filters ltd , offers different types of custom optical filters, such as op

  A pyramidal prism/angular cube reflector is always used to reflect a beam of light into the prism, regardless of the direction of the beam. Corner prisms are widely used where accurate alignment is difficult.   Corner optical prism rear reflector/pyramid prism is designed to reflect any light or beam entering the prism surface, regardless of the direction of the prism, can be reflected back to itself. The mirror can only be used at a normal Angle of incidence. Therefore, corner prism retroreflector is an ideal choice for accurate alignment. They have three total internal reflections that work even at very large incident angles. N - BK7 Corner Cube Retroreflectors is made by the precision of N - BK7, suitable for all kinds of visible light.   Description Of Pyramid Optical / Tetrahedr on  Prism   A tetrahedral optical prism, also known as a pyramidal prism, consists of four planes with different spatial directions. One of the four planes is the incidence/exit plane of light, and the o

  Rhombic prisms are used to displace a beam laterally without changing its direction. They may be coated to transmit part of the beam and produce two parallel and displaced emerging beams. Can be coated to produce a polarizing beam separator. These rhombic prisms are manufactured from either BK7A or Fused Silica. They are supplied uncoated but many coating options are available.   Description Of Rhomboid Prism   Ecoptik rhomboid prisms are commonly used to displace a laser beam without changing its direction. In imaging applications, rhomboid prism will displace the optical axis without inverting the image. The lateral displacement is equal to the length of the prism. Rhombus prisms are widely used in the fields of optics, imaging, and photonics. They can be used to replace optical centerline beam folding and three-dimensional systems of different sizes. In modern life, optical rhomboid prisms are widely used in digital equipment, science and technology, medical equipment, and other f
