  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 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 E coptik co., ltd.  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 spherical aberration of the plano concave lenses is negative   Specifications Of Plano Concave Lens   As a concave lens company , concave lens factory , we will do our best to meet all the needs of customers.   There...

  A plano concave cylindrical lens  is used to expand light in on-axis. A negative cylindrical lens is able to diverge collimated input light away from a line. Plano   cylindrical lenses are used for  one-dimensional compression of images, anamorphic beam shaping, and laser line generation.   If you have the demand, please feel free to contact Ecoptik.   Descriptions Of Plano Concave C ylindrical L ens D esign   The plano   cylindrical concave lens  forms a divergent linear virtual image, which is used to control the size of the beam in one direction. The material of this lens is BK7, so it is not suitable for ultraviolet wavelengths.   The plano cylindrical lens is used in  laser scanners, spectrometers, dye lasers, acousto-optics, optical processors, and other similar applications.   As a cylindrical lens supplier , w e use high-quality optical glass classical optics grinding, polishing processing techniques, surface accuracy...

  Pentagonal prism is the beam Angle (90 °), one of the steering gear.It has two purposes: one is that no matter how much the first incident Angle on the side is the emergent light incident light steering Angle (90 °);The other is that, unlike a rectangular prism, the resulting image has neither rotation nor specular reflection.   P entaprism   is commonly used in camera viewfinders, image observation systems or measuring instruments.   Description Of Penta Prism   Characteristics of roof pentaprism  is a 90° Angle of the light became a vertical incidence, and then after the 45 ° Angle of two surface reflection, from the Angle of 90 ° exit, on the other side of the incident light and emergent light is equal to 90 ° Angle, such application pentagonal prism can turn axis around 90 °. Recently, the use of the characteristics of a pentagonal optical prism measurement [1] the planarity of the Pacific Ocean, namely the pentagonal prism rotates around the horizont...

  The "spherical curvature" of a spherical lens  is constant, meaning that the front and back surfaces of the lens are part of the spherical surface, respectively. Each surface may be convex (protruding from the lens), concave (concave into the lens), or "flat" (flat). The line between the spherical centre points on the front and rear surfaces of the lens is called the optical axis of the lens. In almost all cases, the optical axis of the lens passes through the physical centre of the lens. Ecoptik  can provide different kinds of spherical lenses  like plano concave lens, plano convex lens, achromatic lens.   The lens can be widely used in security, vehicle, digital camera, laser, optical instruments and other fields. With the continuous development of the market, lens technology is more and more widely used. As a precision optical company , Ecoptik has obtained the high technology of producing lenses. If any issues, please contact us.   The radius of curva...
