  Aspheric lenses can improve image quality and correct imaging problems usually associated with spherical lenses. The original work and function of the aspheric lens are mainly reflected in the following aspects:   1. The spherical aberration of spherical lenses In a spherical lens, light is focused at different distances (depending on where it enters relative to the edge of the lens), which can cause blur and peripheral distortion. This phenomenon is called spherical aberration.   A spheric lenses advantages : aspherical lenses can reduce or eliminate this problem due to its unique design (with a shallower surface curvature angle). When light enters the aspheric lens, whether it enters or not, it will be focused to a point, resulting in a clearer and sharper image.   2. Distortion of spherical lens When spherical lenses zoom in or zoom out an image, they will distort and bend the lines viewed through them. Since the edge power of the aspheric lens is low, the risk of pincushion disto

  1. BRD High-performance IR lens   We BRD can provide a large number of customized infrared IR lenses and components for focusing, collimating and collecting light in the near-infrared (NIR), short-wave infrared (SWIR), mid-wave infrared (MWIR) and long-wave infrared (LWIR) spectra. By adhering to the highest manufacturing and ISO standards, we produce high-performance IR lenses that can meet all kinds of needs from customers such as industrial, medical, life science, and defense applications.   We have extensive experience in manufacturing high-quality IR lenses and infrared lens design.

With the help of advanced in

  Optical Products in Laser Optical System   Lasers have very good coherence, directivity and high concentration of energy.   The advent of the laser means that the optical element is no longer limited to the observation and recording of the original shape of the image, but the image is processed and recorded by the transformation of the time and space spectrum. In addition, in optical measurement, the use of laser precision is also higher than before.   Because the laser itself has very good coherence, when the material itself has defects, dust or bubbles, stripes, etc., it will be easy to produce noise, because the material is very strict in the selection, and in the processing process, the processing precision of the components to be very high requirements. Especially for the opposite type. Usually, it needs to be at least λ/10-λ /20 or so.   Ecoptik focuses on high precision custom machining. we have a wealth of experience in laser products.   For example, Planar optical elements,

  PARAMETER: High Reflection (HR) coatings, including high reflection dielectric coatings and Metallic coatings, provide high reflection in some wavelength range, and are widely used in laser system and other optical elements. HR coating provides more effective and efficient spectral performance due to the low absorption properties. These mirror coatings can also be further customized to provide additional high pass or low pass wavelength performance in addition to the specified reflection band   High Reflection (HR) coatings, including high reflection dielectric coatings and Metallic coatings, provide high reflection in some wavelength range, and are widely used in laser system and other optical elements.
