  Micro Optics Optical micro lenses generally refer to optical lenses with smaller geometric dimensions, and their outer diameter can reach about 0.5mm. Commonly used optical micro lenses include sub-focusing lenses, seek lenses and round rod lenses. Optical micro lenses are widely used in various devices of optical fiber communication systems; they are very important components. Based on various performance characteristics of micro lenses, they can improve the technical level of optical fiber collimators and have very important practical value.   As a professional custom lens manufacturer , brd optical   has high-quality custom optical lenses   for sale.

  Ecoptik provides meniscus lens in both positive and negative focal lengths. These meniscus lenses are useful when used with another lenses to increase or decrease the focal length. This meniscus lens element configuration does not introduce any additional coma or spherical aberrations   W hat is positive meniscus lens Description Of positive vs negative meniscus lens Ecoptik  (also known as BRD Optical) provides meniscus lens in both positive and negative focal lengths. On the aspect of shape, it can be divided into convex meniscus lens and concave meniscus lens. On the aspect of the effect, it can be divided into diverging and converging meniscus lens.   Positive Meniscus Lens A positive lens consists of two curved surfaces with similar radii of curvature and has a positive focal length. diverging meniscus lens are typically used for related applications such as reducing the focal length of another lens, increasing the numerical aperture, etc.In order to reduce sp...
