Optical zoom lens for smartphone
UV Fused Silica Biconcave Lenses With two concave surfaces, biconcave lenses have negative focal length, causing collimated incident light to diverge. and they are ideal for expanding the focal length of an optical system. Bena’s biconcave lenses are offered with various materials, including UV Fused silica, ZnSe,...
Optical lens manufacturing jobs
We supply a range of Multiple anti-reflection coating options are available for the Ultraviolet (UV), visible, or Infrared (IR). N-BK7 windows are made of N-BK7, a borosilicate crown optical glass, which is designed by SCHOTT. H-K9L is the equivalent material of N-BK7 from CDGM, which is the largest supplier of...
Optical lens laboratory optical
Custom shapes, such as square windows, step windows round windows and so on. Fused silica is an excellent optical material, with low thermal expansion, exhibits more shock resistance, high laser damage threshold and good chemical homogeneity. There are have UV Fused Silica and IR Fused Silica, UV Fused Silica contains...
Protected alumimum coating mirrors
45° Rod Mirrors are designed for use in different laser and imaging systems. Bena offers the 45° Rod Mirrors with coated and uncoated versions to bend image paths or redirect laser light at 90°. Technical Specifications for Customized Rod Mirrors Customization Build-to-print
The wedge angle of wedge prism (fine annealed K9 optical glass) and antireflection film on the back can reduce the ghost image interference reflected on the back surface. High precision substrate ensures the accuracy of reflected and transmitted light wavefront. We provide a variety of wedge prisms and antireflective...
Optical geometry prism optical
Precision wedge prism By selecting the appropriate wedge, it is easy to create beam deviations without affecting other beam parameters. By selecting the appropriate wedge, it is easy to create beam deviations without affecting other beam parameters. If two wedges are used close to the inclined surface, a continuous...
Concave lens is used to correct
The principle of geometric drawing of biconcave lens imaging is the same as that of convex lens. The top of the object is also regarded as two straight lines: one is parallel to the main optical axis, deflects into divergent light after passing through the biconcave lens, and returns the refracted light to the main...
When used in light sparse medium, it can diverge the incident beam, so it is also called divergent lens. It is also called negative lens because its focal length is negative. For thin concave lens, the imaging formula, transverse magnification formula and sign rule are the same as those for convex lens. The image...
