UV Fused Silica Biconcave Lenses
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,...
Zerodur Glass Ceramics Aspheric Lenses
Bena’s aspheric lenses are available either with or without anti-reflective coating. The surface of an aspheric lens is designed to eliminate spherical aberration in a range of applications, including imaging, laser focusing applications and bar code scanner. Bena provides aspheric lenses with different materials. In...
High Precision Optical lenses and glass
As a manufacturer of optical mirrors, we recommend that firstly choose the right material and coating material according to the environment of optical mirrors and consider whether the adhesion between optical material and coating material is feasible. For example, the adhesion of gold and silver to optical glass is...
What is optical mirror? The optical mirror realizes control beam and imaging by coating at least one side of optical substrates. Optical mirrors divide into plane mirrors and spherical mirrors. Flat mirrors are used for applications that deflect light as accurately as possible, especially for optical experiments....

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...
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...

Concave lens of the focusing iris
The line connecting the centers of curvature on both sides is called the principal axis, and the central point O is called the optical center. Light passing through the optical center does not refract no matter where it comes from. The beam parallel to the main axis refracts on the concave lens and diverges to the...
Lens is a kind of refractive optical element made of different optical materials. Its refractive surface is two spheres or one sphere. According to its shape, it can be divided into convex lens (positive lens) and concave lens (negative lens). The lens whose central part is thicker than the edge is called convex lens....
