Rod Lenses are highly polished small diameter rods made of optically transparent homogeneous materials. A carefully controlled manufacturing process produces rods (or fibers) with precise diameters and unsurpassed surface quality. Optical performance is similar to a cylinder lens. Collimated light passing through the diameter of the rod will be focused into a line.We supply optical rod lens,specification of our rod lens as follow:Dimension Range: 3-50mm Polish on both sides,cylindrical side or all sideDiameter tolerance:+0/-0.02mm Thickness tolerance:+/- 0.02mm Centration:90% Chamfer: 0.1-0.25mm*45 degreesCoat:as requestedMaterial:Float glass,K9 ,FS,SapphireSF11,CaF2,MgF2 or other optical glass
Wedge prism is an optical element having plane-inclined surfaces, usually the faces are inclined toward one another at very small angles. Wedges divert light toward their thicker portions.Wedge prism
A lens cover or lens cap provides protection from scratches and minor collisions for camera and camcorder lenses. Lens covers come standard with most cameras and lenses. Some mobile camera phones incl
Meniscus Lens can increase the NA of the system while only adding slightly to the total spherical aberrations. The Negative Meniscus Lens is used to increase the focal length of another lens while mai
