Filters are designed by their manufacturers to transmit or absorb different wavelengths of light. And they are widely used in scientific experiments and industrial applications where that change is ne

Spherical Ball Lenses are commonly used for laser collimating and focusing, laser-to-fiber coupling, fiber-to-fiber coupling, and fiber-to-detector coupling. Larger spheres are easier to handle and ea

 Waveplates (retardation plates or phase shifters) are made from materials which exhibit birefringence. The velocites of the extraordinary and ordinary rays through the birefringent material vari

Plano-Convex Lens is widely use in optical display systems, projection optics systems, imagining optical systems, and laser measurement systems. It is best use where conjugate point-- object distance,

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 an

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

Nd:YVO4 crystal is one of the most excellent laser host materials, it is suitable for diode laser-pumped solid state laser. The crystal has these main features: low lasing threshold, high slope effici
