Chinese wholesale Clear Lens Cover - 10W-100W Glass LED lens 80MM Focusing optical glass lens, high power LED convex lens – DG
Optical Windows An achromatic lens or achromat is a lens that is designed to limit the effects of chromatic and spherical aberration. Achromatic lenses are corrected to bring two wavelengths (typically red and blue) into focus on the same plane. The most common type of achromat is the achromatic doublet, which is composed of two individual lenses made from glasses with different amounts of dispersion. Typically, one element is a negative (concave) element made out of flint glass such as... -
Chinese wholesale Znse Meniscus Lens - Optical Glass Bk7 K9 Cylindrical Rods Lens for Optical Equipment – DG
Optical Windows A rod lens is a cylindrical lens which has the geometrical form of a cylinder and has a polished mantle, while the two flat end surfaces may be ground. It is analogous to a ball lens for focusing in both directions. Rod lenses can be used, for example, for collimating a divergent beam in one dimension (see Figure 1) or for focusing light to a line. There are also imaging applications. Note, however, that a rod lens exhibits substantial spherical aberrations when light pr... -

Professional Design Longpass Filters - windows and diffusers – DG
Windows are optical glass with ground and polished faces that are relatively parallel. They are used to isolate two physical environments while allowing light to pass, it also can be a protection of original when it’s in two physical environments. And there is almost no effect on visible light, to coat on the surface of windows could increase the transmittance, the commonly used coatings are antireflection coating (AR) and scratch-resistant coating(AS).Windows with coating can enhance ... -
Precision Polished Aspheric Lenses – DG
Small aspheric glass lenses can be made by molding, which allows cheap mass production. Due to their low cost and good performance, molded aspheres are commonly used in inexpensive consumer cameras, camera phones, and CD players.They are also commonly used for laser diode collimation, and for coupling light into and out of optical fibers. Larger aspheres are made by grinding and polishing. Lenses produced by these techniques are used in telescopes, projection TVs, missile guidance systems, an... -
Wholesale Discount Bk7 Glass Domes - high precision right angle prisms made of H-K9 and fused silica – DG
Optical Prism An optical prism is a solid, transparent optic with flat surfaces which refract light. Light enters through one surface, and may be rotated, deviated, or dispersed before leaving through another surface. These surfaces are highly polished, and the angles between them, the number of surfaces, and the position of them determine the function of the prism. Since optical prisms redirect light at a designated angle, they may be used to reflect light, to bend it within a system, t...
