The Spec Of Optical Lens : These lenses have positive focal lengths, converge incident light that form both real images and virtual images. They are widely used in telescopes, collimators, optical transceivers, magnifiers, radiometers and condensers. Paraxial focal length: ±2. Centration: 3 arc minutes. Surface figure:/4 @ 632.8 nm....
The Spec Of Optical Lens : Like plano-convex lenses, double convex lenses have positive focal lengths and form both real and virtual images. Symmetry is assured by finishing both surfaces with the same tool. Because of symmetry, aberrations including coma, distortion and lateral chromatic aberration almost exactly canceled at unit conjugate radi....
The Spec Of Optical Lens : These lenses have negative focal lengths, diverge collimated incident light, and form only virtual images which are seen through the lenses. They are often used to expand light beams or increase focal lengths in existing systems. Material: BK7. Diameter tolerance: +0.0/-0.1mm. Paraxial focal length: ±2%. Cen....
The Spec Of Optical Lens : Achromatic lenses are doublet systems consisting of one crown and one flint element, cemented together along a matching curvature, so that white light coming into the lens is all focused (imaged) at the same point on the other side of the lens. They are designed to minimize spherical and chromatic aberrations for infin....
The Spec Of Optical Lens : Ball lenses are highly polished spheres made of optically transparent homogeneous materials. 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 ease the sensitivity of translational a....
The Spec Of Optical Lens : A concave mirror, or converging mirror, has a reflecting surface that bulges inward (away from the incident light). Concave mirrors reflect light inward to one focal point, therefore they are used to focus light. Unlike convex mirrors, concave mirrors show different image types depending on the distance between the obj....
The Spec Of Optical Lens : Dispersive prisms are used to break up light into its constituent spectral colors because the refractive index depends on frequency; the white light entering the prism is a mixture of different frequencies, each of which gets bent slightly differently. Blue light is slowed down more than red light and will therefore be....
The Spec Of Optical Lens : 1. COT developed many optical components in infra ray and ultra violate wavelength range including: Silica, Silicon, Germanium, Sapphire, CaF2, MgF2, ZnS, ZnSe, etc.
2. Though those materials often owned extremely high or low hardness coefficient, many material fabrication precision had been obvious improved by new ma....

The Spec Of Optical Lens : A lens having two spherically curved faces, one convex and the other concave, so that it has the form of a shell. A positive meniscus lens is thicker in the middle than at the edges and serves as a converging lens; a negative meniscus lens thickens toward the edges and works as a diverging lens. Very large telescopes m....
The Spec Of Optical Lens : Aspheric lenses are any lenses whose surface angles and profiles are neither part of a sphere nor part of a cylinder. Conventional or non-aspheric lenses have the same curve across their entire surface, like a ping-pong ball. Aspheric lenses accomplish the same amount of refraction but are flatter and slimmer.
Aspher....
The Spec Of Optical Lens : Cylindrical lenses have at least one surface that is formed like a portion of a cylinder. Cylindrical lenses are used to correct astigmatism in the eye, and, in rangefinders, to produce astigmatism, stretching a point of light into a line. Some styles of cylindrical lenses have antireflective coatings to increase the t....
The Spec Of Optical Lens : Condenser lenses concentrate light into a projected beam. Used in projectors, enlargers, spotlights, and photo cell systems, they are usually mounted in pairs so that their convex surfaces are nearly in contact. Paraxial focal length: ±2.
Centration: 3 arc minutes.
Surface figure:/4 @ 632.8 nm.

The Spec Of Optical Lens : Fresnel lenses are flat rather than thick in the center and can be stamped out in a mold. Fresnel lenses are commonly used on spotlights. Lamps equipped with this lens are called Fresnels. Fresnel lenses can be positive or negative. A positive lens is a Fresnel lens with a positive focal length. Negative lenses are Fr....
The Spec Of Optical Lens : Micro lenses are small lenses, generally with diameters less than a millimetre (mm) and often as small as 10 micrometres (μm). The small sizes of the lenses mean that a simple design can give good optical quality but sometimes unwanted effects arise due to optical diffraction at the small features. A typical micro....

The Spec Of Optical Lens : Flat mirrors are smooth, highly polished, flat surfaces, for reflecting light. The actual reflecting surface is usually a thin coating of silver, aluminum, or other material. Most flat mirrors are coated, and then overcoated a second time to add a level of scratch resistance. Flat mirrors are found in a wide range of o....
The Spec Of Optical Lens : A convex mirror, fish eye mirror or diverging mirror, is a curved mirror in which the reflective surface bulges toward the light source. Convex mirrors reflect light outwards, therefore they are not used to focus light. Such mirrors always form a virtual image, since the focus F and the centre of curvature 2F are both ....
