Optical Lenses
- Model No:
N/A
- Product Description:
1. Lens types include plano-concave, plano-convex, biconvex, biconcave, meniscus, cemented, and cylindrical lenses.
2. They could be used on telescope, binoculars, collimator, optical transceiver, magnifier, alignment instrument, scanner, microscope...
IR Lenses And UV Lenses
- Model No:
N/A
- Product Description:
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, m...
Double-Concave (DCV) Spherical Lenses
- Model No:
N/A
- Product Description:
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.
Double-Convex Lenses (Optical Lenses)
- Model No:
N/A
- Product Description:
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 later...
Plano-convex (PCX) Spherical Lenses (Optical Lenses)
- Model No:
N/A
- Product Description:
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.
Plano-Concave (PCV) Spherical Lenses
- Model No:
N/A
- Product Description:
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.
Meniscus Lenses
- Model No:
N/A
- Product Description:
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 t...
Aspheric Lenses
- Model No:
N/A
- Product Description:
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 accompli...
Achromatic Lenses
- Model No:
N/A
- Product Description:
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 ...
Cylinder Lenses
- Model No:
N/A
- Product Description:
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 style...
Ball Lenses
- Model No:
N/A
- Product Description:
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 sp...
Condenser Lenses
- Model No:
N/A
- Product Description:
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.
Fresnel Lenses
- Model No:
N/A
- Product Description:
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 ...
Micro Lenses
- Model No:
N/A
- Product Description:
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 ...
Specialty Lenses
- Model No:
N/A
- Product Description:
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 ...
