Daheng New Epoch Technology, Inc. Datasheets for Optical Lenses

Optical lenses are transparent components made from optical-quality materials and curved to converge or diverge transmitted rays from an object. These rays then form a real or virtual image of the object.  This area includes micro lenses.

Product Name Notes
Plano-Concave Lenses -- GCL-0103 A plano-concave lens diverges parallel input rays. It has a negative focal length. While the output rays do not actually meet to form a point, they do appear to be...
Negative Achromatic Doublets -- GCL-0107 An achromatic-doublet consists of a negative low-index(crown glass)cemented with a positive high-index(flint glass)lens. These lenses are computer-optimized for infinite conjugate ratio. While the output rays do not actually meet to...
Positive Achromatic Doublets -- GCL-0106 An achromatic-doublet consists of a positive low-index(crown glass)cemented with a negative high-index(flint glass)lens. These lenses are computer-optimized for infinite conjugate ratio. They also exhibit excellent paraxial performance, with minimal spherical...
Calcium Fluoride Plano-Convex Lenses -- GCL-0111 Calcium Fluoride has good thermal property due to its high transmission from 250nm to 7µm. It is commonly used in cooled thermal imaging systems or laser focusing. Plano-convex lenses are...
Circular Cylinder Plano-Convex Lenses -- GCL-11011 Circular Cylinder Plano-Convex
F-theta Lenses -- GCO-31 F-theta Lenses are plane field objectives, which are commonly used in combination with XY galvanometer scanner. Contrary to a normal lens which focuses a input collimated beam on a spherical...
Fused Silica Plano-Concave Lenses -- GCL-0109
Fused Silica Plano-Convex Lenses -- GCL-0108
Fused Silica is the material used in UV region and imaging applications. It has high transmission from 200nm to 2.5µm. In addition, it also can be used in higher operating...
Germanium Plano-Convex Lenses -- GCL-0131 Germanium is ideal for mid-infrared applications. It stands up well to harsh environments. It is subject to thermal runaway, which means that the transmission decreases as temperature increases. Plano-convex lenses...
Meniscus Lenses -- GCL-0105 Meniscus lenses can be either positive or negative, depending on the relative curvatures of the two surfaces. A negative meniscus lens is thinner at the center than periphery. Conversely, a...
Plano-Convex Lenses -- GCL-0101 Plano-convex lenses are mostly used for focusing parallel rays of light to a spot. The asymmetry of these lenses between the front and back surface minimizes spherical aberration effectively, particularly...
Rod Lenses -- GCL-1105 Rod Lenses are polished on the circumference and ground on both ends. It is similar to a Plano-Convex cylinder lens. Collimated light passing through the diameter of the rod will...
Cylinder Plano-Concave Lenses -- GCL-1103 Similar to a Plano-Concave lens in profile, but only as cylinder instead of a sphere, this cylindrical lens focuses light only in one as a cylinder dimension. It can be...
Cylinder Plano-Convex Lenses -- GCL-1101
Plano-Convex Cylindrical Lens -- L11-002
Similar to a Plano-Convex lens in profile, but only as a cylinder instead of a sphere, this cylindrical lens focuses light only in one dimension. It can also transform a...
Bi-Concave Lenses -- GCL-0104 Similar to plano- concave lenses, a bi-concave lens diverges parallel input rays and has a negative focal length. It has a virtual focus at the object side of the lens.
Bi-Convex Lenses -- GCL-0102 Similar to plano-convex lenses, a bi-convex lens has a positive focal length and focuses parallel rays of light to a spot. Because the front and back surface of the lens...
Achromatic Fourier Transform Lenses -- GCO-02 These air-spaced or cemented doublets are designed for application in coherent or incoherent optical systems for information processing. Spherical, coma, astigmatic and achromatic aberrations are corrected. The components can be...
Two-Tilt Achromatic Fourier Transform Two-Tilt Achromatic Foutier Transform lenses can be tilted about the Y and Z axes by two thumbscrews. The components can be mounted on post (GCM-01M and GCM-03M).
Zinc Selenide Plano-Convex Lenses -- GCL-0121 Zinc Selenide has good thermal property due to its high transmission from 600nm to 16µm. It is commonly used in cooled thermal imaging systems or laser focusing. Plano-convex lenses are...
