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... |
