Optical Glass Bk7 K9 Cylindrical Rods Lens for Optical Equipment
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. -
high precision right angle prisms made of H-K9 and fused silica
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. -

Glass Fresnel Lens Dia 150 Borosilicate Glass Optical Collimator Lens for Projector
Fresnel lens, succession of concentric rings, each consisting of an element of a simple lens, assembled in proper relationship on a flat surface to provide a short focal length. The Fresnel lens is used particularly in lighthouses and searchlights to concentrate the light into a relatively narrow beam.

Optical prisms
Optical Prisms are used to redirect light at a designated angle. Optical Prisms are ideal for ray deviation, or for adjusting the orientation of an image. An Optical Prism's design determines how light interacts with it. When light enters an Optical Prism, it either reflects off an individual surface or several surfaces before exiting, or is refracted as it travels through the substrate. -
90 Degree Glass Lens for LED High Bay Lighting
We manufacture various shapes and sizes of glass lenses for various LED applications, either own design or customized.

Bk7 Plano-Convex Glass Lens with Coating
DG Optics offers various sizes of plano-convex lens, and the lenses are available in a range of coating or substrate options. Anti-reflection coatings range from the Ultraviolet (UV) to the Infrared (IR), including UV-AR, UV-VIS, MgF2, VIS 0°, VIS-NIR, NIR I, NIR II,. Additional coatings designed specifically for laser wavelengths, such as 355nm, 532nm, or 1064nm are also offered. Germanium (Ge), Silicon (Si), or Zinc Selenide (ZnSe) substrates are ideal for Infrared (IR) applications. -
50mm Precision Polished Aspheric Lenses
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. -
Ball and half ball lenses
Ball Lenses are commonly used to improve signal quality in fiber coupling applications, or for use in endoscopy or bar code scanning applications. Ball Lenses feature short back focal lengths to minimize the distance needed from the Ball Lens to the optical fiber. DG Optics offers a variety of Ball Lenses in a range of substrates for performance in the ultraviolet to the NIR. Half-Ball Lenses are also available to ease mounting or system integration. -
Optical Sphere Dome Lens
Dome windows are hemispheres. The two optical surfaces are an equal thickness apart, creating a naturally strong shape that gets tougher under pressure. This makes dome windows ideal for underwater environments and in applications such as camera dome ports and submersible windows. -
double convex lens
Bi-Convex Lenses are the best choice where the object and image are at equal or near equal distance from the lens. When the object and image distance are equal (1:1 magnification), not only is spherical aberration minimized, but also coma, distortion, and chromatic aberration are identically canceled due to the symmetry.
