Optical Fused Silica and Sapphire Cylinder Rod Lens
A Rod lens is a special type of cylinder lens, and is highly polished on the circumference and ground on both ends. Rod lenses perform in a manner analogous to a standard cylinder lens, and can be used in beam shaping and to focus collimated light into a line. -
High precision aspherical glass lens by molding
The most notable benefit of aspheric lenses is their ability to correct for spherical aberration, an optical effect which causes incident light rays to focus at different points when forming an image, creating a blur. Spherical aberration is commonly seen in spherical lenses, such as plano-convex or double-convex lens shapes, but aspheric lenses focus light to a small point, creating comparatively no blur and improving image quality. -
infrared optical glass dome lens with coating
Domes are ideal for underwater and split-level (half over/under) photography, because they correct for aberrations that occur as light travels at different speeds above and below water. Outex ports, including domes, are made of optical glass.

Optical Mirrors are designed to reflect light for a variety of applications, including beam steering, interferometry, imaging, or illumination. Optical Mirrors are used in a wide range of industries, such as life sciences, astronomy, metrology, semiconductor, or solar. -
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.

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. -
Optical Bk7 Glass Diameter 1-2.5mm Polished Quartz Ball Lens
Ball lenses are, as the name suggests, completely spherical lenses most commonly used to couple light in and out of fibers. We can supply ball lens in a range of alternative materials and diameters. We are able to supply high precision grade 3 ball lenses, mid-range grade 25 ball lenses and commercial grade 100 ball lenses offering all grades to suit any application. Aside from fiber coupling applications, ball lenses are also used as objective lenses in endoscopy, laser measurement systems and bar-code scanning. Our half ball lenses offer uniform dispersion of light and typically used in LED displays and LED traffic lights. Ball lenses are used particularly as beam collimators for optical fibers (fiber collimators) and for fiber-to-fiber coupling. They are also suitable for miniature optics with applications like barcode scanning, as objective lenses in endoscopy and for optical sensors. There are also microscope objectives (particularly immersion objectives) which have a hyper hemisphere (e.g., somewhat more than a hemisphere) as the first lens. DG can provide ball lenses and half ball lenses made from various substrate materials including sapphire, ruby, BK7, UV fused silica, high index glass, and germanium, ZnSe, ZnS with AR coating. Our ball lenses and half ball lenses are ideal for applications such as fiber communications, endoscopy and microscopy. Available diameters are between 0.3 mm to 100 mm, with diameter tolerance (sphericity) <0.4 µm and surface roughness (Ra) <0.007 µm. Custom ball and half ball module options are also available on request. Material options include: quartz (260–2500 nm), sapphire (0.17–5.5 μm), ruby (250 nm to NIR), BK7 (or equivalent) (250–2500 nm), UV-grade fused silica (170–2500 nm), as well as B270 (320–2600 nm) and borosilicate (or equivalent) (310–2700 nm) material options.

Optical Glass Bk7 K9 Beamsplitter Cube For Laser And Optical Instruments
Beamsplitters are optical components used to split incident light at a designated ratio into two separate beams. Additionally, beamsplitters can be used in reverse to combine two different beams into a single one. Beamsplitters are often classified according to their construction: A beamsplitter is an optical component used to split a beam of incident light into two parts in a laser or illumination system. Cube beamsplitters consist of a pair of precision right-angle prisms carefully cemented or optically contacted together. The hypotenuse of one of the prisms is coated with polarizing or non-polarizing beamsplitter coating and four sides of the cube are AR coated to minimize surface reflection losses. Plate beamsplitters feature a coated front surface that determines the beamsplitting ratio, while the wedged back surface is AR coated to minimize ghosting. Dichroic beamsplitters are wavelength dependent and are used to combine or split laser beams in a variety of colors. Laser beam attenuators provide high resolution intensity control without introducing a gradient in the intensity distribution or a change in the beam propagation direction. -
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. -
