1064nm Laser Beam Expander, High Power Magnification Beam Expanders Overview: Laser Beam Expander is used to compress the divergence angle of the beam by expanding the diameter of the laser beam, so it is widely used in laser ranging system or laser focus system. The beam through a laser beam expander features a smaller divergence angle, which can achieve the ideal effect in long distance measurement, and also can get smaller and higher energy beam spot in the laser

Axicon Lens, Transform Gaussian Beams Into Bessel Beams, Ring-Shaped Beam Overview: An axicon, also known as a rotationally symmetric prism, is a lens that features one conical surface and one plano surface. When converting a collimated beam into a ring, the plano side of the axicon should face the collimated source. When used with a collimated Gaussian beam, Axicon lenses create an approximation of a Bessel beam. Although the ring diameter increases and decreases proportiona

Glass Dome Lens For Underwater Photograph Overview: Domes make it better underwater Domes help correct for aberrations that occur in water photography because light changes speed as it passes through water rather than air. Domes provide better results than flat ports, especially for split (half up, half down) lenses, and make it easier to obtain separation, as well as more "spectacular" separation. While dome ports don't take anything away from your above-water work, their

BK7 Rod Lens, Collimating And Focusing Rod Lens Overview: A rod lens is a cylindrical lens which has the geometrical form of a cylinder with polished on the circumference and ground on both ends. Optical performance is similar to a cylinder lens. Rod lenses can be used, for example, for collimating a divergent beam in one dimension or for focusing light to a line. There are also half-rod lenses, which are rod lenses cut into two equal pieces. Rod lenses are available with

BK7 Ball Lens, Fiber Coupling Spheres Or Collimating Lens Overview: A special form of a thick biconvex optical lens is a ball lens, usually having the geometrical form of a ball (sphere). They are manufactured from a single material, usually an optical glass with good transparency in the wavelength region of interest. A frequently used material is fused silica. Ball lenses and can focus or collimate light, depending upon the geometry of the input source. They are great

UV Fused Silica Half Ball Lens, Fiber Coupling Spheres Or Collimating Lens Overview: The hemispheres of the Half-ball lenses have uniform light dispersion and are commonly used in light collimation/coupling for optical fibers. Our half-ball lenses are made from BK7, B270, Fused Silica, Sapphire. We can also deliver custom Half-Ball lenses and alternative materials in a range of diameters. General Specifications of UV Fused Silica Half Ball Lens: Material UV Fused Silica

532nm Laser Beam Expander, High Power Magnification Beam Expanders Overview: A Laser Beam Expander will increase the input laser beam by a specific expansion power while decreasing the divergence by the same expansion power, resulting in a smaller collimated beam at a large distance. Laser beam expanders can also be used in reverse to reduce beam diameter rather than expanding it. Star Optic offers Beam Expanders can expand or reduce the diameter of a collimated beam by a

355nm Laser Beam Expander, High Power Magnification Beam Expanders Overview: Laser Beam Expander are optical devices which increases the diameter of the input beam to produce a larger output, but they not only increase the diameter of a collimated laser beam, they also decrease beam divergence. Used with collimated light, they have important applications in remote sensing, interferometry, and laser scanning. A beam expander consists of two lenses. First, the beam is diverged
