245281. Optical Glass Bk7 Negative Lens 
[Jan 27, 2023]
[Jan 27, 2023] Double convex lenses have two outward curved surfaces, normally the two surfaces have same radius of curvature, with finely polished. Bi convex lenses have positive focal length, so they are used for 1:1 imaging and in ...
245282. Germanium Glass Optical Window IR Window Ge Window [Jan 27, 2023]
[Jan 27, 2023] Optical windows are used to isolate different physical enviroments while allowing light to pass. The selection of a window should consider the properties of the different optical materials, transmission, wavelength ...
245283. China Double Concave Lens Manufacturer [Jan 27, 2023]
[Jan 27, 2023] Double concave lenses have equal radius of curvature on both surfaces. The lenses are often used to expand light beams or to increase focal lengths in optical systems and devices, and biconcave lenses are also used in ...
245284. Plano Concave Lens for Beam Expander [Jan 27, 2023]
[Jan 27, 2023] Plano-concave lenses are thicker at the edge than in the center and flat on another surface. Plano concave lens (PCV) has negative focal length. So the lenses are used to bend parallel input rays so they can diverge ...
245285. Magnifier Plano Convex Lens Custom Made [Jan 27, 2023]
[Jan 27, 2023] Plano convex lenses are designed to focus and collimate the light in optical system. The lenses are often used for laser, fiber, medical, sensor, communication and surveying instruments. Plano convex lenses are offered ...
245286. Cylindrical Lens with Optical Glass Bk7/Jgs1 [Jan 27, 2023]
[Jan 27, 2023] A cylindrical lens is a lens which focuses light into a line instead of a point, as a spherical lens would. The curved surface or surfaces of a cylindrical lens are sections of a cylinder. And focus the image passing ...
245287. Optical Glass Plano Concave Lens [Jan 27, 2023]
[Jan 27, 2023] Plano concave lenses are flat on one side and have concave surface for another side. The lenses are designed for parallel light to be incident to the concave surface. So the plano concave lenses are used for ...
245288. Germanium Optical Window-Ge Window-Glass Window [Jan 27, 2023]
[Jan 27, 2023] Optical windows are used to isolate different physical enviroments while allowing light to pass. The selection of a window should consider the properties of the different optical materials, transmission, wavelength ...
245289. Double Concave Lens for Beamexpander [Jan 27, 2023]
[Jan 27, 2023] Double concave lenses have equal radius of curvature on both surfaces. The lenses are often used to expand light beams or to increase focal lengths in optical systems and devices, and biconcave lenses are also used in ...
245290. Factory Offer Double Convex Lens [Jan 27, 2023]
[Jan 27, 2023] Double convex lenses have two outward curved surfaces, normally the two surfaces have same radius of curvature, with finely polished. Bi convex lenses have positive focal length, so they are used for 1:1 imaging and in ...
245291. Optical Fused Silica Glass Plano Concave Lens [Jan 27, 2023]
[Jan 27, 2023] Plano-concave lenses are thicker at the edge than in the center and flat on another surface. Plano concave lens (PCV) has negative focal length. So the lenses are used to bend parallel input rays so they can diverge ...
245292. Factory Customized Optical Glass Bk7 Convex Concave Lens [Jan 27, 2023]
[Jan 27, 2023] Meniscus lenses are designed to minimize spherical aberration. When used in combination with another lens, meniscus lenses will shorten the focal length and increase the NA of the system without introducing significant ...
245293. UV Fused Silica Jgs1 Plano Convex Lens [Jan 27, 2023]
[Jan 27, 2023] Plano convex lenses are designed to focus and collimate the light in optical system. The lenses are often used for laser, fiber, medical, sensor, communication and surveying instruments. Plano convex lenses are offered ...
245294. Cylindrical Lens for Laser Instrument [Jan 27, 2023]
[Jan 27, 2023] A cylindrical lens is a lens which focuses light into a line instead of a point, as a spherical lens would. The curved surface or surfaces of a cylindrical lens are sections of a cylinder. And focus the image passing ...
245295. Large Size Bk7 Plano Concave Lens [Jan 27, 2023]
[Jan 27, 2023] Plano concave lenses are flat on one side and have concave surface for another side. The lenses are designed for parallel light to be incident to the concave surface. So the plano concave lenses are used for ...
