101341. Surveying Instrument Double Concave Lens with Optical Glass 
[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 ...
101342. Manufacturer Plano Convex Lens Collimating Lens Optical Glass [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 ...
101343. Spherical Meniscus Lens with Optical Glass [Jan 27, 2023]
[Jan 27, 2023] Meniscus lenses have one concave and one convex surface. For this lens type, the two curvatures are chosen to minimize the spherical aberration at one laser wavelength, hence meniscus lenses are used to control a laser ...
101344. Meniscus Cylindrical Lens with Fused Silica Glass [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 ...
101345. Wholesale Optical 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 ...
101346. Focusing Glass Lens Plano Convex Lens [Jan 27, 2023]
[Jan 27, 2023] Plano convex lenses have one plano surface and one convex surface, they have a positive focal length. Plano convex lenses are widely used for focusing and collecting light in optical instrument. We produce plano ...
101347. Factory Custom Made Double Convex Lens [Jan 27, 2023]
[Jan 27, 2023] Double Convex lens has a positive focal length, and with two outward surfaces. The two surfaces are with same radius of curvature, thereby minimizing spherical aberration. Some biconvex lenses are with different radius ...
101348. Fused Silica Glass Optical Flat for Camera [Jan 27, 2023]
[Jan 27, 2023] Optical window or flat is a polished piece of material that is transparent at some portion of the electromagnetic spectrum, which allows the desired portion of the spectrum to pass into an optical instrument unaltered. ...
101349. Biconcave Lens for Laser Beam Expander [Jan 27, 2023]
[Jan 27, 2023] Bi concave lenses comprise of two inward equally curved surfaces. They are ideal for beam expansion, light projection and expanding the focal length of an optical system. Bi concave lenses have a negative focal length, ...
101350. Manufacturer Double Convex Glass 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 ...
101351. Manufacturer Plano Concave Lens Double Concave Lens Optical Glass [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 ...
101352. Finely Polished Meniscus Lens for Endoscope [Jan 27, 2023]
[Jan 27, 2023] Meniscus lenses have one concave and one convex surface. For this lens type, the two curvatures are chosen to minimize the spherical aberration at one laser wavelength, hence meniscus lenses are used to control a laser ...
101353. Cylinder Lens with Optical Glass [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 ...
101354. Bk7 Glass Negative Lens Diverging 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 ...
101355. Sapphire Windows for Optical Instrument [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 ...
