245776. UV Fused Silica Glass Jgs1 Bi Concave Lens 
[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, ...
245777. Surveying Level 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 ...
245778. Calcium Fluoride (CaF2) 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 ...
245779. Single Concave Lens Negative Lens Diverging 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 ...
245780. Bi Convex Lens for CCTV Camera [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 ...
245781. Anti Reflective Coating Biconvex 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 ...
245782. Double Concave Lens with Optical Bk7 Glass [Jan 27, 2023]
[Jan 27, 2023] N-BK7 bi-concave lenses have equal radius of curvature on both surfaces. Bk7 bi-concave lenses are often used to expand light beams or to increase focal lengths in optical systems, and are normally used in combination ...
245783. UV Grade Fused Silica Condensor 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 convex ...
245784. Beam Expanding Optical Glass Bi Concave Lens [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, ...
245785. China Factory Plano Convex Spherical 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 convex ...
245786. Surveying Level Double Convex Lens with Optical Glass [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 ...
245787. Plano Concave Lens Optical Glass Negative 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 ...
245788. Ar Coated Cylindrical 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 ...
245789. Biconvex Lens Diameter 40mm Focal Length 60mm [Jan 27, 2023]
[Jan 27, 2023] Bi 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 of ...
245790. Double Concave Lens-Plano Concave Lens-Biconcave Lens [Jan 27, 2023]
[Jan 27, 2023] N-BK7 bi-concave lenses have equal radius of curvature on both surfaces. Bk7 bi-concave lenses are often used to expand light beams or to increase focal lengths in optical systems, and are normally used in combination ...
