Biconvex lens
Biconvex lens Double convex lenses (Double Convex Lenses) are composed of two convex surfaces with equal radii, which can focus light into a point with a positive focal length. Due to the symmetrical shape on both sides, it is a more suitable single element for 1:1 imaging applications. It is oft...Read more -
K9 High Precision Wedge Window
K9 High Precision Wedge Window The two planes of K9 High Precision Wedge Windows have an included angle of 30 arc minutes. Two non-parallel planes can avoid the interference effect (Etalon effect) caused by the reflected light on the front and rear surfaces of the high-parallel window, and also a...Read more -
Plano-convex Lens
Plano-convex Lens Plano Convex (PCX) Lenses focus parallel light rays into a point, which is the focal point of the lens. It is characterized by a positive focal length, one side is flat and the other is convex. When in use, the convex surface is usually facing the incident light, because the inc...Read more -
