Laser optical collimating lens focusing lens 400-700nm  EFL8mm

Collimating lens is an instrument that converts light from each point in the aperture column into a parallel column of collimating light.Lens type depends on aberration requirements,For low requirements, simple lenses, such as flat convex or double convex lenses, maybe used and a larger relative aperture is allowed.High requirements,Achromatic lens will be use, the relative aperture is also appropriately reduced.
