INOUIRY
The plano convex cylindrical lens forms a linear image, which is used to control the size of only one direction of the beam. The material of this lens is BK7, so it is not suitable for ultraviolet wavelength. Compared with spherical lens, the manufacturing of plano convex cylindrical lens is more difficult. Materials (texture, bubble, impurity, uniformity) shall be selected reasonably, and factors affecting scattering (scratch, dent, gloss) shall be paid attention to, and high-quality grinding shall be carried out. It can be divided into uncoated and visible band coated antireflection multilayer lenses.
It is used in the experiment of condensing laser into thin line shape, or in fluid measurement.
Processing size range: 5-500mm
