Cylindrical Lenses
Cylindrical lenses aren’t spherical lenses, can effectively reduce the spherical aberration and chromatic aberration. they are widely used in barcode scanning, projection optics systems,laser measurement system and holography.
Main wavelength have 780nm,980nm,1030nm,1064nm,1550nm etc.
Cylindrical lensed are available in either plano-convex or plano-concave, configurations as below.
