Laser focus lens collimating cons

✨ Collimating lenses are curved optical lenses that make par- allel the light rays that enter your spectrometer setup. These lenses allow users to control the field of view, collection effi- ciency and spatial resolution of their setups, and to configure illumination and collection angles for sampling.

✨ In order to meet this requirement of modern analytical instruments, laser beams have to be collimated. This can be understood as putting a lens or a set of lenses in front of the laser cavity – does not matter be it a semiconductor laser cavity or a short DPSS resonator.

✨ The collimating lens is a common convex lens, where the diverging light enters, and the parallel light emits, and this convex lens acts as a straight line. The rectangular shape of these collimators does a better job at reducing patient radiation exposure than round collimation systems, so if your practice is still using round collimators, be sure to invest in a rectangular collimator.
