What is a laser collimator

A collimator is an optical system used to focus or concentrate laser light into a single point or plane. A collimator consists of one or more lenses that focus laser light into a single point or plane, creating a focused and uniform spot.

Collimators are often used in lasers to control the shape and size of the laser beam, which is important for many applications such as laser machining, laser scanning, 3D printing, etc. Collimators can also be used to control the size and shape of the spot, which is important for precision material processing.

Collimators can also be used to control not only the shape and size of the laser beam but also its direction, which is important for applications such as microscopy and industrial applications.
