DESCRIPTION
A beam expander is any optical system designed to increase the diameter of a laser beam.
In most cases, the term is taken to mean a telescope designed to take a small-diameter collimated beam input beam and produce a larger diameter collimated output beam, thus reducing the divergence of the beam.
The beam expander consists of a negative input lens and a positive objective. The expansion factor is the ratio of the focal length of the two lenses.
X3 Beam Expander
A beam expander is a set of lenses that increase the beam diameter and improve collimation.This makes the beam brighter at longer distances.
Our X3 beam expander makes it possible to reduce the diameter of your laser's beam at maximum range - increasing the effective range of your laser by up to 3.3 times.
Constructed with a stable stainless-steel housing, Our beam expander has an adjustable focus allowing you have fully control to the beam!
The beam expander works with these model: SW3, SW5, SW6, SW7, SW8, SW9 series laser pointer(Green, Blue, Red, Purple & Infrared).
