Fixed beam expander

The two lenses of the fixed beam expander are fixed and cannot be adjusted by the customer after leaving the factory. During factory production, we can fine tune the distance between the two lenses to obtain the best parallel beam. Fixed beam expanders are divided into two types: cylindrical connections and threaded connections. The threaded connector can be directly connected to our beam expander frame BEM22x0.75, making it very convenient to use.

(2) Adjustable beam expander

Adjustable beam expander is designed specifically for laser beam expansion with large divergence angles. By adjusting the distance between the expansion lenses, the influence of divergence angle can be eliminated within a certain range, thereby obtaining a laser beam with good collimation after expansion. When the incident laser has a large divergence angle, gradually increasing the distance between the lenses can obtain a collimated laser beam at a certain position.
