Fixed ratio beam expander is a device dedicated to increase the diameter of a laser beam.
Altechna’s beam expanders are assembled using one diverging and one converging lens. As there is no focal point inside of the beam expander, it can be used with high power laser sources. Special treatment of lenses and mechanics is performed for UV application to improve lifetime and LIDT of the expander. Standard magnifications are from 1.1x to 5x. Beam expanders for any wavelengths between 266 – 1064 nm are available upon request.
