The most common type of beam expander is derived from the Galilean telescope which usually has one negative input lens and one positive output lens. For low expansion ratios (1.3 - 20 times) the Galilean telescope is most often employed due to its si...

For challenging applications, our fully motorized high precision system Power Zoom can be used. These industry proven systems offer outstanding repeatability and reliability in divergence and magnification adjustment.

Our zoom beam expanders are highly corrected 4 element systems. The version with divergence adjustment is very user friendly, as the magnification setting and the divergence setting are independent from each other, i.e. the divergence remains unchang...

Our beam expanders with fixed expansion factor offer certain advantages compared to systems consisting of only two single lenses. For collimation, we use either an air spaced two lens system or an achromat in order to minimize chromatic and spherical...

Adjustable expansion ratio Adjustable divergence Galilean design EKSMA OPTICS offers compact Galilean type zoom beam expanders for Nd:YAG lasers fundamental and its harmonics wavelength: 1064 nm, 532 nm and 355 nm. Zoom beam expander provides ...
