Manual Variable Magnification Beam Expanders
LINOS® Beam Expanders are designed to give laser system designers greater flexibility in laser material processing applications. By adjusting beam diameter and divergence, they help optimize focus size, focus position and beam propagation to meet specific process requirements. Changing the divergence of the incoming laser beam also allows the back focal length of F-Theta-Ronar or Focus-Ronar lenses to be adapted as needed. Continuous magnification from 1× to 8× is available. In addition, Excelitas offers manually adjustable beam expanders with fused-silica entrance lenses to support higher laser resistance.
Excelitas offers standard versions of manual variable beam expanders made of fused silica and/or optical glass. LINOS Beam Expanders are optimally employed in conjunction with LINOS F-Theta-Ronar lenses and offer:
- Continuous variation of magnification 2x...8x
- Choice between fused-silica or glass entrance lens
- Continuous variation of exit-beam divergence
- Wavelengths 355 nm, 532 nm, 633/780/830/980 nm or 1064 nm
- Precise scales allow reliable settings and high repeatability
- Max. exit-beam diameter 31 mm
- Max. length 165.5 mm
- Max. diameter 42.0 mm
- Mounting diameter 37.6-0.1 mm, reference on surface A
