Variable Zoom Laser Beam Expanders

Standa’s diffraction limited Galilean type beam expanders offer variable magnification of 2x-12x or other ranges (see table below) with adjustable focus to correct laser beam divergence. All adjustments can be made quickly and easily by hand using our unique zoom and focus scale engraved directly onto the beam expander. No special tables or fine adjustment curves are required.
Standa’s experience in designing and manufacturing fine mechanics for many years reflects on 10BE03 zoom and focusing mechanisms. Frequent set-up changes without compromising optical and mechanical performance are common to 10BE03 series.

For those who don’t need frequent set-up changes we may offer a simplified version of 10BE03. Optical performance is the same as for 10BE03, but zoom and focusing mechanisms are designed for using with beams with nearly constant parameters (beam diameter and far-field divergence).

Mounting our beam expanders has become easier than ever. You can chose a variety of mounts from our 5KOM, 5TOM, 5TLM-1TH.

Should you require a custom solution to fit your application, please contact us for details. Our experienced personel will perform optical scheme calculations for your beam expander. Both – optics and mechanics – are manufactured by Standa.
