5LAOM-Large Aperture Optical Mount

360 coarse rotation and 4° fine rotation. 150 kg load! High thermal and vibration stability. Near zero Backlash

5LAOM Large Aperture Optical Mount has been designed for positioning of large optical elements up to 600mm. Commonly LAOM optical mount is extremely efficient solution in applications such as: high power laser systems and astronomy.

LAOM series optical mounts have complete 360 degree rotation in azimuth and elevation axes if transmission of both coordinates is decoupled. Special spring preloaded internal mechanisms result near zero backlash motion. Fine adjustment in ±4° range results high quality motion with sensitivity less than 1arcsec.

Age hardened aluminum alloy guarantees softness of assembly, high thermal stability and high vibration stability.
