BE SERIES: HIGH POWER LASER BEAM EXPANDERS
BE Series is a family of High Power Laser Beam Expanders featuring state-of-the-art optical performances.
Maximum lambda/8 wavefront distortion is guaranteed over a very large entrance pupil while the Fused Silica input lens ensures safe operation with the most powerful laser sources.
The focusing stability is ensured by a pre-load spring, while the non-rotating lens movement grants a pointing stability of less than 1 mrad.
BE Series are compact and robust and mechanically compatible with common standard threaded interfaces.
Cost-effectiveness makes these optics the solution of choice for any industrial laser system.
KEY ADVANTAGES:
- Wavefront Distortion less than lambda/8, for tiny spot size achievement
- Fused Silica Input Lens, for Laser Damage Threshold (LTD) up to 10J/cmˆ2 (10 ns)
- Pre-load spring and Blocking Knob, for high focusing stability
- Non rotating lens movement, for pointing stability within 1 mrad
- Large Entrance Pupil, also for high beam magnification applications
- Compact and Robust Mechanical Design, compatible with Standard Interfaces

Notes
| (1) | Listed length value is the nominal one (incoming perfeclty collimated beam). +/-2 mm course of the entrance optical element will make this length shorter or longer in order to compensate the input beam divergence. |
