The motorized beam expander series MEX is used to the laser beam diameter (up to factor 8) and to adjust divergence. The wavelength-specific devices stand out by their high pointing stability (< 0.1 mrad) and the compact and long-lasting design. Control software is included. Alternatively, direct programming for OEM integration is also possible.
Features
- High beam pointing stability (up to < 0.1 mrad)
- Fused silica optical elements
- Integrated controllers
- No homing after switch on/off
- Diffraction limited performance for all magnifications
Applications
- Precise laser micromachining
- Life sciences
- Research
Compact Motorized OEM Beam Expanders MEX
The motorized laser beam expanders, collimators & beam reducers MEX series is used to increase or decrease the laser beam diameter and to adjust divergence. Standard or custom made beam expanders and reducers have a unique mechanical closed-loop sliding-lens design, ensuring high pointing stability at minimal dimensions.
These variable magnification (zoom) beam expanders and reducers are designed for the required wavelength and each type of our beam expanders has motorized divergence adjustability.
High Power Motorized OEM Beam Expanders MEX-HP
The high power models MEX-HP are designed for use with up to 200 W output power, 500 fs pulse duration and 1 MHz repetition rate.
Beam Delivery System BDS
The beam expanders MEX can be combined with the Motorized OEM Attenuators LPA. Specifications of the BDS series are enclosed in the pdf.
