Motorized OEM Beam Expanders MEX

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.

Description

  • 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.

Options 

Manual 4 axis translation stage for MEX fine adjustment

In order to facilitate adjustment, we offer a manual translation stage especially designed for the beam expander series MEX. For technical details, please download pdf in documents tab.

Features

  • Sapphire contact pads
  • Platform’s locking mechanism
  • Industrial design
  • 4 axis fine adjustment
  • Maximum load up to 1.5 kg
  • Can be fixed on both Metric and Imperial optical breadboards and tables

Applications

  • Motorized beam expander MEX fine adjustment
  • Optical element adjustment

MSTAGE is an industrial 4-axis manual translation stage with locking mechanism. It has sapphire contact pads for prolonged accurate adjustment.

There are four M6x0.25 microscrews for adjusting platform’s pitch, yaw, Y and Z axis. Two microscrews control platform’s pitch and Z axis, while another two control yaw and Y axis. All of them can be adjusted with 2 mm HEX screwdriver.

What’s in the box?

  • Manual translation stage
  • 3 x M4x0.7 10mm long screws for MEX mounting
