Motorized OEM Attenuator LPA

The compact, motorized laser power attenuator series LPA is designed for laser power control and stabilization.

The LPA can be produced for use in the UV, visible and NIR spectral ranges, from 250 nm to 2000 nm. These devices have a unique mechanical, closed-loop optical and integrated electronics design ensuring high stability, repeatability and minimal device dimensions.

All optical elements of these laser power attenuators are made for high LIDT and provide stable and reliable performance even if used with high power lasers in industrial applications.

The secondary laser beam from the laser power attenuator unit is rejected through the output window to the external beam dump (optional) in order to avoid any thermal effects or stress in the housing of the LPA device.

 

Beam Delivery System BDS

The attenuator LPA can be combined with OEM Beam Expander Series MEX. Specifications of the BDS series are enclosed in the pdf.
