Optogama designs and manufactures compact Motorised laser power #attenuators and beam delivery systems used to increase or decrease laser beam diameter and adjust laser power from one device. Galilean type laser beam expanders integrated together with laser power attenuation module allows to control all the laser output patameters from one device!

BDS could be produced for use in the UV, visible, and NIR spectral ranges. These devices has a unique mechanical sliding-lens design, ensuring high pointing stability and minimal dimensions.

These variable magnification (zoom) beam expanders and reducers are designed for required wavelength and each type of our beam expanders has a divergence adjustability. Module laser beam attenuation unit can be integrated together for BDS series systems in one device, or it can be used as separate module..

All optical elements of these Beam delivery systems are made of fused silica with high LIDT coatings and provide stable and reliable performance even using them with high power lasers.

Secondary laser beam from laser power attenuator unit is rejected out trough output window to external beam dump (Optional) in order to avoid any thermal effects or stress in the housing of BDS device.
