4Lasers designs and manufactures compact motorised laser beam delivery systems with integrated laser power attenuators used to increase or decrease laser beam diameter and adjust laser power in one device!
BDS could be produced for use in the UV, visible, and NIR spectral ranges. These devices have a unique optomechanical closed loop sliding-lens design with all integrated electronics in the device ensuring high pointing stability and minimal dimensions.
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.
