    4Lasers designs and manufactures compact LPA series motorized laser power attenuators for laser power control and stabilization.

    LPA could 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 using them with high power lasers in industrial applications.

    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 LPA device.
