Pinpoint Laser Systems' right-angle beam bender called the 90-Line. It takes the reference laser beam from the Microgage 2000 and turns it precisely 90 degrees. The 90-Line can be used to square machinery and equipment, set and adjust parallel tracks and rails, align web rollers, idlers and reels, check gantry travel and position, monitor and adjust machine tools, and assist in geometric alignment.
The beam bender is built with a housing for holding precision optical elements that redirect the laser beam. The exiting laser is square to the incoming beam within 0.0006 degrees, or equivalent to 0.001" over a distance of 8 ft. The housing has several adjustments, allowing the square exiting beam to rotate through a full plane. The beam can be adjusted with a precision rotary mount and a two-axis stage mount makes positioning the 90-Line easy.
