For mobile, independent applications, LASER COMPONENTS offers the LT-PLM-IRB series alignment lasers with integrated battery pack. Beam angle error for the series is 0.05 mrad, which corresponds to a deviation of ± 0.05 mm at 20 m. Delivering a bright, visible red beam, the lasers exhibit a wavelength of 635 nm with an optical power of 1 mW. Additionally, the integrated battery has a capacity of 400 mAh for an operating duration of 10 hours. Battery pack and laser are included in one housing measuring 130-mm long and 35-mm in diameter.
