L-111 Mounting Stand for L-700/L-705/L-706 with X-Y Angular & Center Adjustment

L-111 Mounting Stand for L-700/L-705/L-706 with X-Y Angular & Center Adjustment


The L-111 Laser Stand is used to hold the L-705, L-706 and L- 708 Lasers, typically for high-accuracy bore alignment applications where it is desirable or required to mount the laser outside the bores. It has coarse Pitch (vertical) and Yaw (horizontal) angular adjustments and is used to buck-in (make parallel to) the laser to two reference points. It works with the L-102 Beam Translator, which optically centers the laser in the first reference bore.

The L-102 Beam Translator is an optical beam-steering device used to translate the vertical and horizontal position of Hamar’s straight-line lasers without affecting the angle of the laser beam. It is typically used with the L-111 Laser Stand and features coarse and fine adjustments for translations as small as .0001 in. (0.0025 mm) and ± .100 in. (±4 mm) maximum beam displacement.
