The L-700/L-701 are Class II diode lasers designed primarily for alignment of spindles to sub spindles or tailstocks. They has 4 axes of adjustment to align the laser beam to be co-linear and concentric to the center of its mounting stud or the axis of rotation of a spindle in which the unit is mounted.

The L-700 is typically used in applications up to 30 feet (9.1 M), although the laser can be used out to 100' (30.5 M). The L-701 has 3 times finer angular adjustments to allow it to be aligned to reference targets up to 100 feet (30.5 M) away. Built-in levels on the top and bottom provide easy indexing when inverting for error correction readings.

Other features include a shutter to protect the optics and an LED to indicate when the beam is on. Power is provided to the laser by a standard 9V battery for up to 8 hours of operation. The unit comes with a 0.5" (12.7 mm) mounting stud that simplifies fixturing and can be removed to adapt the unit to custom fixtures or other alignment applications. It can be used with the L-111 Laser stand for non-spindle applications.


  • Headstock spindle alignment to sub spindles or tailstocks
  • Transfer-line spindle alignment to master parts
  • Rotary dial machines
  • Boring bars
  • Turning applications (cylindrical, OD/ID grinders, lathes)
  • Twin-barrel extruders


  • Mounts in the spindle to project its axis of rotation, allowing even the largest transfer line machines to be aligned quickly and effortlessly.
  • Vertical and horizontal controls on the front for both angle and center for fine-adjustment of laser to spindle axis of rotation.
  • T-261A 4-Axis Target provide live measurement data in 4 axes simultaneously (vertical and horizontal angle and center).
  • Simple fixturing for mounting the laser and target.
  • Visible-light beam aids setup.
  • Runs for up to 8 hours on a standard, replaceable 9-volt battery.
  • Compact and rugged.
