The LDM145 integrated assembly consisting of a laser diode, collimating optics and drive electronics within a single compact

housing.  Produces a bright red dot at 670 nm at 3mW.  It is supplied complete with leads for connection to a DC power supply

from 3 to 5.25 V.  Though pre-set to produce a parallel beam, the focal length can readily be adjusted to focus the beam to a spot.

Sturdy, small and self-contained, the LDM145 is a precision device designed for a wide range of applications.

Module is new old stock.
