The LDM127 laser module features a 19 by 34mm oblong housing which allows the user to
reference the laser to a mounting surface using either the front or bottom surface. Both of
these surfaces have a choice of four mounting holes which can be used for securing the laser
or for alignment and the optical axis is aligned to the housing. The flat surfaces allow superior
heat sinking of the laser, compared to conventional cylindrical laser modules.
Available in wavelengths of 520, 635, 650, 670, 780 & 850nm with power up to 5mW as standard.
It requires an operating voltage of 5Vdc (520nm requires 10Vdc) and features an isolated body.
As a further enhancement the LDM127 can be specified with a TTL modulation input with a
bandwidth up to 100KHz (red and IR models only).
A choice of two collimating lens are offered. The "G" model use a glass lens with an elliptical

output beam, the "P" model use a plastic lens which
produces a circular output beam with a lower beam
divergence. Both models have user adjustable
