Diode Laser Source


Product Description

Model LD-15s is an economical, smaller, and more efficient alternative to HeNe Lasers.


Model LD-15s emits a low-power beam which makes it perfectly safe for use in the lab, or for independent student use.

As an added safety feature, a key-operated 2-position power switch allows the teacher to lock down the output power from 1.0 to 0.5 mW making the unit even safer for use by students.


The diode generates a narrower and more directional Laser beam than a conventional HeNe Lasers. This makes it practical for experiments that require extended beam trajectories. Precision is guaranteed by a built-in 3-lens optical focusing system.

Model LD-15s is ideal for the demonstration of rectilinear light propagation and for the study of diffraction and interference.
