Laser diode module COHERENT

Focusable Diode Laser Modules

These 635nm/670nm/830nm diode laser modules have adjustable focus with elliptical, circular or line generator beams.

Focusable diode laser modules combine the technology of high-quality diode lasers with superior optics, sophisticated electronics and rugged alignment packaging. These modules can also be used in many applications to reduce the requirements for external optics. The result is an overall system that is smaller, simpler and less costly.

The adjustable focus is a great benefit for many applications. For machine vision, particle measurements and inspection-and their inherent need for direct measurements-the beam can be focused at a distance for the smallest spot size to optimize the system resolution. For fiber launch the adjustable beam can also optimize the focus spot position to achieve the ideal coupling efficiency. For instrumentation applications with multiple laser sources, the adjustable focus can match the red laser beam properties to another laser to simplify integration requirements.

The front knob allows for easy adjustment. During adjustment the optics do not rotate and focusing action is even and uniform while beam alignment is maintained.1 A locking ring is used to secure the focus in any position. Use the VLM2 mount [part no. 0221-437- 00] for convenient heat sinking and mounting with adjustable alignment. For lasers without a connector, order plug no. 1057734.
