(Note: Mitutoyo objectives have a 26mm x 36TPI)

These diode lasers can used in place of Argon and Krypton lasers. Output beam is circular with Gaussian profile and have diffraction limited performance. They are smaller in size with very low power requirements compared to gas lasers.

Our turnkey system simplifies operation for the researcher. No additional heat sinks, control box or power supplies are required. The system just plugs in and turns on. Output power is adjustable with option for modulation. Users can easily migrate to the OEM version when they are ready for system integration. OEM versions have full access to all laser parameters and many monitoring functions. Includes external voltage controls.

We offer many compatible optical assemblies for focusing, expanding or shaping the beam. We also have ring and plate adapters to mount the laser onto common optical mounts and tables.
