    Digital U-Type (Multi-Mode)

    DATASHEET

    The OEM Digital U-Type Module integrates our multi-mode fiber-coupled butterfly package with laser driver and TEC control electronics in a compact package. A USB connection and LabView customer GUI allow the user to control the device remotely.

    The multi-mode spectrum stabilized laser offers a narrow spectral bandwidth and super wavelength stability over time, temperature, and vibration. The laser's stabilized peak wavelength remains "locked" within a wide case temperature range. Devices can be tailored to suit specific needs, providing an extremely high signal-to-noise ratio, which is ideal for Raman spectroscopy.
