    Digital U-Type (Single-Mode)

    Datasheet

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

    The single-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.

    For custom orders, wavelengths can be accurately specified and repeatedly manufactured withn +/-0.1 nm upon request.
