Digital U-type MM

IPS proprietary multi-mode U-type offers high output power with narrow spectral bandwidth with fiber coupling. The laser’s stabilized peak wavelength remains “locked” regardless of case temperature (15 to 45 ºC). . The laser is integrated with high performance laser drive and temperature control electronics in a compact package. In addition to integration into systems, IPS’ OEM U-Type module is designed to “drop in” to our UL/CE and IEC certified turnkey modules to offer wavelength flexibility at a lower cost.
