Digital U-Type (Single-Mode)

IPS proprietary single mode "U-Type" offers 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, the 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.
