Ondax’s LMFC Series Fiber Coupled Single Frequency Laser Module couples an Ondax SureLock™ VHG-stabilized laser diode to a sin-gle-mode, polarization-maintaining fiber, delivering steady, single frequency performance in an ultra-compact footprint. Offering both computer and integrated user controls, the LMFC Series includes precision temperature and current controls to deliver better than 1m coherence length and 1% power stability with less than 1 minute warm-up. This tightly integrated package makes it the ideal choice for both OEM instrumentation and laboratory applications.
The LMFC Module is available in wavelengths from 405nm to 830nm.
