ZFA-G-1120 Infrared Diode Laser
The ZFA-G-1120 is a high-power infrared diode laser module operating at 1120 nm, developed for precision measurement, optical communication, spectrum analysis, and advanced photonics applications. Featuring an ultra-compact design, long operational lifetime, and cost-effective construction, this CW infrared laser module is ideal for laboratory systems and OEM integration. The laser supports TTL and analog modulation from 1 Hz to 30 kHz, enabling precise dynamic intensity control for spectroscopy, communication platforms, and experimental photonics setups. Combined with universal 100–240 VAC power compatibility (QDI-J-ARF / QDI-J-GFS), fast warm-up time (<5 minutes), and an expected lifetime of 10,000 hours, the ZFA-G-1120 offers robust and stable infrared laser performance.
