Semiconductor Laser, Free-Space Output LDF638-20
JCOPTIX separate-head semiconductor lasers include lasers/adjustable drivers, with thirteen wavelengths over 405-940 nm. High-performance LDs provide stable wavelengths and continuously adjustable 0-15/0-20 mW output. Advanced microprocessor control with precise ATC temperature and ACC constant-current circuits resists interference and stabilizes output. Drivers display current/power and use knobs for power. SMA DIG/ANA ports support modulation. DIG: floating or TTL-high enables emission; shorting turns it off. ANA: floating or above 2.5 V gives maximum power; 0-2.5 V varies power linearly. Good collimation, uniform intensity, near-circular spots, long life, and easy operation suit long-term optical testing, precision alignment, biological analysis, and biomedical imaging. Output faces have standard 30 mm cage 4-40# holes for ultracompact paths. 36 mm beam height matches MCO-B2/MCO-B4 supports for stable output paths. Contact support for customization. Semiconductor lasers. Models: LDF405-20, LDF450-20, LDF488-20, LDF520-20, LDF638-20, LDF660-20, LDF685-20, LDF690-15, LDF785-20, LDF830-20, LDF850-20, LDF905-20, LDF940-20. Thirteen wavelengths over 405-940 nm. Adjustable output: 0-15/0-20 mW. Compatible with 30 mm systems. JCOPTIX outputs collimated beams at 405 nm, 450 nm, 488 nm, 520 nm, 638 nm, 660 nm, 685 nm, 690 nm, 785 nm, 830 nm, 850 nm, 905 nm, or 940 nm. Standard 30 mm 4-40# holes directly connect rods. Laser/driver bottoms have M6 holes for tables. All powers adjust over 0-15/0-20 mW.
