LASERS AND DIODES
7 June 2012
Coherent has added two new wavelengths, 514nm and 552nm, to its Obis family of plug-and-play smart laser modules.
The Obis 514 LS and Obis 552 LS are now available with output powers of 20mW and offer an optimum combination of beam quality (diffraction limited TEM00 beam, divergence <1.2mrad, pointing stability <30µrad/±3°C) and power stability (<2 per cent over 8 hours ±3°C) and low noise (rms ≤0.25 per cent at 20Hz to 20MHz).
Together with its smart integrated controller, these lasers enable true plug-and-play operation, which is a unique Obis advantage for end users and OEMs alike. In particular the Obis laser facilitates an easier and simpler build of a new application or instrument with the ability to expand wavelengths and power easily. Obis lasers also simplify field exchange and upgrades with the common beam parameters and form factor.
All 14 lasers in the Obis series have a compact footprint 70 x 40 x 38mm (2.75 x 1.57 x 1.5 inches). Standard features include flexible operation via USB, RS 232 and serial interface ports to monitor and control all laser functions.
