CylindricalHelium NeonLaser Systems
$ Red, green, yellow, orange, or near infrared output
$ Complete systems, including power supply
$ CDRH, IEC, and CE (230 Vac only) compliant
Melles Griot manufactures a wide variety of cylindrical HeNelaser systems, only the most popular of which are represented here.All laser heads are mounted in rugged aluminum housings andcome with a matched power supply. All systems meet CDRH andIEC requirements for laser equipment, and 230-volt versions areCE compliant. Lasers are available in randomly polarized or linearlypolarized (>500:1 extinction ratio) versions. For custom OEMdesigns and alternative wavelengths, contact your nearestMelles Griot sales office.

The Melles Griot family of high-power helium neon lasers exhibitthe long life, excellent stability, and field-proven performances thathave made Melles Griot the undisputed worldwide leader in heliumneon laser technology.
The 25 LHR/P 925, 828, and 928 lasers have guaranteed per-formances of 17, 25, and 35 mW, respectively, making them idealfor Raman spectroscopy, holography, fast scanning, and test andmeasurement applications. Most are available either in randomlyor linearly polarized (with >500:1 extinction ratio) configurations,and they can be mounted in a variety of orientations without sac-rificing power or performance. Systems are convection cooled andoperate from standard 100 Vac, 115 Vac, or 230 Vac outlets.
