High Power He-Ne lasers are ideal for applications requiring high speed scanning, superior signal to
noise ratio, and high visibility beams over long distances.
The single mode outputs of all lasers offer high signal/noise ratios and consistent Gaussian beams,
which are highly efficient for coupling into delivery systems. Polarization versions are for phase and
orientation sensitive applications.
All lasers are tested to meet demanding lifetime, performance, and quality standards along with
CDRH and IEC laser safety requirements. Laser housings are rugged aluminum, with a mechanical
shutter at the output end. Power supplies have key locks, on/off indicator, 3.5 to 7 second time delay,
and remote interlocks. All lasers are available in 110V or 220V (w/Europlug) formats. Required power
supplies sold separetly. All lasers comply with 21-CFR-1040 and IEC 825-1:1993.
Recommended for use with our laser line generators for alignment and pointing projects. Bezel
accessory (#61-344) is required for use with any of our laser accessories.
