Designed for safety the laser is now very low-power (1mW) and is protected by a key switch to prevent its unsupervised use. The power output places the laser in Class 2 as recommended for use in schools and colleges. No damage is likely should a stray reflection of the beam enter the eye at such low power.
The wavelength of the light is 635nm which compares favourably with the helium-neon wavelength of 632.8nm.
Additional features include:
Tapped (M5) exit hole for possible mounting of optical components, fibres etc. Closest to the point of emergence of the beam
Laser support arm (from the laser accessories kit) connects to a tapped mounting point and allows the laser to be supported using an ordinary clamp stand and boss
Metal case fitted with 1.8m of mains cable, illuminated ON/OFF switch, locking key switch with 2 keys
250mA fuse
This device is compliant to EN61010-2010 with certificates available on request
Wavelength: 635nm. Beam diameter: 6mm at 5m. Divergence: 3mrad
