Laser 0,2/1,0 mW, linearly polarized modulatable, magnetic

Class 2 educational laser for use as a high-intensity light source,
especially in experiments on interference, diffraction and holography.
Laser diode, with collimator optics, mounted in a "compact" magnetic module.
Wavelength: 635 nm; optical power output: 0.2 mW;
continuous maximum power output of 1.0 mW,
generated only while pressing the push button
(or using remote control switch DE722-2W);
beam divergence: < 0.5 mrad;
polarisation: linear; modulation input by means of phone jack;
operated using a built-in key switch; LED indicates operating mode;
four strong neodymium magnets are built into the back plate
for mounting the device on a metal panel;
holder for "compact" components DS617-1H is required for mounting it on a support stand;
operating voltage: 9 V battery (supplied)
or 6 - 12 V DC, supplied through the 5.5 mm hollow jack
(e.g. by mains transformer P3130-1P);
case dimensions: 84 x 84 x 39 mm
