5 beams, each max. 1 mW,
Laser safety class II
Wavelength:
635 nm
Separation of laser beams: 18 mm
Plug-in power supply: Primary 100 – 240 VAC,
Secondary 3 V DC, 300 mA
Battery compartment: for 2x 1.5 V AA-batteries
(batteries not included)
Dimensions:
approx. 110x60x20 mm³

Equipment Set “Optics with Laser Ray Box”
Set of optical components for use in combination with a laser ray box
(9982-1003052 resp. 9982-1003051) and related board (9982-1003056). This
equipment set is ideal for conducting a wide variety of experiments on ray
optics. Equipped with magnetic foil, the components can be easily attached
to the board and aligned. Six work templates with pre-defined positions facilitate
experiment setup. The beam paths can be observed from a relatively
long way away without any need for darkening the room.
Basic length:
100 mm each (in most cases)
Thickness:
15 mm each.
