Product description

Sign the laser pointer through a grille and determine the wavelength.
Compare different interference patterns using laser pointers of different colours.

The laser pointer is also ideal for "writing with light" on the Phosphorescence Plate (art. no.: 41063).
The eye perceives violet light to be weaker than red and green light. This is why this laser pointer is less suitable as a pointer than the red and green laser pointers.

Dot diameter: 4 mm at 5 m.
Material: Strong casing made of metal.
Batteries: 2 x LR03 (supplied).
