Data Harvest

Product Description


This solid-state Laser module draws power from an EasySense logger to produce a red light of 645 to 665 nm wavelength.

It is designed to be used in optic investigations that require a coherent light source e.g. Youngs slits experiments or single ray optic investigations. There are two optical slides supplied, one is a set of single and double slits and the other a set of diffraction gratings. Both are suitable for wavelength of light investigations.
