Dual Color Laser with Modulation YGroup_airpucks Mass values are embossed directly

Mass values are embossed directly into the metal so they won’t rub off with use

this device is perfect for weather enthusiasts of all ages

and automatically powers off to conserve battery life

Better insulation: 12 mm thick walls reduce heat loss for more accurate calorimetry results

Dual Color Laser with Modulation YGroup_airpucks Mass values are embossed directlyDual color laser for optics and modern physics labs More than just a laser pointer, Arbor Scientifics Dual Color Laser is a versatile optics and modern physics tool designed for real investigations. This modulated semiconductor laser contains two independently controlled laser diodesa 650 nm red and a 532 nm greenallowing students to directly compare how wavelength affects diffraction, interference, and beam behavior. Both lasers can be used
