Lasers & Opto-Electronics
Holmarc's Model no: HO-ED-LOL-01 is designed for performing innovative experiments and carrying out optics related projects. It covers all the major topics such as Michelson interferometer, diffraction, opto-electronics, optical fiber, laser, polarization etc. Experimental setups can be easily assembled on the optical breadboard. Students get hands on experience and knowledge of the experiment.
The laser optics lab consists of a honeycomb optical breadboard with rigid supports and various opto - mechanical and optical components. The components are fixed to the readboard by M6 socket head cap screws.
Total internal reflection is an optical phenomenon that happens when a ray of light strikes a medium boundary at an angle larger than the critical angle with respect to normal to the surface. If the refractive index is lower on the other side of the boundary and the incident angle is greater than the critical angle, no light can pass through and all of the light is reflected. Laser Optics Lab is designed to perform more than 30 experiments using diode laser. Instruction manual with complete information and diagrams is provided along with the apparatus.
