LEOK-8 Interference, Diffraction & Polarization Kit - Basic Model

LEOK-8 Interference, Diffraction & Polarization Kit - Basic Model


  • 8 fundamental experiments

  • Detailed instruction manual

  • Easy alignment

  • Affordable price


The LEOK-8 Optics Experiment Kit is developed for general optics education at affordable cost. It can be used to demonstrate eight experiments, covering interference, diffraction, and polarization laws of light. With a 12 V/50 W halogen-tungsten lamp as the light source, bright experimental phenomena can be demonstrated.


A list of eight experiments can be demonstrated as follows:


1. Double-slit interference

2. Bi-mirror interference

3. Newton's ring interference

4. Single-slit diffraction

5. Multi-slit diffraction

6. Grating diffraction

7. Polarization by reflection

8. Polarization by polarizer
