Holmarc's Geometrical Optics Experiment Apparatus (Model No. HO-ED-O-02) is developed for general physics education in universities and colleges. The compact and fully integrated design makes Holmarc's Geometrical Optics Experiment Apparatus an ultimate tool to study the basics of optics.

It includes 1500mm long graduated optical bench with carriers. The optical components such as lenses, mirrors, etc. are fixed to the carriers using suitable mounts so that these can be fixed anywhere on the rail.
Students can easily adjust positions of optical devices using the sliding carriers. All the accessories are easy to be mounted and adjusted. The apparatus includes set of lenses, concave and convex mirrors, light sources like laser, LED etc. The use of diode laser as light source makes the ray path visible and helps students to assimilate the basics easily.

Experiment:

To measure the focal length of convex lens, concave lens, convex mirror and concave mirror.
   To verify inverse square law.
   To verify law of reflection.
   To verify law of refraction and to find the refractive index of water.
   To construct laser beam expander.
   To construct collimator.
   To construct simple and compound microscopes.
