Holmarc's Model No: HO-ED-INT-06C is a compact Michelson Interferometer. The beam splitter is designed to reflect 50% of the incident light and transmit the other 50%. The incident beam therefore is split into two beams; one beam is reflected towards mirror M1, the other is transmitted towards mirror M2. Half the light is transmitted through the beam splitter to M1 and the other half is reflected by beam splitter to M2. The reflected beams from M1 and M2 superimpose at the beam splitter and interference pattern can be observed on the screen.
The light passes through a greater length of glass as the plate is rotated. The change in the path length of the light beam as the glass plate is rotated and relates the change in path length with the laser beam through air.
The refractive index of glass slide,
N = (2t - Nλ) (1 - cos θ) / 2t (1 - cos θ) - Nλ
Where t is the thickness of the glass slide, N is the number of fringes counted, λ is the wave length of light used and θ is the angle turned for N fringes.
The distance between the mirrors and beamsplitter is fixed
The components are mounted on a rigid platform
The instrument uses laser diode as light source
Precision kinematic mounts for optical components
The optics used in this device are of research quality
Ours is an organisation dedicated for the design, development and manufacture of optics, opto-mechanics, educational products and positioning devices.
We have in-house infrastructure capabilities for all the processes involved in the manufacture of our products. This helps us to have total control of quality in our products and services.
Our core competency is in prototype development and low volume production of opto-mechanical devices and systems where skilled labour is the major input. Our location in INDIA enables us to be the most cost effective in this field of activity compared to any other company in the world.
The products described in this website constitute only the standard items we manufacture for research and industrial market. One of our major activity is in OEM market where we develop and supply low volume opto-mechanical devices & positioning as per custom design. We also undertake contract manufacturing of opto-mechanical products in standard and custom specifications.
We try improving the quality of our products for every consignment we dispatch. Our customers can expect to receive better products each time a purchase order is placed with us.
Our strength is our satisfied customers worldwide. We request your continued support in our endeavor to serve you better.
