About This Product
Turning the slow-motion drum moves a mirror and shifts the interference pattern, which is watched through the telescope while the bed scale, drum and disc record how far the mirror has travelled. The mirrors are coated on the front surface, with the second face optically polished.
Frequently Asked Questions
What scales does the interferometer have?
Three: a 0–150 mm linear scale graduated in mm on the bed, a graduated slow-motion drum of 0–100 divisions on the right-hand side, and a 0–100 division graduated disc at the head, read through a glass window, with 0.01 mm per division.
What size mirrors fit the holders?
The holders, fitted with mirror mounts, accept mirrors of 25.4 mm diameter and 12.5 mm thickness. The front-surface coated mirrors listed are 25 mm in diameter and 10 mm thick, with 90% reflectivity.
How are the fringes observed?
Through a telescope whose objective is an achromatic doublet of 25 mm diameter and 125 mm focal length, giving 10x magnification.
