Fizeau Interferometers
The interferometers can be built to a variety of specifications affording
standard accuracy of up to ¹/10 wavelength flatness over 80%
of the operating reference flat diameter. Offering economy with purpose
need
Essentially updated versions of systems introduced by HILGER many
years ago, our Interferometers are Laser Illuminated and fitted
with a wide angle viewing telescope.
They are practical and very stable workshop instruments.
Three aperture sizes are offered as standard, 10", 6"
and 4", the latter finding considerable merit in semi-conductor
wafer manufacture.
Micrometer tilting stages, Polaroid cameras, vacuum chucks and C.C.T.V.
cameras are offered as optional extras where appropriate

For the accurate measurement of Prism angles the OTI Goniometer incorporates the OTI Autocollimator with the OTI Precision Rotary Table.
