Laser interferometer
VMS 200 Pratt & Whitney

Our exclusive digital interferometer measures the dimension of the specimen by comparing the measurement probe position to the wavelength of a HeNe laser light source, effectively coupling the wavelength of light to the part being measured. Our patented laser path is in-line with the measurement axis to eliminate Abbe offset error.

The Laseruler has the advantage of having two instruments in one, a direct reading instrument and it can be used as a gage block comparator.
