Pratt & Whitney Laseruler®

Your solution for vertical measuring is the Laseruler® which is laser-interferometer-based for very high accuracy.

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.

The Laseruler® measures:

Gage blocks
Balls/spheres
Ball bearings
Plug & pin gages
Thread wires
Film thickness
