Pratt & Whitney Measurement Systems' has designed and developed dedicated fixturing for the measurement of films, meshes, and disk substrates for its Labmaster Standard Model LMS-200 series. This high accuracy and automated vertical measuring instrument can measure length and thickness with a push of a button. Our exclusive digital interferometer measures the dimension of the specimen by comparing the measurement probe position to the wavelength of a He-Ne 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.
With these fixtures, the Labmaster Standard is the instrument of choice for thickness measurement of thin, soft materials such as poly films, meshes, magnetic tape or disk substrates. Additional measuring applications include: coating thickness standards, textiles, and metal foils.
Pratt & Whitney, founded in 1860, is a global supplier of ultra-precision Metrology instruments, inspection gaging systems, and length measuring machines. Pratt & Whitney instruments incorporate the latest in laser and sensor technology allowing for fast and accurate measurements.
