DAVIDSON OPTRONICS Model D-305 Plano Interferometer

PLANO INTERFEROMETER -- D-305

Laser Beam Warning The Plano Interferometer Model D-305 incorporates a built-in Polaroid Camera with a 3 position turret eyepiece consisting of an eyepiece for visual observation, Filar Micrometer Eyepiece for accurate measurement of fringe intervals and camera position for obtaining permanent film records. Extra attachments and accessories are no longer necessary.

The advanced design of this instrument provides the capability for assembly line and non-technical personnel to accurately measure surface flatness to 0.000 001 inch, with permanent records for future reference. One fringe = 0.000 012 4 inches or 0.000 316 mm.

Features:

No vibration table required in most cases
Built-in Filar Micrometer Eyepiece eliminates measuring errors
Swiftly measures flatness to 0.000 001 inch
Attached Polaroid Film Packet provides permanent records for future reference
Certification of accuracy traceable to National Institute of Standards and Technology

For more theory of operation, please refer to the Principles of Interferometry Application Note.
