DAVIDSON OPTRONICS Model D-321 Macroplano Interferometer

MACROPLAN INTERFEROMETER -- D-321

Laser Beam Warning The Macroplan Interferometer D-321 is an optical measuring instrument used testing the flatness of small reflective surfaces where a 2X magnification would be advantageous. It is designed for use in laboratory or on a production line. Suited for laser rods, micro-electronic components, memory core bits, gage blocks and optical flats. No physical contact is made between the master reference and the selected surface to cause wear or damage to either surface. Non-technical employees can perform measurements in millionths of an inch with the D-321 Macroplan Interferometer.

Features:

2X magnification over 1½" working aperture
Measures flatness to 0.000 001 inch on 0.060" diameter surfaces
Operation simplicity cuts set-up time
No physical contact between master reference and selected surface
Costly optical flats eliminated
Variable position stand
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.
