MACROPLAN INTERFEROMETER -- D-311

The Macroplan Interferometer D-311 is an optical instrument for measuring flatness of small reflective surfaces where 2X magnification is advantageous.  Non-technical personnel can make accurate measurements on reflective surfaces as small) as 0.060" diameter.

With this instrument there is no physical contact between the master reference and the surface to be measured thus eliminating the, use of costly optical flats that must be replaced when worn.

• Features:
  • No vibration table required in most cases
  • 2X magnification over 1½" working aperture
  • Measures flatness to 0.000 001" on 0.060" diameter surfaces
  • Costly optical flats eliminated
  • Operation simplicity cut set-up time
  • No physical contact between master reference and selected surface
  • 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.

Detailed Specifications:

• Optional Accessories:
  • P/N 104-0150-311 Fringe Analysis System eliminates any human error in evaluation of your parts
  • P/N 105-2761-311 Video Camera & Monitor with integral camera power supply.  With this option readings become very easy even for unskilled personnel.  Repeat readings are more accurate and faster.  The camera eliminates any errors from parallax and greatly reduces eye fatigue.  This option is easily added to existing Model D-271's.
  • P/N 105-2703 1" Retro-Reflecting Corner Cube
  • Model D-190 Fringe Splitter
  • P/N 625-0011 Contrast Coated Divider Plate for viewing mirrors
  • Model D-311-103L with Swing-away Polaroid Camera
