Fringe Analysis System featuring DURANGO SOFTWARE

contour_new.jpg (24066 bytes)

This is a powerful tool for testing in Application and Research and Development Laboratories and for Optics Fabricator Shops. Its simple and precise operation provides for fast fringe analysis. Permits quality control of most demanding optical components. Phase shift analysis can be routinely performed.

The contour map and phase height profile shown depict typical phase shift data obtained with a LUPI operating with a Fringe analysis system from DURANGO SOFTWARE

Calibration Sphere with Mount
(CSP™)

For calibrating the laser unequal pathlength interferometer:

·      2.5" (75 mm) Diameter, 2.5" (64 mm) Radius of Curvature,
     l / 20 P-V (l = 0.6328 microns) Surface Accuracy
·      Cell-Type Mount, Adjustable Tip and Tilt

*Space Optics Research Labs does not recommend the classic "View with an eyepiece"approach. Possible eye damage may occur when using an eyepiece to observe interferograms. Observe proper laser safety practices. Eyepieces are supplied for image projection not visual use.

Accessory Kit (AK-I™)

Permits measurement of cone angles from f/2 to f/20
·      Microscope objectives (3), including interferograms
·      Matching imaging lenses (5)
·      Objective extension tubes, 4/10" (10 mm) to 3" (75 mm)
      long   (4)
·      Eyepieces

Additional SORL components to create measuring systems.
·      Flat Mirrors (Test Flats)
·      Spherical Mirror (Hindle Spheres)
·      Mirror Mounts
