(Available on Special Order Only)
8-inch aperture vertical Phase Interferometer, as shown, is configured
for Plano work only. There is no requirement to purchase a separate
transmission flat, -- the 1/20 wave reference surface is included and forms
an integral part of the collimator.
Note that if spherical work is planned, an optional Tip/Tilt plate with bayonet mount is required to attach external Transmission Flats or Transmission Spheres and should be ordered at time of purchase. In general, our Model 8HPS is recommended if both Plano and Spherical work are intended.
For Plano work the vertical format is usually preferred, since there is no need to mount the test piece in a fixture. The operator merely places it on the integral tip/tilt table and makes the appropriate adjustment. The overall height of the 8VPS is determined by the length of the vertical rails to be selected by the customer at the time of purchase, The Model 8VPS incorporates a sturdy tip/tilt table which has been designed to support substantial mass. Its height is adjustable in order to suit the requirements of the operator.
A Two Spot alignment feature is accessible through the remote control which also controls Focus, Zoom and Intensity. The 8VPS is equipped with EndoPhazeTM phase shifting under the control of Durango Universal Interferometry Software and installed in a 3GHz computer with a 22-inch TFT flat screen monitor. Durango provides a wide selection of data outputs and colorful graphics and offers a live interferogram on the computer monitor. No separate video monitor is required.
