 This
4-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 should be ordered at time of purchase. In general, our Model 4HPS is recommended if both Plano and Spherical work are intended. For Plano work the vertical format is often 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 4VPS is dependent upon the length of the vertical support rails chosen by the customer at the time of purchase. The Model 4VPS 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 4VPS is equipped with EndoPhazeTM phase shifting under the control of Durango Universal Interferometry Software and installed in a high speed computer equipped and includes 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. This rugged instrument is equally at home in the QC lab or in the optical fabrication shop. With excellent repeatability and reproducibility, this precision instrument provides the metrology required for all of your optical shop requirements.
