2, 4, 6, and 8 inch Models
Graham Optical Systems offers a new series of vertical Phase Interferometer configured for Plano or spherical work. Note that for spherical work, an appropriate transmission sphere is required.
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 required adjustment utilizing the Two-Spot alignment feature. It is recommended at the time of purchase, that customer select the length of the vertical rails to accommodate the thickest test pieces to be measured . The sturdy tip/tilt table has been designed to support substantial mass. Its height is adjustable in order to decrease the air gap between the reference surface and the test piece to minimize the effect of air currents.
Standard equipment provides remote control of focus, zoom and intensity. In the VPS series, Durango Universal Interferometry Software interacts with Graham's EndoPhazeTM system to control Phase-Shifting. Durango Software is installed and configured in a 2.2 GHz All-in-One Computer.
Durango provides a wide selection of data outputs and colorful graphics and offers a live interferogram on the computer monitor so no separate video monitor is required. The operator can select the features that he wishes to display on the screen from among an assortment of graphics and data reports. Durango permits the QC manager to set the criteria for the pass/fail feature, thus permitting the routine measurement of test pieces by less skilled personnel.
These rugged instruments
are 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 plano measurements.
