4D offers a wide range of diverger optics with outstanding optical performance. The list of available divergers includes F/1, F/1.5, F2, F/3, F/4, F/5, F/6, F/7, F8, F/10, F/11, F17, and F/21 focal ratios. The lenses are nominally parfocalized to make it easy to interchange lenses in a test setup. The optical performance of most of our divergers is specified to meet or exceed a Peak to Valley accuracy of 0.13 waves at 633 nm. All optical elements have high performance, narrow band coatings to effectively eliminate stray light. The interferogram above shows the typical performance of one of our lenses (measured on a PhaseCam™ of course!) A precision reference sphere is also available to allow the calibration of your system to 0.05 waves accuracy. Diverger lenses can be ordered individually or in boxed sets (shown below.) They are delivered in wooden storage boxes with complete QA certification. We also offer a number of different beam expander options (show below-right) for measuring nominally flat surfaces. Apertures diameters of 25 mm, 50 mm, 75 mm, and other custom diameters are available.
