Point Diffraction Interferometer (PDI) plates manufactured in Germany - 2nd generation - $100
With these plates it's very easy to build a point diffraction interferometer, for example for testing a telescope mirror. You only need a cheap red laser diode (without collimating lens), the PDI plate, a 3-axis stage, and a camera.
