What is it?

The DVD400 Interferometer System provides high-accuracy, noncontact measurements of transmitted-wavefront quality for small lenses in the 1.5 mm to 6 mm range. It uses a 405 nm laser diode light source in a Fizeau interferometer, includes MetroPro metrology software running on Microsoft Windows XP, and supports quantitative measurement and analysis with 1X, 2X, and 4X magnifications.
