Collimator Lens, and two Fourier Lenses, which are of achromatic-doublet design, selectively tested for performance at 0.6328 micron, helium-neon, with even higher resolution at 0.4880 micron, argon. System Operation: Pinhole Spatial Filter takes collimated laser beam and provides diverging output cone via precision X, Y, & Z micrometers, which align 40X objective lens precisely with 10 micron pinhole. The system contains 1 Collimator and 2 Fourier lenses: 7.6cm diameter, f/5 32 lines/mm resolution and lambda/8 wavefront accuracy over central 3.8cm aperture lenses assembled in cells tapped for easy mounting Pinhole spatial filter with 40X objective lens and 10 micron removable, magnetically-held pinhole will accept standard microscope objective lenses micrometer drives provide smooth, precise, displacement of lens along stainless steel dual rails 63-page Text/Manual.

Economically priced, it is complemented by a Manual of 16 Articles /Experiments with test data and illustrations including Fourier Transform photos obtained with these lenses. The FX l5/5F Fourier Transform System meets the needs of the experimentalist on a very limited budget with a unique combination of hardware and software for a wide variety of applications.
