Polaroid XR-7 Land Diffraction Cassette is a specialized instant film cassette developed for X-ray diffraction and crystallography applications. Designed to accept 4 × 5 inch Polaroid Land film, the XR-7 was widely used in research laboratories, universities, and materials science facilities to capture Laue diffraction patterns for crystal orientation, metallurgy, and X-ray analysis. The cassette incorporates an internal lead-backed fluorescent intensifying screen that converts incident X-rays into visible light, allowing self-developing film to record diffraction images quickly and conveniently.
