An optional set of test samples for the HSM60 Polariscope consisting of a Crane Hook, Spanner & Shaft. Specimens are made from CR39 photoelastic material which is a highly specialised reactive plastic polymer- commonly used in lens manufacture. A variety of specimens can be optionally supplied and each one in turn is mounted into the loaded mechanism using quick connect joints.
PLEASE NOTE: that the actual Polariscope samples are clear (transparent - no colour) apart from when force is exerted through them using the loading mechanism and viewed through the filter setup illuminated by the light box. Images are coloured (black) for visual ease.
