Titan Tool Supply Inc. has introduced the AME-5M 10× angle-measuring eyepiece for microscopes. Using a rotary vernier and rotatable crosshair, it measures 360° to an accuracy of 5 min. The eyepiece fits all 23-mm optic tubes, including eight models of the company’s microscopes, and can be supplied with optional bushings to fit 30-mm or larger optic tubes. The white scale on a black background is easy to read and enlarged by a 10× magnifier. Applications include checking cutting tool geometry and angular measurements in die- and mold-making, R&D and quality control.
