Abstract
A specimen heating holder for side entry transmission electron microscopes is described. The holder permits specimen tilt about two orthogonal axes and has the capability of raising the specimen temperature to .about.1000.degree. C. A novel hinged electrical connection, resistant to fatigue, supplies, supplies power to a heater within the specimen cradle. Special low thermal conductivity cradle bearings minimize the required heater current and promote ease of assembly yet are sufficiently strong to make specimen loading easy.
