Ap. Kiselev et al., CONVEX CONCAVE BLANKS FOR SINGLE-CRYSTAL SILICON OPTICAL-COMPONENTS, Soviet journal of optical technology, 59(11), 1992, pp. 698-699
This paper presents data on the basic laws governing the high-temperat
ure plastic deformation of single-crystal silicon disks under central-
annular bending conditions by a hemispherical punch in order to obtain
optical-component blanks for transfer optics.
