Laser scanning confocal microscopy for 3D surface mapping
Lapšanská, Hana ; Schovánek, Petr
This contribution introduces a modern microscopic method and shows possible measurements and analysis of wire saw machined glass pieces. The main objective of realized measurements is to identify possible defects and its depth to propose eventual additional treatment. We are looking for the optimal technological procedure of grooved glass stick-on supports preparation. Such supports are used for the very thin accurate optical components production which is executed in our workshops and laboratories. Surface quality of the support significantly influences the quality of produced optical components.

FEM simulation of thermal differences in semi finished glass pieces during the cooling
Havelková, Martina ; Schovánek, Petr
Semi finished glass pieces are moulded in the furnace to template forms not only to fit their shape but also to reduce internal stresses. Thermal differences are unwanted and have to be minimized in the cooling procedure of the glass pieces. Simulations of various types and sizes of shaping forms and complex model cooling were accomplished. The aim of these simulations was to optimise geometric parameters, clamping conditions and material of the form, so that thermal differences at glass are minimized during the cooling.
