Precise Mechanics II
FSI-TP2Acad. year: 2020/2021
The course “Precise Mechanics II” familiarizes students with basic construction parts of precise mechanics and optics. Special attention is paid to optical details and knots, their drawing, dimensioning and fixing in technical assemblies. Also dealt with is the computer tracing of ray through optical systems.
Learning outcomes of the course unit
The course enables students to acquire knowledge necessary for solving problems connected with movements within instruments and devices of precise mechanics with respect to kinematic and dynamic parameters of the system.
Students are expected to have knowledge and skills necessary for solving problems connected with movements within instruments and devices of precise mechanics with respect to kinematic and dynamic parameters of the system.
