Mechanical applications
The most common application of telecentric lenses is the measurement of precision mechanical parts. Many of them are components produced for the automotive industry, such as shafts, valves, pistons and other parts of the engine. Parts like tubes or extruded aluminium profiles are typically controlled off-line by dedicated machines. Telecentric lenses are frequently used to control the dimensions of smaller mechanical parts like:
- springs
- screws
- nuts
- washers
Milling or turning machines tools need to be measured by specific gauging devices, called "tool presetters", which make wide use of small telecentric lenses and collimated sources.
