The Coax- Series is a series of telecentric lenses that meet the highest requirements with regard to functionality. Telecentricity combined with an exceptional high contrast, make these lenses ideally suited for demanding applications. With incident light these telecentric measuring lenses are perfectly suited to detect even the smallest defects.  


 Upon request the optics can be equipped with variable iris, polarizing filter and retarder plates; high-end optics for the most difficult surface inspections. 

The TZ Coax-Series covers linear magnifications from 0.5 to 3.0. Another accessoire for telecentric Coax-Series lenses are different illumination systems. Typically LED based illumination is used but fibres can be attached, too. 


Of course all lenses can be used without coax illumination as single stand alone telecentric lens.

In the table below you can see the available base lenses. Ask for special adjustment to fit your application needs perfectly.
