TC3MHR-5MHR CORE PLUS series are large FOV telecentric lenses for the latest generation sensors up to 1.1” like the IMX304 and 4/3” sensors like the KAC-12040. They are specifically designed to accurately measure large objects in a reduced space. Inspired by catadioptric telescopes, their folded optical path allows large FOV imaging while keeping the overall footprint compact. The size reduction is up to 45% compared with other telecentric lenses on the market. The length and working distance of a telecentric lens strongly impact the size of a vision system. This is especially critical when a large FOV telecentric lens is used with a telecentric illuminator, as the overall dimensions of the system are doubled. For this reason the working distance of TC3MHR-5MHR CORE PLUS series has been reduced to make a measurement system as compact as possible.
