Telecentric lens

Hi, I’m going to buy a camera and I’ve been proposed to get a c-mount telecentric lens.
Do you think this is better than the “standard” componon solution?
My sensor is 1/1.8.

I don’t know if this is still relevant, but what is the optical resolution of the telecentric lens and the pixel size of the sensor? Because it seems most telecentric lenses are limited when it comes to resolution.
