Features of relay lens
This is a lens made to test the performance of and align the sensor of mobile phone cameras. When setting a target at a distance for the configuration of an inspection system, you must use too large a space.
In this case, even if you use the relay lens to configure the collimation system and set a target at a close range, you can have the same effect as that produced when doing the inspection at a distance.
