Lets say we have a sensor giving out readings in the range of 100mV-1V.
I want to calibrate these such that 100mV should correspond to 0V and 1V should correspond to 5V. All the readings in between 100mV & 1V, likewise should be mapped.
A non-inverting adder with a potentiometer on one input leg will allow you to adjust the input voltage offset. With appropriate feedback resistor, you can also get the gain desired. Is that enough information?
OpAmps can definitely be a choice for such a circuit.Sorry, I've gone a bit rusty with my knowledge, its been quite a while and have lost touch ! Feels good to get back !!

The reason people are confused about your request for information is because it's such a straight forward problem. Use an opamp with the specified gain. The input impedance, output impedance and signal frequency however decide what opamp you chose.
