Input-current noise is directly in the signal path, so the op amp should minimize that parameter. JFET- or CMOS-input op amps are a must. Also (if possible) the op amp's input capacitance should be small compared to the PIN photodiode's capacitance. If you use a high-quality PIN photodiode and an op

This is slightly lower than expected, although the discrepancy can be explained by the current running through
