Green Trans PD calibration

(Alexa, Jax)

We calibrated the green trans PD, channel name H1:ALS-C_TRY_A_DC. 

At the photodiode, the power measured was 0.192 mW. The channel voltage read 2.9V with gain set to 20. The corresponding responsivity is 0.755 A/W.

We also installed a lens (PLCX-25.4-51.5-C-532) in front of this PD since beam size was comparable to PD size.
