2p-RAM main optical path
Accessory path
General description: The accessory optical systems of the 2p-RAM couple through a 52 x 72 x 1 mm dichroic/mirror that is placed in the 2p-RAM detection path. This optic can be moved in and out of the optical path with a motor. Its size does NOT support the full FOV and NA of the 2p-RAM imaging or detection paths, but the full FOV is supported at a reduced NA. All light to/from the accessory optical systems goes through the 2p-RAM primary dichroic, so must have a wavelength shorter than the prim dichro cutoff (currently ~720nm) for efficient transmission. The main 2p-RAM tube lens is not part of the accessory optical systems path, so an accessory tube lens is used. All accessory optical systems are light-tight, so little ambient light will enter the 2p-RAM detection path.
