BS-MP 355/690+(R)

Only for use with multiphoton. Reflects laser light >690 nm, and transmits light <690 nm to the non-descanned detectors.

5

BS-MP -760

Only for use with multiphoton. Reflects laser light >760 nm, and transmits light <760 nm to the non-descanned detectors.

6

Rear

For confocal imaging. Sends all light to the scan head.
