Assembly overview

The animation above shows you 4 major modules: left excitation arm, detection arm, sample stages, and right excitation arm, in recommended assembling sequence. This is only an overview - see the detailed instructions for each module for the latest components and their arrangement.

Left excitation arm

Optical design

Laser light from the fiber output is collimated by L1 and then redirected into the electrically tunable lens (ETL). A 1:1 relay reimages the ETL onto a galvo mirror (M4), which is placed at the back pupil plane of the excitation objective L5 (f=50 mm DSLR objective). Scanning the Gaussian beam along one axis generates the light-sheet illumination. The fold mirrors M1, M2, M3 make the system more compact and allow angular alignment of the laser beam.

Right excitation arm

Optical design

Optical design of right excitation arm is identical to the left, with the only difference that the collimated laser beam is directed to the right by flip mirror (REF) and passes through folding mirrors (REF) before entering the ETL.
