The Movable Objective Microscope® (MOM®) is a two- or thee-photon microscope capable of imaging deep within living specimens when combined with an appropriate laser. The Sutter MOM was the ﬁrst scope to provide 3-dimensional objective movement and rotation allowing the specimen to remain horizontal and stationary. Many highly regarded imaging laboratories around the world use the Sutter MOM and we constantly work with our customers to adapt the design for their changing needs.
The MOM consists of two independent microscopes. The wide-ﬁeld half of the microscope consists of an Olympus vertical illuminator, Sutter Xenon arc lamp and camera mount to provide standard epiﬂuorescence. The two-photon side of the microscope provides the optical pathway for guiding the excitation laser light from the table up into the scanning galvanometric mirrors and then expanding the beam through the scan lens and directing into the back of the objective. Following twophoton excitation, the emitted photons are directed by a dichroic mirror immediately above the objective into the detection pathway. The main body of the microscope moves backwards on a rail system allowing easy access to the specimen prior to imaging.
