Axial chromatic aberration in near-infrared region (up to 850nm) has been corrected in CFI Apochromat NIR 40X/60X W to clearly observe the minute structure of a thick specimen. The CFI Plan 100XC W (NA 1.1, W.D. 2.5) is the world's first water dipping lens with depth-induced aberration correction. Because of its special correction ring, this lens can correct spherical aberration induced by imaging deep in tissue or by working at physiological temperatures. Consequently, it is ideal for IR-DIC imaging and confocal applications as well as Multi-Photon imaging. Alternating both the wavelength from visible to infrared and the illumination technique from DIC to Oblique Light are carried out simply by rotating the respective turrets.

Objectives mounted on the sliding nosepiece can be raised when switching magnifications. This prevents the objective from colliding with the manipulator or the chamber. The retraction distance is 15mm, so even a thick glass dish is protected. The lens top can be easily dipped (approximately 1mm) into the bath solution by using the lever to eliminate the risk of specimen disturbance.

Electrical noise has been successfully reduced by utilizing fiber illumination to bring light into the system from outside the cage and by connecting ground pins to all main parts of the microscope. Vibration noise has also been reduced by undertaking critical measurement and simulation analysis to improve microscope rigidity.
