The infinity-corrected objective lens is the main part of the microscope
Achromatic objective lens is very simple and cheap price, it has not only corrected of color aberration for blue & red but spherical aberration in green color.
Besides, Apochromatic objective lens had corrected 3 colors so get the high N.A and long working distance. This lens has a long working distance and high NA., parfocal length.
The infinity-corrected objective lens has longer working distance than general objective lens.
This system transfer to CCD come from the objective lens through the tube lens.
SPO has 5.0X(Magnification) and 95mm parfocal distance.
