Apply to infinity-corrected optical system, this objective and tube lens together form a compound objective lens system that produces an intermediate image at a finite distance within the microscope tube.
Coma, spherical aberration, and chromatic aberration have been well corrected.
40X and 100X are spring-loaded objectives, spring force<4N,have passed national standard test.
All lens are manufactured by precise processing and tested strictly, the surface quality controlled at least 40/20, form regularity test by Olympus interferometer, and controlled in 0.2.
Used with tube lens (focal length 180mm) together.
100x objective is immersion lens.
The design of objective lenses’ shells could be changed as your preference.
