  Apply to finite optical system, In a finite optical system of fixed tube length, light passing through the objective is directed toward the intermediate image plane (located at the front focal plane of the eyepiece) and converges at that point, undergoing constructive and destructive interference to produce an image.

 

  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.

 

  100x objective is immersion lens.

 

  The design of objective lenses’ shells could be changed as your preference.
