Setting the Correction Collar

A culture microscope is designed to observe specimens contained in

vessels of various bottom thicknesses. In order to achieve optimum

objective performance of the culture microscope, the high N . A . objec-

tives are provided with a correction collar @. (Available on the

LWDCDPlan40XPL-6 only.)

The correction collar is effective with a vessel bottom from 0 to 2 mm

thickness.

1. If the thickness of the vessel bottom is known:

Match the correction collar to the thickness of the vessel bottom using

the collar scale provided.

2. If the thickness of the vessel bottom is unknown:

The optimum position for the correction collar can be obtained from the

image resolution. If a satisfactorily sharp image is not obtained after fo-

cus adjustment, rotate the correction collar to the right and left so that

you can compare the images at both sides. Reset the collar to the better

image, then starting from this position, further rotate the collar to the right

and left until both images can be obtained for comparison. By repeating

this procedure several times, you will find best position for the correction

collar. Refocus after rotating the correction collar.
