Trouble

5. Photomicrography

a) The picture is out of focus.

b) The edges are blurred.

c) The viewfinder image does

not look sharp.

d) A room window or fluorescent

lamp was also shot.

Cause

You are using the OM camera with the

shutter speed set faster than 1/2 sec.

You are using an achromatic objective.

This type of objective cannot bring edges

into sharp focus.

The correction collar of the LWDCDPlan

40XPL-6 is not adjusted.

Stray light entered through the eyepieces

or the camera's viewfinder.

Remedy

Use the ND filter and select a slower shut-

ter speed.

Use a Plan objective when necessary.

Adjust the correction collar according to

the thickness of the vessel bottom.

Cap both eyepieces and the camera's

viewfinder.
