Parfocalizing Objective Lenses; Correcting Chromatic Aberration Of The Lenses - Olympus BXC-CBB Instructions Manual

TIP:
The diopter adjusting matter of the camera adapter is different in each camera adapter.
For details of camera adapters, refer to the camera adapter instruction manual provided by us.

3.11.4 Parfocalizing objective lenses

Parfocalizing of objective lenses provides smother observation work flow even with frequent objective lens switch.
Parfocalizing is having objective lenses with the corresponding focal points all in the same plane.
For this purpose, a set of offset values of Z-stage position is recommended to be held in customer's system software.
If needed, calibrate the set of offset values in advance with e.g. a mirror specimen.

3.11.5 Correcting chromatic aberration of the lenses

Chromatic aberration must be corrected for each objective lens every time BXC-CBB system is installed to improve the AF
performance.
The following figure illustrates chromatic aberration. Chromatic aberration occurs between the observation light
(λ=550nm) and the laser light (λ=785nm).
For detailed correction procedure, refer to the application manual.
