Lens Parameters

The following lens parameters are displayed in the Edit Lens Parameters window and can be edited:

Basic lens information

• Name: Names should provide unambiguous identification of the magnification and the viewing mode (video camera or Lucivid).

• Comments: (optional) Comments can help you identify the lens and its conditions of use; they are stored with the lens calibration file (.len filename extension).

• Units: the unit should be appropriate for the lens, typically micrometers.

Scaling Information

You can enter Scale Factor and/or Aspect Ratio in the corresponding field.

Display resolution is also shown, but is not editable

Lens Category

The lens category affects the calibration parameters, so it's important to set category appropriately:

• Camera or Image: lenses used with previously acquired images or with a camera
• Lucivid: Direct viewing through the oculars of the microscope

Z Correction factor

Radio buttons that correspond to common lens media auto-populate the Z correction factor. Alternatively, you can select User-Specified and type in the refractive index of the medium between the lens and the sample.
