Remarks about the nodal point and the entrance pupil

In the second page dedicated to the entrance pupil - still often called nodal point - we'll see concretely how to find it - Find the entrance pupil

In this way the rim intensity may be kept constant over the entrance pupil of the objective (7,90).

How to set the Kalahari V2 head at the entrance pupil

The imaging optical system of the first channel has its entrance pupil far away from the mold tool.

The goal is to correct distortion errors caused by environmental influences like changes in temperature or pressure.

The entrance nodal point is thus different from the entrance pupil but it's around the entrance pupil you have to rotate the camera with the stitching method to get perfect overlaps.

Preferably, the optical relay assembly (130) is designed to form an image of the exit pupil of the spherical mirror assembly (110) in the entrance pupil (155) of the lens (145).

The inlet pupil (2) is the optical input of the device, while the inputs of the correction parameter input unit (6) are its key inputs.

The location of the entrance pupil and stimulus position on the retina can be moved independently.

Light reflected off of the back interior portion of the eye and through an exit pupil effectively located at the entrance pupil within the ring of light can be collected.

The beam can fill spatial modes at substantially all radii of the optical fiber entrance pupil.
