CircularDetector

class marxs.optics.CircularDetector(pixsize=1, **kwargs)

Bases: OpticalElement

A detector shaped like a ring or tube.

This detector is shaped like a tube. The form is a circle in the xy plane and and flat along the z-direction. While most CCDs are flat in practice, the CircularDetector simulates a setup that can follow the Rowland circle geometry exactly which is useful, e.g. to study the resolution of a spectrograph without worrying about the details of the detector geometry.

Parameters:

position, orientation, zoom, pos4dsee description of pos4d

The radius of the tube is given by the zoom keyword, see pos4d. Use zoom[0] == zoom[1] to make a circular tube. zoom[0] != zoom[1] gives an elliptical profile. zoom[2] sets the extension in the z direction.
