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.
