esis.flights.f2.optics.design_single(grid=None, axis_channel='channel', num_distribution=11)[source]#

Load a single channel of the ESIS-II design.

This model starts with design_guess() and modifies the grating yaw, radius, and VLS parameters to those found by Jacob D. Parker in July 2024.

Parameters:

  • grid (None | ObjectVectorArray) – sampling of wavelength, field, and pupil positions that will be used to characterize the optical system.

  • axis_channel (str) – The name of the logical axis corresponding to changing camera channel.

  • num_distribution (int) – number of Monte Carlo samples to draw when computing uncertainties

Return type:

Instrument

Examples

Plot a spot diagram for this design.

# Import this package
import esis

# Load this design into memory
instrument = esis.flights.f2.optics.design_single(num_distribution=0)

# Lower the number of field angles for clearer plotting
instrument.field.num = 5

# Plot the spot diagram for each field angle
fig, ax = instrument.system.spot_diagram()
