CODE V (.seq) File Import Demo

This notebook demonstrates how to import a CODE V Sequential (.seq) file into Optiland using the load_codev_file function.

import os
from optiland.fileio import load_codev_file
from optiland import analysis

Loading a sample file

We will load a telescope objective lens from the Optiland test suite.

# Path to the sample CODE V file
file_path = '../../../tests/test_fileio/codev_files/telescope_objective.seq'  # located in test directory

# Load the lens
lens = load_codev_file(file_path)

# Display lens info
lens.info()

Visualizing the Lens

We can draw the lens layout to verify the import.

_ = lens.draw()

WARNING: No extinction coefficient data found for Daimon-20.yml. Assuming it is 0.

Analysis

Generate a spot diagram to assessment performance.

spot = analysis.SpotDiagram(lens)
_ = spot.view()
