Introduction

Optiland is a Python-based, open-source lens design and analysis framework. With a simple and intuitive Python interface, Optiland enables the design, optimization, and analysis of complex optical systems, from paraxial and real raytracing to polarization, coatings, and wavefront analyses. It supports 2D/3D visualization, comprehensive tolerancing, local and global optimization, and freeform optics, among other features. Built on the speed of NumPy and SciPy, Optiland delivers computational efficiency and flexibility across a wide range of optical tasks.

Get started immediately with Optiland Tutorial #1, see the extensive Learning Guide, or read the full documentation at Read the Docs.

U.S. patent 2959100

Python code to generate this 3D visualization:

from optiland.samples.objectives import ReverseTelephoto
lens = ReverseTelephoto()
lens.draw3D()

Documentation

Installation

You can install the package using pip. To do so, follow these steps:

  1. Open a terminal or command prompt.

  2. Run the following command to install the package:

    pip install optiland

Functionalities

  • Lens entry
  • 2D/3D visualization
  • Paraxial and aberration analyses
  • Real and paraxial ray tracing, including aspherics and freeforms
  • Polarization ray tracing
  • Real analysis functions (spot diagrams, ray aberration fans, OPD fans, distortion, PSF, MTF, etc.)
  • Glass and material catalogue (based on refractiveindex.info)
  • Design optimization (local and global)
  • Wavefront and Zernike analysis
  • Tolerancing, including sensitivity analysis and Monte Carlo methods
  • Coating and surface scatter (BSDF) analysis
  • Zemax file import

The code itself is in constant flux and new functionalities are always being added.

Roadmap

Optiland is continually evolving to provide new functionalities for optical design and analysis. Below are some of the planned features and enhancements we aim to implement in future versions:

  • GUI (based on Qt Quick)
  • Multiple Configurations (Zoom Lenses)
  • Thin Film Design and Optimization
  • Diffractive Optical Elements
  • Jones Pupils
  • Apodization Support
  • Additional Freeforms (Superconic, Zernike, etc.)
  • Image Simulation
  • Huygens PSF & MTF
  • Interferogram Analysis
  • Additional Tutorials/Examples
