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.
Python code to generate this 3D visualization:
from optiland.samples.objectives import ReverseTelephoto
