A Python library for simulating optical systems, similar to Zemax.

## Installation

Optika can be installed using pip:

```bash

pip install optika

```

## Features

- Sequential raytrace modeling

- Spherical, conical and toroidal surface sag profiles

- Ruled surfaces, constant, variable, and holographic line spacing

- Circular, rectangular, and polygonal apertures

- multilayer reflectivity and transmissivity

- n-dimensional configurations of the optical system using [named-arrays](https://github.com/sun-data/named-arrays)

- uncertainity propagation using [named-arrays](https://github.com/sun-data/named-arrays)

## Example Gallery

An [example](https://optika.readthedocs.io/en/latest/_autosummary/optika.systems.SequentialSystem.html#optika.systems.SequentialSystem)

of how to raytrace a Newtonian telescope using Optika:

Compute the [reflectivity of a multilayer mirror](https://optika.readthedocs.io/en/latest/_autosummary/optika.materials.multilayer_efficiency.html#optika.materials.multilayer_efficiency)

by specifying the materials and thicknesses of the layers.
