Currently TracePy has no way to approximate the chief or marginal rays. This would be used as both a cosmetic feature - to show the chief and marginal rays for a given optical system, and as a useful tool for functions such as spot diagrams which should be shown with points near the chief ray.

Right now TracePy only has support for 2d plotting of an optical system. Eventually it is necessary to have 3d plotting, but this is not a priority.

I see from the code that the ray class takes 'wvl' as an attribute, but how do we pass a new wavelength to ray? The call to ray_plane to create the ray bundle does not take 'wvl'. I've poked around and can't see how to do this.

Thanks

Right now you can only specify the index of refraction N. However, there are several public databases that contain glass types and their index of refraction as a function of the wavelength of incident light, usually in the form of coefficients for some given functional form. It is straight forward to implement this: find a comprehensive database containing glass types and their coefficients, create some function that takes a glass type and wavelength and outputs an index N, and allow a surface to have a variable index of refraction that calls this function when needed.

Currently you can only save a given geometry as a csv file, but you cannot load that csv file directly from TracePy. Also, the ability to load optics tables from other ray tracing software such as BEAM4 would allow us to validate TracePy's outputs

Some conics allow for exact solutions for ray tracing - situations where numerically solving for the intersection point of the ray and surface is extremely wasteful. This could offer significant speedups.

As an action of a geometrical object can either be reflection or refraction it is not possible to create a simple beam splitter.
I think this is an very important feature missing here.

Best regards

These curves would be very valuable for the optimizer, which currently only optimizes for the rms of a spot diagram
