ERROR: UndefVarError: SCHOTT not defined

[fortunewalla]

Describe the bug I managed to install OpticSim and tried to run the example given in the docs to test a success installation but I get the below error of SCHOTT not defined.

To Reproduce

https://microsoft.github.io/OpticSim.jl/stable/#Installation

Run this example to check that everything installed properly:

using OpticSim
Vis.draw(SphericalLens(OpticSim.GlassCat.SCHOTT.N_BK7, 0.0, 10.0, 10.0, 5.0, 5.0))
Vis.save("assets/test_install.png") # hide
nothing # hide

Expected behavior Example given to test installation should work.
