Have you considered purchasing a hollow prism and filling it with CS2 yourself?

CS2 -- which goes by the name carbon disulfide, or carbon bisulphide,
or similar variations -- is a pleasant-smelling liquid with a high
index of refraction.

It is often used in physics demonstrations or experiments involving light.


A typical laboratory demonstration is described here:


http://demoroom.physics.ncsu.edu/html/demos/246.html
Projected Spectrum with Prism



As you can see, the demonstration involves projecting "a slit of light
through a prism or hollow prism filled with carbon disulfide..."
(sulphide is sometimes spelled sulfide).



This is what is conventionally meant by a 'carbon disulphide (or
bisulphide) prism' -- a hollow glass prism filled with liquid CS2.


The prisms are not generally sold pre-filled with CS2, as this would
require extraordinary precautions to prevent leaks during shipping.


You can purchase a laboratory-grade hollow prism at many scientific
supply houses, such as:

Hollow Prism
CP32508-00
$80.47     
For Refractive Index Determination and Dispersion Work in Liquids 



Similarly, CS2 is a common laboratory chemical that can be purchased
from most chemical supply houses, such as:

Is this the sort of information you had in mind?

If so, what additional information do you need to make for a complete
answer to your question?

I want to cancel  my question.  I originally wanted to purchase
premade busulphide of carbon  prismfrom a catalog.  It is too late
now.
thank you
