A low-reflectance acrylic (Perspex) sheet is marketed under the name
'Optium' by Viratec (see:
<URL:http://www.viratec.com/pr_acrylic.html>). The web site offers
various data sheets on   the product which, if correct, suggest that
it is a good ultraviolet absorber, has reasonable anti-reflection
properties, and that the residual reflected light is purple (like
most anti-reflective products).
