Let's take a look at the Rollei films, from a point of their infrared ranges. It's easy to say that most of the Rollei films are Aviphot Pan 80 or 200, or Kentmere 100 and 400 (RPX). However, there's a lot more going on, and it's pretty interesting, at least for me.
RPX 25: Aviphot Pan 80 / on Polyester / panchromatic / finished by Harman / NOT for the infrared range
Retro 80: Aviphot Pan 80 / on transparent Polyester (great for slides) / super-panchromatic / finished by Foma / for infrared (up to 750nm)
Superpan 200: Aviphot Pan 200 / clear Triacetate (great for slides) / panchromatic / finished by Foma / for infrared (up to 750nm)
Retro 400S: Aviphot Pan 200 / transparent Polyester (great for slides) / panchromatic / finished by Foma / NOT for infrared (limited to 730nm)
Infrared IR400: Aviphot Pan 400S / transparent Polyester (great for slides) / panchromatic with extended IR sensitivity / finished by Agfa-Geaert) / for infrared (up to 750nm)
Basically: if you are using Retro 80 or Superpan 200, they are going be contrasty at box speeds, but give them more light and yellow/orange/red filters, and they will get closer to normal, all while ready for infrared as well (with an R72 filter).
Retro 400S isn't as good as Superpan 200. And it's possibly not up to 750nm to make sure you are buying the Infrared 400 instead, which is a more versatile film all around, even under its infrared range.
Cool, Belgium, and thank you, Agfa-Gevaert!
