Is there an image viewer capable of displaying images in .is2 file format?

These images were taken using a Fluke termographic camera.

At Fluke's site they offer their Smartview software for this kind of images, but I'm searching for a free (as in "free beer" ;-) alternative.

Could you not convert the image to a different type? i.e. JPG or TIFF if you want to keep the quality. – Bali C Mar 14 '12 at 9:38
Verboten -- This is asking for a software recommendation. – Daniel R Hicks Oct 2 '12 at 23:30

Fluke SmartView is the program to use, as this file type is proprietary to Fluke

as here is mentioned
The default software that works with is2 file format:

IRT Cronista
Company or developer: GRAYESS Inc.`

The format isn't unique to fluke. This is a better link. – txyoji May 15 '13 at 1:16
