Portable Reflectometer Sources

A reflectometer is a device which is capable of measuring the reflectance of aluminized surfaces. The staff at CAL Tech uses one to determine the reflectivity of the aluminum surface of the 200 hale mirror after a cleaning. I've been trying to find a source for a relatively inexpensve reflectometer but the only source I've found is a scientific paper on how to make one:

Anybody have any information on a reflectometer?

Well, I finally tracked down a hand-held portable reflectometer that can measure mirror coating reflectivity as well as scatter. It's been used on large observatory mirrors to determine reflectivity after cleaning or recoating and also as a unit to measure scatter:

I guess I'll have to contact the company to determine the cost of the unit :S
