MRI 3030 VistaRanger Tele-Radiometer w/ Filter Wheel, Accessories Teleradiometer

Description

Being offered as surplus to the needs of
the United States Department of Interior, Bureau of Land Management, is this MRI 3030 VistaRanger Tele-Radiometer with Filter Wheel and Accessories.   Everything is housed in a wooden storage case and looks to be in very good condition.
Please refer to the pictures for details as to what's included.
I have a number of these units available, some with different configurations and I believe they may have been used in unison.  Feel free to email for more information.
Tele-Radiometers measuring atmospheric radiance of sky and natural targets can be used in a number of ways to yield approximations of atmospheric extinction.
I found a paper onthe internet that discusses results of a measurement program conducted near Meteor Crater, Arizona in which a transmissometer, teleradiometer measuring sky-target contrast of a nearly black artificial target, teleradiometer measurements of sky-target contrast of a natural tree covered target, and an integrating nephelometer were used to measure atmospheric optical parameters from which, through the use of appropriate models, atmospheric extinction can be extracted.  The teleradiometer used for natural target contrast measurements was a standard MRI 3010 Vista Ranger, while the teleradiometer used for the artificial black target, referred to as a precision teleradiometer, was a specially designed lo flare small angle of view instrument built by Optec, Inc.
