1: OOIIrrad-C Overview

These variations in efficiencies and sensitivities indicate that most systems are unique. In measurements
such as absorbance, transmittance, reflectance, or reflectance color, the absolute response is not crucial
because the nature of those measurements is based on relative measurements of light with and without a
sample. A reference measurement without the sample is taken and compared with a measurement taken
with the sample. With irradiance measurements, this is not possible because there is no sample that can be
removed for a reference measurement. A way is needed to create a conversion from raw readings (counts)
into real life measurements such as Joules and Watts. This conversion factor (calibration) is created by the
OOIIrrad-C application.

With OOIIrrad-C, you can obtain photopic data (in either lumens or lux per unit area) based on a CIE
standard visibility curve. You can also control the parameters for all system and display functions, such as
data acquisition, graph display, and cursor configuration. In addition, you can create a spreadsheet display
of lamp output intensity by wavelength, providing an easy way to chart and analyze acquired data.

The OOIIrrad-C application is under constant update and improvement. You can obtain free updates at
