A - OVERVIEW
OCR-504 Configurations
All OCR-500 series instruments are defined using a model numbering system.
These numbers are composed of three fields containing four selectors, and
have the following format:
OCR-50x-tffm
Where:
x
NUMBER-OF-CHANNELS
4 (four channel radiometer)
7 (seven channel radiometer)
t
TYPE-OF-RADIOMETER
I (Irradiance)
R (Radiance)
I/R (coupled Irradiance and Radiance)
ff
FIELD-OF-VIEW
10 (10 degrees half-angle)
CS (cosine)
M
MEDIA
A (Air)
W (water)
For example, an
OCR-504-R10W
is an OCR-500 series instrument with four
radiance channels, each with a 10° half-angle FOV (Field-Of-View) and is
intended for in-water use.
Please note that not all OCR-504 models are physically equivalent. Several
different configurations have been developed, and are detailed in the following
sections.
