Instruments since 2014
Cimel Sun photometers most recent version (CE318-T) include an new control unit with improved and additional features (e.g., microstepping for faster and smoother robot response, onboard data storage, lunar measurement scenarios, GPS, and communication via serial, USB, cellular, and DCP) and a new sensor head with an improved pointing device for tracking both sun and moon. The new system is compatible with previous robot versions.
It is available in 3 models (standard, polarized and Seaprism) (see Complete System Equipment Details).
The model firmware is upgradable using an on site or a remotely accessible PC.
Instruments From 2004 - 2014
Cimel sun photometers manufactured since 2004 have a new naming convention:
- CE 318N (new) (V, E,U) (B or P) (S or X) (1 - 9)
(Visible, Extended, Ultraviolet)
(Base or Polarized)
[Standard or other (X) filter arrangement]
(Number of filters installed by Cimel Electronique)
These Models had an improved sensor head optics design with onboard processing. Extended wavelength versions had a Hamamatsu (model G8421-05) InGaAs, or Indium gallium arsenide detector instead of a second silicon detector. These models use 5.2x(a-f) firmware.
Instruments Prior to 2004
Cimel sun photometers produced until 2004 were available in two 8-filter models:
- CE-318-1 Standard Model with 1020-870-675-440-936-500-340-380 nm filters
- CE-318-2 Polar Model with 1020-870P1-675-440-870P2-870-936-870P3 nm filters
where P indicates a polarized filter. These instruments have Hamamatsu detectors, an ultraviolet (UV) enhanced silicon detector for the sun collimator (model S1336), and a silicon detector for the sky collimator (model S2386). Firmware 4.8xb versions installed in these models include:
- 4.80b for VX1004 GMT data collection platforms
- 4.81b for VX1004/2 data collection platforms
