SPECTROPHOTOMETER COMPRISING TWO DETECTORS FOR OVERLAPPING WAVELENGTH RANGES

Номер: CA0002633502A1

A spectrophotometer has a first photodetector (24) and a second photodetecto r (25) which is displaced spatially from the first photodetector in the direction of increasing wavelength in the spectrum. At any given time the second photodetector receives light at a wavelength which is substantially greater than that being received simultaneously by the first photodetector a t that time. The first photodetector has a first range of wavelengths over whi ch it is operable and a first upper operating limit, and the second photodetect or has a second range of wavelengths over which it is operable and a second upp er operating limit, the second range overlapping the first range and the second upper operating limit being greater than the first upper operating limit. Th us the range of operation is extended, and data in two different ranges is processed simultaneously. The spectrophotometer comprises a housing (1) containing a light source (11), a monochromator (15, 16, 18) and the photodetectors ...
