|specbos 1211 is a miniaturized and fast broadband spectroradiometer covering the wavelength range from VIS(UV) to NIR (download datasheet). It can be used for various applications both in lab as well as in production. The instrument is available in a standard version for the wavelength range of 350 ... 1000 nm and in an extended UV version (specbos 1211UV) with 230 ... 1000 nm.
specbos 1211 can be delivered with various interfaces.
specbos 1211 can be used with a Netbook to allow mobile applications. Such netbook with installed software can be delivered optionally.
specbos 1211 can be used for measurements in Irradiance mode as well as in Radiance mode with measuring diameters beginning from 4 mm. The special model specbos 1211 focus can measure diameters of 3 mm, 1 mm and 0.5 mm in radiance mode.
If only one measuring mode is of interest, it can be ordered specbos 1211L (only Radiance mode) or specbos 1211E (only Irradiance mode).
The measurement of samples in Radiant flux mode is possible with specbos 1311.
Examples for applications are the following:
|The instrument can be operated with the intuitive measuring software JETI LiVal or with one of the application specific programs as CalMAN (spectracal), ChromaPure (Display Calibrations) or LightSpace (LightIllusion). Furthermore it is possible to implement the instrument into customer specific applications using the USB interface (virtual COM port) directly by the following ways:
JETI offers additional accessories for specbos 1211 to expand its applications. more ....
