specbos 1201 - Spectroradiometer

specbos 1201 belongs to the smallest VIS spectroradiometers available worldwide (download datasheet (103kB)).

Its easy-to-use software has the full complement of radiometric and colorimetric functions requisite for research, diagnostic, and quality control applications.
The action spectrum for circadian effects due to suppresion of melatonin is implemented in the software. Furthermore the software calculates the Photosythetically Active Radiation (PAR), i.e. the number of photons emitted by a light source in one second regardless of their fequency.

Look and See! This new class of precision spectroradiometers is easy to handle, reliable and compact.

Measuring values:

Luminance, Radiance
Illuminance, Irradiance
xy and u'v' coordinates
Dominant wavelength
Color purity
Correlated Color Temperature
Color Rendering Index
Circadian metrics, PAR

To explore differences between specbos 1201 and the former model specbos 1200 see Application Note 4 at the Download-Section Application Notes.

Sort your LEDs with the LED Ranker.
For further information see LED Ranker site with demo video.

Both instruments can measure with spot sizes of 4 mm and more in luminance mode. For measurement of spots with less than 4mm diameter see our latest development - specbos 1201 focus.

Advantages:

USB powered - mobile!

Internal target spot laser

Excel spread sheets

Automatic measurement in selectable time intervals

Applications:

TV, Monitors, LCD-, LED-, Displays

Traffic lights, car lights

Room illumination

Lamp burn-in tests
