spectraval 1501-focus

Spectroradiometer for small objects

JETI spectraval 1501-focus spectroradiometer is used for spectral radiance measurement. It can be applied for the measurement of small light emitting objects as LED chips, the segments of alphanumeric displays, back illuminated signs and mini CCFL tubes. In contrast to the standard device spectraval 1501, the spectroscopy instrument can be used in combination with add-on optics accessories to measure diameters of 3 mm, 1 mm and 0.5 mm in defined distances. The 0.5 mm version will be adjusted with a magnifying glass to increase the positioning precision.

All optics can be attached easily to the basic instrument by screwing. The used version of the front-end is automatically detected by the instrument and the appropriate calibration data set will be applied.

The focus device consists of the basic model and the focus add-on. This means that to obtain a focus device, please order the spectraval 1501 base model and the focus add-on (Article number: Focus Add-on).
