스펙트로포토메타 - SPECTRA 3000

(SPECTRO-PHOTOMETER)

 

Spectro Photometer - SPECTRA 3000

Transmission spectrum of filter glassSPECTRA 3000 (download datasheet (152kB)) is an easy to use instrument for spectral transmission measurement in the VIS region. It is specially suited for test cells of up to 10 mm optical path length and for flat materials like optical filters.

 

SPECTRA 3000 is offered in two versions:

The RS232 version supplied with a PC cable and a power supply. The instrument automatically detects the COM port. Thus problems during installation are avoided.

The USB version (under development) can easily be connected with an USB port of the PC and the measurement can be started immediately - a real plug and play solution. The device is bus powered.

 

The software package allows the measurement of spectral data as transmission and absorbance. Besides the display and management of spectra (hot links to Excel and ASCII files) further mathematical operations as first and second derivation are possible.

 

The optional software ATX SPECTRA color allows the measurement of color coordinates of samples (e.g. L*a*b*).
