Photometer - SPECTRA
3000
SPECTRA 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*).

Convince yourself by
this new type of photometer! Easy to handle, reliable and compact.

ATX offers also a photometer for spectral
transmission measurement for flat materials like optical filters
a size up to 6" x 6" - SPECTRA transmission
