Mini-spectrometer
C13053MA
FT series
Compact and thin, built-in high-sensitivity
CMOS image sensor
The mini-spectrometer FT (flat type) series is a polychromator provided in a compact, thin case that houses optical elements,
image sensor, and driver circuit. Spectrum data can be acquired by guiding measurement light into a mini-spectrometer
through an optical fiber and transferring the measured results to a PC via the USB connection. The incorporation of a high-
sensitivity CMOS image sensor maintains high sensitivity equivalent to that of a CCD and achieves low power consumption.
Moreover, the trigger function that can be also used for short-term integration enables spectroscopic measurement of pulse
emissions.
The product includes free evaluation software with functions for setting measurement conditions, acquiring and saving data,
drawing graphs, and so on. Furthermore, the DLL function specifications are disclosed, so users can create their original
measurement software programs.
