Mini-spectrometer TF series



Compact and thin, built-in high-sensitivity CMOS image sensor for Raman spectroscopy

The mini-spectrometer TF 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 used for short-term integration enables spectroscopic measurement of pulse emissions. The product includes 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.

-Compact, thin case
-Low stray light due to the adoption of a double grating, high spectral resolution 0.4 nm
- High-sensitivity CMOS image sensor built in
(high sensitivity equivalent to that of a CCD)
-With trigger function
-High throughput using quartz transmission grating
-External power supply not necessary (USB bus powered)
-Easy installation in devices
-Stores wavelength conversion factor* 1 in internal memory
*1: A conversion factor for converting the image sensor pixel number into a wavelength. A calculation factor for converting the A/D converted count into the input light level is not provided.
