Mini-spectrometer TM series
TM series mini-spectrometers are polychromators integrated with optical elements, an image sensor and a driver circuit. Two models are
available: C10082MD (TM-UV/VIS-MOS) and C10083MD (TM-VIS/NIR-MOS). Light to be measured is guided into the entrance port of TM series
through an optical fiber and the spectrum measured with the built-in image sensor is output from the USB port to a PC for data acquisition. No
external power supply is required since USB bus power is used for circuit operation. The TM series comes with sample software, device driver
and DLL. The sample software lets you easily set measurement conditions, acquire and save data, and display graphs.

Light spectrally separated by a grating is focused according to light wavelength on predeterm ined im age sensor positions, and
high-order light is also input onto positions at integer-m ultiples of wavelengths.
In these m ini-spectrom eters an optical filter is attached to the im age sensor to cut off high-order light, but this also causes a drop
in the im age sensor output at the following wavelengths.
C10082M D: Near 340 nm and 500 nm , C10083M D: Near 500 nm and 700 nm
Types not using a high-order light cut off filter are also available. Please specify by adding “-01” to the type num ber when ordering.
