Mini-spectrometer TM series
C10082MD, C10083MD
Integrating optical system, image sensor and circuit
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.

*1: A conversion factor for converting the im age sensor pixel num b er into a w avelength is recorded in the m odule. A calculation
factor for converting the A /D converted count into the input light inte nsity is not provided.
*2: D epends on the slit opening. Values w ere m easured w ith the slit opening listed in the table.
*3: M easured under constant light input conditions
*4: W hen m onochrom atic light of the follow ing w avelengths is in put, spectral stray light is defined as the ratio of the count
m easured at the input w avelength, to the count m easured in a regio n of the input w avelength 40 nm .
C 10082M D : 500 nm , C 10083M D : 650 nm
*5: E ntrance slit aperture size
*6: N o condensation
Light spectrally separated by a grating is focused according to ligh t w avelength on predeterm ined im age sensor positions, and
high-order light is also input onto positions at integer-m ultiples of w avelength s.
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 follow ing w avelengths.
C 10082M D : N ear 340 nm and 500 nm , C 10083M D : N ear 500 nm and 700 nm
Types not using a high-order light cut off filter are also available. P lease specify by adding “-01” to the type num ber w hen ordering.
