MODULE

Integrating optical system, image sensor and circuit

C10082MD, C10083MD

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.
