Mini-spectrometer
TM series
C11697MB
Trigger function and a high sensitivity
CMOS image sensor included
The C11697MB is a polychromator integrated with optical elements, an image sensor and a driver circuit. Light to be mea-
sured 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. The C11697MB is a mini-spectrometer with a high-sensitivity
CMOS image sensor mounted on the optical system platform of the previous type C10083MD. The trigger function accepts
even short-time integration so emission spectra from pulsed light can be measured. The readout time is drastically reduced,
making the C11697MB ideal for LED test on industrial productions lines.
The C11697MB comes supplied with free evaluation software that allows setting measurement conditions, acquiring and
saving data, and displaying graphs. Original measurement software can be designed on an end-user’s side as DLL’s function
specification is disclosed.

*2: Depends on the slit opening. Values were measured with the slit listed in the table “ Structure”.
*3: Measured under constant light input conditions
*4: When monochromatic light of 650 nm is input, spectral stray light is defined as the ratio of the count measured at the input
wavelength, to the count measured in a region of the input wavelength ±40 nm.
