C9404CA, C9404CAH, C9405CA
Mini-spectrometer TG series
TG series mini-spectrometers are polychromators integrated with optical elements, an image sensor and a driver circuit. 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. C9404CA, C9404CAH and C9405CA are high sensitivity mini-spectrometers employing a back-thinned
type CCD image sensor. Their sensitivity is about two orders of magnitude higher than CMOS types making them even more ideal for low-light-
level measurement. C9404CAH is high resolution type (resolution: 1 nm Typ.). Their products come supplied with free sample software that
allows setting measurement conditions, acquiring and saving data, and displaying graphs. Driver software and DLL are also supplied as
accessory items to allow the users to configure their own measurement software.
