s Connection example (transmission light measurement)

Light to be measured is guided into the entrance port of RC

series through an optical fiber and the spectrum measured

with the built-in image sensor is output through the USB port

to a PC for data acquisition.

There are no moving parts inside the unit so stable mea-

surement are obtained at all times. An optical fiber that

guides light input from external sources allows a flexible

measurement setup.

s Light input method

For C9407MA and C9409MA, an SMA connector (plug) is

attached with the other end of the optical fiber. Light can be

easily guided by hooking up this connector to the SMA recep-

tacle of an external unit. If the optical fiber connected to

C9407MA and C9409MA is shorter than needed, an optical

fiber of the desired length can be added by connecting a

relay unit.

s Electrical connection with a external circuit (C9409MA)

The flexible printed circuit board protruding from the head or module is used make electrical connections to an external circuit.
