Direct-Attach Shutter A good dark measurement is necessary for accurate results during transmission, absorption, reflection, irradiance, or color measurement at different integration times Taking this dark measurement often leads to having to undertake manual actions, like covering the sensor or switching off the light This might be problematic with certain applications because of the time and place or operator restraints Our solution: a remote-controlled shutter positioned between the spectrometer entrance and the input fiber Avantes’ direct-attach shutter is the ideal accessory to facilitate the automatic shuttering of a spectrometer This shutter is operated via TTL pulses from an external source or an AvaSpec spectrometer through a cable (IC-DB26-AS SHUTTER-06, to be ordered separately) The DA-Shutter switch unit is directly attached to the spectrometer’s SMA input connector The fiber normally connected to the spectrometer is then connected to the DA-Shutter This switch unit and the power source, and the TTL control signal are connected to the control box The industrial-graded shutter motor used inside will support heavy usage of the instrument With its 5,000,000 cycles, 24/7 operation is supported in most cases To operate the DA-Shutter, a PS-12V/208A 12-volt DC power adapter is required (to be ordered separately)

Fiber Optic Multiplexer (FOM) To configure systems that enable a single light source and spectrometer to make multi-point serial measurements, Avantes offers the FOM fiber optic multiplexer The device is available in three different configurations: 1 input to 16 outputs, 2 inputs to 8 outputs or 4 inputs to 4 outputs The FOM consists of a precisely controlled stepper motor and a rotary block The optical path is coupled through multiple COL-UV/VIS collimating lenses The fiber-optic multiplexer is controlled via a USB connection to a PC The FOM software enables full control over the switching order, switching time, and delay time and operates as a stand-alone unit To integrate the FOM with AvaSpec spectrometers and your own devices, the FOM-DLL software development kit is available and should be ordered separately Applications for the FOM include process control, where multiple locations need to be measured with multiple probes, all with one spectrometer and/or light source
