WS seriesCompact and thin, built-in high-sensitivity CMOS image sensor The mini-spectrometer WS series is a polychromator provided in a compact, thin case that houses optical elements, image sensor, and driver circuit. Spectrum data can be acquired by guiding measurement light into a mini-spectrometer through an optical fiber and transferring the measured results to a PC via the USB connection. The incorporation of a high-sensitivity CMOS image sensor achieves high sensitivity and low power consumption. Changes to the spectral response range and spectral resolution are also available as options. Moreover, the trigger function that can be also used for short-term integration enables spectroscopic measurement of pulse emissions. The product includes free evaluation software with functions for setting measurement conditions, acquiring and saving data, drawing graphs, and so on. Furthermore, the DLL function specifications are disclosed, so users can create their original measurement software programs. 3 Wide spectral response range (C16449MA-01) 3 High resolution 3 Spectral response range and spectral resolution can be customized (optional). 3 High-sensitivity CMOS image sensor built in (high sensitivity equivalent to that of a CCD) 3 With a trigger function 3 Shutter function 3 External power supply not necessary (USB bus powered) S- Applications 3 Film thickness measurements 3 LIBS (Laser-Induced Breakdown Spectroscopy) 3 Color measurement 3 Gas analysis When there is a temperature difference between a product and the surrounding area in high humidity environment, dew condensation may occur on the product surface. Dew condensation on the product may cause deterioration in characteristics and reliability. Note: Exceeding the absolute maximum ratings even momentarily may cause a drop in product quality. Always be sure to use the product within the absolute maximum ratings.

The difference between the ideal value and typical example contains a measurement error. The smaller the A/D output, the larger the measurement error. A/D output is the sum of the sensor and circuit offset outputs and the sensor dark output. Optical component...

Spectrum data can be acquired by guiding measurement light into a mini-spectrometer through an optical fiber and transferring the measured results to a PC via the USB connection. Since there are no moving parts inside the device, constantly stable measurements can be expected. Moreover, the optical guiding section uses an optical fiber making connection to the measured object flexible. In the C16449MA-01/-02, the following trigger operation modes are available. You can switch between these modes from the evaluation software supplied with the C16449MA-01/-02. Sensor operation (integration) starts...

Sensor operation (integration) starts when a trigger (high level or low level can be specified) is applied to the external trigger terminal, and then the digital data is acquired. Measure start Trigger signal Sensor state Idle Exposure | Data output Exposure | Data output Exposure | Data output | Idle Sensor operation (integration) period is determined by the width of the trigger (high level or low level can be specified) applied to the external trigger terminal, and then the digital data is acquired. Measure start In any of the modes 1 to 4, if the trigger input cycle is shorter than the measurement...
