CAS 140CT光度计
The CAS 140CT, already in its 3rd generation, is the most successful array spectrometer from Instrument Systems worldwide. These instruments combine high accuracy with an opto-mechanically robust design and a simple operation. The range of applications is thus correspondingly wide - from 24 hour, round-the-clock operation in manufacturing to use as a reference instrument in calibration laboratories.
Centerpiece of the CAS 140CT is the newly developed Crossed-Czerny-Turner spectrograph incorporating a high-end, back-Illuminated CCD detector. The spectrometer design thus effectively reduces stray light, resulting in significantly improved dynamic range and measurement accuracy.
The CAS 140CT is the only array spectrometer to include an optical density filter wheel, extending the measurable intensity range over 4 orders of magnitude. Measurements for both very weak and very strong light sources can thus be acquired fully automatically.
Features:
various models from 200 to 2150 nm
high-end, cooled, back-Illuminated CCD detector for highest sensitivity and signal stability
wide intensity measurement range via integrated optical density filter wheel
integrated shutter for dark current measurements
acquisition times in the millisecond range
optionally USB or PCI interface
software solutions for laboratory and manufacturing applications
Applications:
system solutions for testing LEDs, displays und flash lamps
spectroradiometry in the UV-VIS-NIR range
universal spectrometer for laboratory applications
industrial quality control in the production line
