Mini-Spectrometers Provide Low-Light Measurements

The C9404CA, C9405CA, C10082CA, and C10083CA mini-spectrometers each combine a back-thinned CCD image sensor, quartz transmission grating and driver circuit within a compact body. Each model is supplied with a software package that includes measurement software, device driver, and DLL. At the UV end, the C9404CA provides sensitivity from 200 to 400 nm and has spectral resolution of less than 3 nm. In the UV to visible region from 200 to 800 nm, the C10082CA offers spectral resolution of about 6 nm. To cover longer wavelengths, the C10083CA provides a response range from 320 to 1000 nm and has spectral resolution of about 6 nm. For shortwave near-infrared measurements, the C9405CA delivers spectral response of 500 to 1100 nm with spectral resolution of less than 5 nm. To enhance overall usability, the new mini-spectrometers also provide high throughput, highly accurate optical characteristics, wide dynamic range, and a USB interface.
