SM245 Highspeed CCD Spectrometer

SM245: The Choice for High Speed Data Acquisition Applications


- Low dark noise and stray light
- Flexible optical input direct to slit or via fiber
- Designed from the ground up for a wide range of applications
- High speed data acquisition
- Standard design allows up to 200 - 1050nm range
- USB 1.1 / 2.0 interface with 16-bit
- Supports up to 8 USB multi-channel configuration
- New UV enhancing coating


Spectral Products is offering the new SM245 high speed 2048 pixel array CCD spectrometer. Thanks to the enhanced design on the electronic board of the SM245, the dark current noise level as well as the data acquisition speed have improved. Based on SP's special optical bench design, it supports many different applications where spectral or color measurements are required, including high speed data acquisition. The SM245 can accept light directly through its built-in slit or via optical fiber. The durable aluminum housing that encloses the SM245 provides stable optical bench operation over a wide range of temperatures. This array (in conjunction with our special UV coating process and customized order sorting filters) allows up to an 850nm measurement window from 200nm to 1050nm (smaller measurement window sizes increase spectral resolution and light sensitivity).

The standard interface to the SM642 is a USB 2.0 compatible interface with 16-bit. Our USB board can support multichannel configurations up to 8. With this multichannel configuration, a high resolution for a wide range or a dual spectrometer system (one for measurement and the other for reference) is possible.
Spectral Products applies a new UV enhancing coating on the CCD to increase the UV sensitivity below 450nm, compared with the conventional UV coating that is widely used in CCD spectrometers. With the help of this new UV coating, the signal sensitivity below 500nm can get improved ~20-50% more in general. Software support includes an SDK and DLLs for dedicated applications development and our SM32Pro Windows-based spectral acquisition and analysis software.
