The SM242/SM442 is a new compact design CCD Spectrometer for use with a PC. Based on SP's special optical bench design, it supports many different applications where spectral or color measurements are required, including high dynamic range applications. The SM242/SM442 can accept light directly through its built-in slit or via optical fiber. The durable aluminum housing that encloses the SM242/SM442 provides stable optical bench operation over a wide range of temperatures. The standard sensor arrays used are the Sony ILX 511 for SM242 and the Toshiba TCD1304 for the SM442. The array driver electronics have been designed for highly sensitive yet stable operation. This array (in conjunction with our special UV coating process and customized order sorting filters) allows up to a 850nm measurement window from 200nm to 1050nm (smaller measurement window sizes increase spectral resolution and light sensitivity). Thanks to the more pixel numbers, the SM442 is more preferable for the applications requiring higher resolution. The better sensitivity of the CCD makes the SM242 more suitable for the applications with lower light signals. Standard interface to the SM242/SM442 is a USB 1.1/2.0 compatible interface with 16-bit extended dynamic range. Our USB board can support multichannel configuration up to 8. With this multichannel configuration, a higher resolution for wide range or a dual spectrometer system (one for measurement and the other for reference) is possible. Spectral Products applies new UV enhancing coating on the CCD to increase the UV sensitivity below 450nm comparing with the conventional UV coating that is widely used in CCD spectrometers. By the help of this new UV coating, the signal sensitivity below 500nm can get improved ~20-50% more in general. The SM242/SM442 is a pre-configured model so if the desired wavelength range matches one of the standard wavelength ranges, SP can ship the unit within a couple of days.

Software support includes a SDK and DLLs for dedicated applications development and our SM32Pro Windows-based spectral acquisition and analysis software.
