      The Choice for Spectral Applications

      The 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 SM442 can accept light directly through its built-in slit or via optical fiber. A removable faceplate allows the use of standard SMA 905, FC, and custom fiber connectors. This faceplate also allows direct attachment to dedicated systems and a number of SMX Accessories. The durable aluminum housing that encloses the SM442 provides stable optical bench operation over a wide range of temperatures.

      The standard sensor array used is the Toshiba TCD 1304. 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 increased pixel numbers from 2048 of old Sony CCD to 3648, the SM442 allows almost twice better resolution with narrower slit than the SM242.

      Standard interface to the SM442 is a USB 1.1/2.0 compatible interface with 16-bit extended dynamic range.

      The SM442 is a custom configuration model at the moment but will be a pre-configured model soon so that 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.
