- USB 2.0 interface with 16-bit dynamic range available
- Support up to 8 multi-channel configuration
The SM241 is a compact CCD-based spectrometer designed for NIR laser applications. Spectral Products' IR up-conversion phosphor CCD coating breaks the standard silicon-based CCD detector's array sensitivity barrier of 1100nm to allow spectral measurements up to 1700nm. This technology makes the SM241 a lower-cost alternative to Germanium or InGaAs systems. The SM241 optical bench includes oversized gold-coated mirrors and gratings to accommodate NIR light collection and analysis. Maximum spectral coverage with this spectrometer is 900 nm to 1700 nm (reduced coverage window size within 900-1700nm will increase spectral resolution and light sensitivity). But although the SM241 can measure up to 1700nm, due to its low sensitivity, it is limited only to use in applications measuring very narrow bandwidth and strong lights like lasers in this NIR range.
Standard interfaces include a USB 2.0 interface and a PCI card interface with a 16-bit extended dynamic range. Software support includes an SDK and DLLs for dedicated applications development and our SM32Pro windows-based spectral acquisition and analysis software. Both standard and legacy interface designs provide support for advanced acquisition programming and external triggering.
