​​SM241 NIR Laser Spectrometer

The Choice for Spectral NIR Laser Applications

 


- Less expensive alternative to Germanium or InGaAs systems
- Compact system can be handheld or securly mounted
- Flexible optical input direct to slit or via fiber
- High performance electronics
- Allows spectral measurements between 900 - 1650nm
- 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 detectors 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 plated 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 the applications measuring very narrow band-width 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 a 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.
