SM240是紧凑型CCD光谱仪。它基于Spectral Product的SM200光路结构设计，支持很多应用，如光谱和颜色测量，大动态范围应用。

SM240可直接通过内置狭缝或经光纤耦合进光。可拆卸式接口可以使用标准SMA 905，FC或者定制光纤接口，亦可直连多种SMX系列的附件。SM240坚固的铝合金制外壳可以确保光路在大的温度范围内的工作稳定性。

SM240采用Sony ILX 511阵列探测器，探测器的驱动电路具有很高的灵敏度和稳定性。结合Spectral Product特殊的紫外镀膜工艺以及定制的消高级次颜色滤波片，可以提供850nm的测量范围，覆盖200nm到1050nm（缩短测量范围，可以提高分辨率和灵敏度）。SM240的设计允许采用定制阵列，如光电二极管组件和其它CCD阵列，以满足特殊应用。

光谱仪软件包括基于Windows的SM32光谱获取和分析软件，以及SDK和DLLs包供客户自行开发。标准USB接口设计同时支持编程数据采集和外触发。

The Choice for Spectral Applications

The SM240 is a compact CCD Spectrometer for use with a PC. Based on the SM200 optical bench design, it supports many different applications where spectral or color measurements are required, including high dynamic range applications.

The SM240 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 SM240 provides stable optical bench operation over a wide range of temperatures.

The standard sensor array used is the Sony ILX 511. The array driver electronics have been designed for highly sensitive yet stable operati This array (in conjunction with our special UV coating process and custom order sorting filters) allows up to a 850nm measurement window located from 200nm to 1050nm (smaller measurement window sizes increase spectral resolution and light sensitivity). The design of the SM240 also allows use of custom arrays for special applications, including photodiode assemblies and alternative CCD arrays.

Standard interfaces to the SM240 include a USB 2.0 interface with 16-bit extended dynamic range and a PCI card interface with 12-bit dynamic range. Custom interfaces and legacy ISA and PCMCIA interfaces are available.

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.
