海洋光学研发了一种低成本，高性能的基于 CMOS（互补金属氧化物半导体）传感器的光谱仪。该光谱仪特别适宜于嵌入 OEM 设备中。虽然STS的体积很小，只有40mm x 42mm x 24mm，但是它的功能表现丝毫不逊于大型系统。主要特色：低杂散光的全光谱分析、高信噪比1500:1）和典型1.5纳米 (FWHM) 光学分辨率。STS 是可见-近红外光谱应用的理想选择，诸如对 LED 的光谱光度及颜色测量和样品的透射、吸收测量。并且它还是 OEM 应用的理想选择，特别是需要在线监视一条或多条光谱线，又需要高重复性、稳定性的结果的应用环境中。
STS微型光纤光谱仪有350-800纳米和650-1100纳米两种标准配置。大批量的 OEM 客户还能自订波长范围，入射孔径和其他光学配件。与其他微型光谱仪不同的是，STS 自带有内嵌的光闸以实现暗背景测量。单独定价的操作软件提供了包括光闸控制等全方位的光谱采集与分析功能。客户也可以根据需要来订制 STS 操作软件。
STS微型光纤光谱仪的核心是一个1024像素的 CMOS 探测器，它位于一个交叉结构的 Czerny Turner 光具座内。该光具座的不同之处在于其特别设计的准直镜和聚焦镜，以及每毫米600条刻线密度的光栅。其光学设计和先进的 CMOS 探测器提升了 STS 的性能，使之与昂贵的大型光谱仪相比毫不逊色。例如，STS 拥有14位 A/D，功耗仅为0.75w，通过定制的入射孔径，完全能够实现小于1.0纳米（FWHM）的光学分辨率。 这也是 STS 如此吸引人的原因所在。
Our new STS Microspectrometer is a remarkably small CMOS-based unit that is less than 50 mm square and weighs just over 2 ounces.
This ultra-compact spectrometer is ideal for OEM devices and provides full spectral analysis with low stray light and high signal-to-noise ratio.
STS boasts optical resolution of ~1.5 nm (FWHM) and is particularly suited for high-intensity applications such as LED characterization and absorbance/transmission measurements.
STS meets or exceeds optical resolution, stability, sensitivity and other performance criteria associated with larger, more expensive spectrometers. Plus, its built-in shutter makes taking dark measurements more convenient.
OEM Ready
For OEM applications, the STS features a price that matches its size. We also provide volume discounts for OEMs who qualify.
