STS微型光纤光谱仪Microspectrometer
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*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,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.
