海洋光學研發了一種低成本，高性能的基于 CMOS（互補金屬氧化物半導體）傳感器的光譜儀。該光譜儀特別適宜于嵌入 OEM 設備中。雖然STS的體積很小，只有40mm x 42mm x 24mm，但是它的功能表現絲毫不遜于大型系統。主要特色：低雜散光的全光譜分析、高信噪比1500:1）和典型1.5納米 (FWHM) 光學分辨率。STS 是可見-近紅外光譜應用的理想選擇，諸如對 LED 的光譜光度及顏色測量和樣品的透射、吸收測量。并且它還是 OEM 應用的理想選擇，特別是需要在線監視一條或多條光譜線，又需要高重復性、穩定性的結果的應用環境中。
STS微型光纖光譜儀有350-800納米和650-1100納米兩種標準配置。大批量的 OEM 客戶還能自訂波長范圍，入射孔徑和其他光學配件。與其他微型光譜儀不同的是，STS 自帶有內嵌的光閘以實現暗背景測量。單獨定價的操作軟件提供了包括光閘控制等全方位的光譜采集與分析功能�？蛻粢部梢愿鶕枰獊碛喼� STS 操作軟件。
STS微型光纖光譜儀的核心是一個1024像素的 CMOS 探測器，它位于一個交叉結構的 Czerny Turner 光具座內。該光具座的不同之處在于其特別設計的準直鏡和聚焦鏡，以及每毫米600條刻線密度的光柵。其光學設計和先進的 CMOS 探測器提升了 STS 的性能，使之與昂貴的大型光譜儀相比毫不遜色。例如，STS 擁有14位 A/D，功耗僅為0.75w，通過定制的入射孔徑，完全能夠實現小于1.0納米（FWHM）的光學分辨率。 這也是 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.
