海洋光學(xué)研發(fā)了一種低成本，高性能的基于 CMOS（互補(bǔ)金屬氧化物半導(dǎo)體）傳感器的光譜儀。該光譜儀特別適宜于嵌入 OEM 設(shè)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(xiàn)絲毫不遜于大型系統(tǒng)。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(xué)分辨率。STS 是可見-近紅外光譜應(yīng)用的理想選擇，諸如對(duì) LED 的光譜光度及顏色測(cè)量和樣品的透射、吸收測(cè)量。并且它還是 OEM 應(yīng)用的理想選擇，特別是需要在線監(jiān)視一條或多條光譜線，又需要高重復(fù)性、穩(wěn)定性的結(jié)果的應(yīng)用環(huán)境中。
STS微型光纖光譜儀有350-800納米和650-1100納米兩種標(biāo)準(zhǔn)配置。大批量的 OEM 客戶還能自訂波長(zhǎng)范圍，入射孔徑和其他光學(xué)配件。與其他微型光譜儀不同的是，STS 自帶有內(nèi)嵌的光閘以實(shí)現(xiàn)暗背景測(cè)量。單獨(dú)定價(jià)的操作軟件提供了包括光閘控制等的光譜采集與分析功能。客戶也可以根據(jù)需要來(lái)訂制 STS 操作軟件。
STS微型光纖光譜儀的核心是一個(gè)1024像素的 CMOS 探測(cè)器，它位于一個(gè)交叉結(jié)構(gòu)的 Czerny Turner 光具座內(nèi)。該光具座的不同之處在于其特別設(shè)計(jì)的準(zhǔn)直鏡和聚焦鏡，以及每毫米600條刻線密度的光柵。其光學(xué)設(shè)計(jì)和的 CMOS 探測(cè)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(guò)定制的入射孔徑，能夠?qū)崿F(xiàn)小于1.0納米（FWHM）的光學(xué)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.
