美國CRAIC Technologies
美國CRAIC公司是研究及生產顯微分光光度分析系統的領導者。美國CRAIC公司生產的QDI系列顯微分光光度分析系統采用了科研級顯微鏡，科研級圖像采集探測器及科研級光譜分析儀。
CRAIC公司是目前世界上唯一使用科研級致冷數碼圖像采集探測器的顯微分光光度分析系統生產商。
CRAIC顯微分光光度分析系統結合了顯微學及光譜學的優勢，集多種光譜技術于一身，實現了對顯微樣品的無損光譜測量及光譜分析，是普通光度計無法辦到的。目前已用于石油，煤炭，生物學，半導體科學，材料科學，工業質量控制及刑事科學等。
CRAIC QDI 系列顯微分光光度分析系統以其無以倫比的質量性能，簡單易用的操作界面及專業化的售后服務為顯微學及光譜學開辟了嶄新的應用空間。
CRAIC QDI 系列顯微分光光度分析系統不僅能獲得顯微樣品的高質量圖像，還可以對顯微樣品進行全光譜（紫外-可見-近紅外）定性定量測量分析。光譜范圍可從200nm延伸到2100nm。而且可用多種方式測量：
l 透射或吸收
l 反射
l 熒光
l 偏振
美國CRAIC 公司還與客戶密切溝通，開發出了UVM系列全光顯微鏡。
美國CRAIC 公司的全光（紫外－可見－近紅外）顯微鏡專為獲得常規顯微鏡無法得到的顯微圖像而設計。紫外－可見－近紅外顯微鏡具有亞微米級分辨率，能夠對深紫外和近紅外波段成像。具有很強的適應性，集多種先進的顯微成像技術于一身。

CRAIC Technologies manufactures superior microspectrophotometers for science and industrial applications. We specialize in the UV, visible and NIR regions and pride ourselves in making the finest tools for the finest minds.

Since CRAIC's founding, our mission has been to become the leading provider of superior quality optical tools and superior support for the customers who use those tools. We manufacture the best quality microspectrophotometers and UV-visible-NIR microscopes and Raman microspectrometers bar none.

The Company

Since its inception, CRAIC has specialized in optical tools for the ultraviolet, visible, and near-infrared regions. Products include microspectrophotometers (also known as microspectrometers or microscope spectrometers) that is able to take spectra of samples smaller than a micron. CRAIC has also designed and built UV-visible-NIR range microscopes. Full spectral range fluorescence, transmission, and reflectance spectra and images can be acquired from any microscopic sample non-destructively and without contact with these tools. CRAIC manufactures both scientific grade systems in addition to specialized systems for industries such as semiconductor inspection and pharmaceutical metrology. CRAIC also makes NIST Traceable Standards, the only ones in the world specifically designed for microspectrophotometers, and specialized software packages.

CRAIC specializes in the following micro-analytical techniques:

UV-Visible-NIR microspectroscopy
UV-visible-NIR microscopy
Color microspectroscopy
Transmission microspectroscopy & microscopy
Reflectance microspectroscopy & microscopy
Fluorescence microspectroscopy & microscopy
Polarization microspectroscopy & microscopy
Raman microspectroscopy
Film thickness measurements
Spectral modeling

CRAIC has more experience designing, developing, manufacturing and installing microspectrophotometers than anyone. CRAIC is committed to maintaining the highest level excellence for its' products and service.
