美國(guó)CRAIC Technologies
美國(guó)CRAIC公司是研究及生產(chǎn)顯微分光光度分析系統(tǒng)的領(lǐng)導(dǎo)者。美國(guó)CRAIC公司生產(chǎn)的QDI系列顯微分光光度分析系統(tǒng)采用了科研級(jí)顯微鏡，科研級(jí)圖像采集探測(cè)器及科研級(jí)光譜分析儀。
CRAIC公司是目前世界上唯一使用科研級(jí)致冷數(shù)碼圖像采集探測(cè)器的顯微分光光度分析系統(tǒng)生產(chǎn)商。
CRAIC顯微分光光度分析系統(tǒng)結(jié)合了顯微學(xué)及光譜學(xué)的優(yōu)勢(shì)，集多種光譜技術(shù)于一身，實(shí)現(xiàn)了對(duì)顯微樣品的無(wú)損光譜測(cè)量及光譜分析，是普通光度計(jì)無(wú)法辦到的。目前已用于石油，煤炭，生物學(xué)，半導(dǎo)體科學(xué)，材料科學(xué)，工業(yè)質(zhì)量控制及刑事科學(xué)等。
CRAIC QDI 系列顯微分光光度分析系統(tǒng)以其無(wú)以倫比的質(zhì)量性能，簡(jiǎn)單易用的操作界面及專業(yè)化的售后服務(wù)為顯微學(xué)及光譜學(xué)開辟了嶄新的應(yīng)用空間。
CRAIC QDI 系列顯微分光光度分析系統(tǒng)不僅能獲得顯微樣品的高質(zhì)量圖像，還可以對(duì)顯微樣品進(jìn)行全光譜（紫外-可見-近紅外）定性定量測(cè)量分析。光譜范圍可從200nm延伸到2100nm。而且可用多種方式測(cè)量：
l 透射或吸收
l 反射
l 熒光
l 偏振
美國(guó)CRAIC 公司還與客戶密切溝通，開發(fā)出了UVM系列全光顯微鏡。
美國(guó)CRAIC 公司的全光（紫外－可見－近紅外）顯微鏡專為獲得常規(guī)顯微鏡無(wú)法得到的顯微圖像而設(shè)計(jì)。紫外－可見－近紅外顯微鏡具有亞微米級(jí)分辨率，能夠?qū)ι钭贤夂徒t外波段成像。具有很強(qiáng)的適應(yīng)性，集多種先進(jìn)的顯微成像技術(shù)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.
