Spotlight 400N结合先进的成像技术和全自动化,大大地提高生产力和加快解决的问题。近红外线光谱范围几乎不需要前处理，成像方便快速。设定光谱6.25 x 6.25μm或者25 x 25μm的像素分辨率，采集自定义的采样区域。线性探测器阵列移动采集数据,建立一个图像的速度高达每秒80像素——例如25 * 25像素大小。一个1 x 1毫米样本地区还是可以在不到1分钟采集完成，5 x 5毫米样本地区7分钟左右也可以完成。每个像素对应于一个高质量的近红外光谱,通过使用聚光灯Spotlight'的内置智能软件程序,样品的化学信息根据像素之间的差异显示出的图像表现出来，并且单个成分的分布可以快速显示出来。主要优势：

Introducing the PerkinElmer infrared imaging and microscopy systems family.
With Spotlight 400 FT-IR and Spotlight 400N FT-NIR imaging systems, you experience unprecedented, uncompromising data quality and clear, complete, highly detailed results from all your samples. Spotlight FT-IR systems are purpose-built for a wide range of demanding imaging applications. So you’re able to switch between sampling modes – standard transmission, reflection, ATR imaging, and more – with ease, and your images can be collected.
It’s not every day that a masterpiece is created. But how else does one describe a laboratory instrument that will dramatically improve the understanding of materials across an unprecedented range of industries. With the Spotlight™ 400, IR imaging just became faster, more efficient and more flexible than ever before. It is quite simply the most productive laboratory FT-IR imaging system in the world.
There is an increased interest in the microscopic analysis of samples using FT-IR variable-temperature microscopy or imaging. Application areas include polymer studies, pharmaceutical and food analysis and geological measurements. PerkinElmer offers two options for variable temperature analyses – Linkam variable temperature sample cell and the hot stage accessory.
Human hair is typically 50-100 µ in diameter, previous transmission and ATR studies of its cross section1,2 reveal three major identifiable regions.
Technology improvements and increased use has established chemical imaging as a means of providing information on certain critical quality parameters that is not readily addressable using other techniques.

The following data was obtained from a sectioned of tomato seed and analyzed using the PerkinElmer spotlight FT-IR imaging system. The section was placed onto a Barium Fluoride window and the infrared data was obtained in transmission mode.
There are many stomata (thousands per square centimeter) in the lower epidermis of plant leaves. Two crescent-shaped cells called guard cells, which are rich in chloroplasts, flank the stoma. Starch is produced in daytime by photosynthesis within the guard cells, not in adjacent epidermal cells.
FT-IR Microscopy quickly provides a unique fingerprint of a complicated material made up of multiple constituents. Another advantage of this technique is that it requires little or no sample preparation and that it can generate spectra in a matter of a few minutes.
Of the several types of counterfeiting defined by the WHO, this application note covers the case where the counterfeit is chemically very similar to the genuine product, containing active ingredient and excipients in the correct concentrations. Traditional techniques such as HPLC and NIR spectroscopy could not differentiate the genuine and counterfeit products. They both work at the macro level, so would show only that the concentrations of ingredients were very similar.
ATR FT-IR imaging offers users easy spectroscopic access to “difficult” samples which are hard to image in transmission or reflection, or which have confusing depth structure.
ATR FT-IR imaging with germanium crystals offers the potential for acquiring infrared spectral images at up to four times higher spatial resolution than is possible using conventional reflectance or transmission imaging.
A recent study has demonstrated that the accuracy of kidney stone diagnosis can be substantially improved by switching from conventional optical microscopy and contrast staining to infrared (IR) microscopy. There are over a dozen different types of kidney stone, and diagnosing the type is important because most effective treatment methods vary for each.
Analyses using infrared microspectroscopy; performed by the Michigan State Police Forensic; Science Division (MSPFSD); Lansing Laboratory; helped to win a triple murder conviction by matching paint from one victim’s clothing to the murderer’s car.
Among the FDA’s top reasons for product recall were problems with sub-potency and tablet dissolution. In addition, recent cases of cGMP violations have highlighted issues in tablet manufacturing. One area where industry is seeking to improve its processes is in the blending area.
