LAMBDA 1050/950/850 Spectrophotometers are advancing what's possible for your testing capabilities, whether it's measuring the absolute reflectance of coatings at various angles with our LAMBDA™ 950 or analyzing highly absorbing liquids with the LAMBDA 850. Now, with the LAMBDA 1050, we're pushing the limits even more.

The measurement of very small samples in transmission mode often poses problems. Large-scale losses of energy, scattered light and high backgrounds all impose severe performance requirements on UV/Vis and UV/Vis/NIR instruments. Using small beam apertures can lead to high background absorbance levels, often well over 2A.
幸运8平台彩票The accurate measurement ofspecular reflectance over a substantialrange of angles and a widerange of wavelengths from theUV through NIR is a prerequisite to the design and manufacture ofa wide variety of modern opticalcomponents. In designing a systemDesign Considerations for a VariableAngle Absolute Reflectance AccessoryFor the LAMBDA 950/850/650 UV/Vis/NIRand UV/Vis Spectrophotometers.
幸运8平台彩票We developed spectrophotometry accessories for measuring absolute reflection on highly reflecting samples, not only at near-normal incidences but also at oblique incidences for incident angles up to more than 80 degrees. The accessories are designed for use with a high performance UV/Vis/NIR industrial spectrophotometer and are widely used for the accurate characterisation of mirrors.
In materials research there is sometimes a need to scan high absorbance samples such as laser protection lenses, optical filters, and polarization materials. Such sample types often need to be measured across the whole UV, Vis and NIR ranges of the electromagnetic spectrum.
幸运8平台彩票An optical coating consists of a combination of thin film layers that create interference effects used to enhance transmission or reflection properties for an optical system. How well an optical coating performs is dependent upon the number of factors, including the number of layers, the thickness of each layer and the differences in refractive index at the layer interfaces. The reference grade high performance Lambda 1050 when fitted with the proper accessories becomes an ideal tool for the determination of optical thin film constants.
The primary goal of this technical note is to guide the user through the accessory selection process for different specular/ diffuse samples. This will be achieved by measuring identical samples with varying contributions of diffuse and specular reflection, on three different reflection accessories, and then comparing the spectra generated.
The LAMBDA™ 650/850/950 family of UV/Vis and UV/Vis/NIR spectrophotometers are purposedesigned to enable a wide range of sample types to be analyzed, no matter the shape or dimensions.
目前国内外建筑玻璃行业目前测量使用的玻璃光学性能的计算软件主要有Optic5 、Window 5 及美国PerkinElmer公司的ASSP Software（包括建筑玻璃、防护玻璃、色度、雾度等模块）等。
This note demonstrates the use of Hellma® linearity filters to study the linearity of the PerkinElmer® high performance LAMBDA™ instruments (LAMBDA 850, 950 and 1050) in the visible region of the spectrum.
幸运8平台彩票Many cosmetic products now incorporate sunblock components to protect the skin from harmful ultra violet radiation. These products can be identified by the SPF value quoted on the label. A large proportion of these blocking components are nanoparticles that protect the skin, not by absorbing the harmful radiation, but by scattering it away from the skin. The most commonly used are nanoparticles of zinc oxide and titanium dioxide. This paper will discuss a new method for characterization and quantitation of nanoparticles in sunscreens and cosmetics via the use of UV/Visible spectroscopy. The method utilizes a 150 mm integrating sphere equipped with center mount and is able to quantitate and compare the contributions of absorbance, large particle scattering, and nanoparticle scattering.
幸运8平台彩票Sunscreen protects skin by either absorbing or reflecting the harmful ultraviolet rays, preventing them from reaching the skin. Using sunscreen while exposed to the sun can greatly reduce the chances of damaging skin cells, and developing cancer. For this study the PerkinElmer® Lambda™ 1050 equipped with a 150 mm integrating sphere will be use to collect scatter transmission data for sunscreen placed on a tape substrate. Testing sunscreen on a tape model of human skin to calculate the SPF value is more convenient and economical than testing on human skin.
