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.
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.
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.
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 transmission properties of light are predicted by wave theory. One outcome of the wave properties of light is that waves exhibit interference effects. Light waves that are in phase with each other undergo constructive interference, and their amplitudes are additive. Light waves exactly out of phase with each other (by 180°) undergo destructive interference, and their amplitudes cancel. It is through the principle of optical interference that thin film coatings control the reflection and transmission of light.
Today’s plastics are some of the most used materials on a global volume basis. Broadly integrated into today’s industrial and commercial lifestyles, they make a major, irreplaceable contribution to virtually every product category.
In this compendium you will find a wide range of applications for polymers, plastics, rubbers and advanced materials. Discover how to put these applications to work for you simply and efficiently.
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.
All medicinal products need to be protected and packaged in containers which conform to prescribed standards. The quality of pharmaceutical packaging can have a significant impact on the performance of pharmaceutical products and can reduce shelf-life if the improper packaging is used. The USP chapter, <671>, “Containers – Performance Testing” provides standards for the functional properties of packaging systems used for solid and liquid oral dosage forms for pharmaceuticals and dietary supplements. This application note demonstrates the determination of spectral transmission of plastic pharmaceutical containers using the PerkinElmer LAMBDA™ 1050+ UV/Vis/NIR spectrophotometer, in accordance with USP <671>.
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.

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.
Advanced optical materials, nanomaterials, and manmade chemicals can go a long way toward addressing the most vexing issues of our day. In materials testing, there’s sometimes a need to characterize complex samples, such as laser protection lenses, architectural glasses, optical filters, and anti-reflective coatings. Whether you’re performing testing and analysis in specialty glass/glazing, virtual reality, optoelectronics, automotive, laser technology, or solar panels, we have the right solution for you with our high performance LAMBDA™ series and appropriate sampling accessories.
The Polymer Market consists of a huge diversity of manufacturers of industrial products running many different processes yet still facing similar challenges. There is more and more pressure to achieve high product quality and reduce costs in order to stay one step ahead of the competition.
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.
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.
UV/Vis and UV/Vis/NIR spectroscopy are well established analytical techniques being effectively applied across a wide range of industries. High-performance UV/Vis spectroscopy has expanded into new applications, especially in the life sciences. At the same time, in traditional application areas such as materials characterization, optics, coatings, glass, pharmaceutical QA/QC, and color control, UV/Vis spectroscopy has become more sophisticated, providing higher quality results faster and easier than ever. In choosing a UV/Vis system or one with added NIR (near infrared) capabilities, there are many considerations. Traditional specifications such as wavelength range or sensitivity are critically important. Yet other elements such as ease of operation, speed of analysis, sampling flexibility, maintenance, and long-term durability may be important in meeting current and future needs. This whitepaper examines these issues in detail and present some newly available options that can provide a stronger foundation for choosing your next UV/Vis or UV/Vis/NIR system.
