Why Limit Yourself, High Performance UV\VIS\NIR Instruments

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.

Acquisition of High Quality Transmission Spectra of Ultra-Small Samples Using the LAMBDA 950 UV/Vis/NIR and LAMBDA 850 UV/Vis Spectrophotometers

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.

Directional Reflection Measurements on Highly Reflecting Coatings

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.

High Absorbance Scanning with the PerkinElmer LAMBDA 850 UV/Vis and LAMBDA 950/1050 UV/Vis/NIR Spectrophotometers

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.

Measuring Absorptance (k) and Refractive Index (n) of Thin Films with the PerkinElmer Lambda 950/1050 High Performance UV-Vis/NIR Spectrometers

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.

Reflectance Measurements of Materials Used in the Solar Industry

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.

Particle Characterization of UV Blocking Sunscreens and Cosmetics Using UV/Visible Spectroscopy

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.

A Spectroscopic In Vitro Method for the Calculation of Sunscreen SPF Values

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.

To remove the halogen lamp follow the steps below:
  1. Switch off the spectrometer and unplug the line power cord.
  2. Remove the lamp compartment cover.
    Lift vertically from the handhold on the rear of the Lambda 650/850/950. Press down the catch and push the cover off backwards on a Lambda 800/900, or to the left on the other Lambda instruments.
  3. If necessary, remove the lamp baffle by loosening and removing the two screws on the top of the baffle and lifting the baffle vertically upward.
    NOTE: Instruments made prior to January 1, 1997 may have a different type of lamp baffle as shown in Figure 2. This is held in place with the same thumbscrew used to hold the lamp in place. Loosen the thumbscrew just enough to allow the lamp baffle to be removed.
  4. Remove the lamp assembly from the bracket by slackening the thumbscrew and pulling the lamp mount vertically upward.
    Save the thumbscrew, as it will be used with the replacement lamp assembly.
  5. Carefully pull the white ceramic connector from the rear of the halogen lamp.
  1. Unpack the new lamp assembly, taking care to hold it only by the metal mount to prevent fingerprints on the lamp window.
    Fingerprints on the lamp window cause hot spots during lamp operation, which can lead to premature lamp failure.
  2. Attach the thumbscrew to the back of the new lamp assembly.
    Make sure you leave enough room so that you can slide the thumbscrew onto the mounting bracket.
  3. Carefully push the white ceramic connector firmly onto the pins on the base of the lamp.
  4. Slide the new lamp assembly with the thumbscrew attached onto the mounting bracket as shown below.
    Make sure that the notch at the base of the lamp assembly fits securely over the alignment stud on the mounting bracket, so that the lamp mount is flush to the mounting bracket.
  5. If necessary, wipe the lamp window with a soft cloth moistened with alcohol to remove dirt.
    The dirt would otherwise be burned in when the lamp is hot.
  6. Replace the lamp baffle and secure it into place.
  7. Replace the lamp compartment cover and plug the line power cord into the spectrometer.
