Directional Reflection Measurements on Highly Reflecting Coatings

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.

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

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.

Visible Reflectance Spectroscopy of Human Skin: the use of CIE L*a*b* Color Analysis for In Vivo Ethnic Skin Characterization

This schema remains a recognized tool for dermatological research in classifying the response of human skin to visible light for the health and skin care industry. The Fitzpatrick Scale is a modernization of the older Von Luschan’s Chromatic Scale which uses a series of 36 opaque glass tiles to characterize skin color. Figure 1 shows the range of colors for human skin as described by Von Luschan’s tiles. The Fitzpatrick scale then groups these into six skin types: albino, fair, beige, Mediterranean brown, dark brown, and black.

Case Study

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

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.

Field Application Report

Measurement of Enhanced Specular Reflector (ESR) Films Using a LAMBDA 1050 UV/Vis/NIR Spectrometer and URA Accessory

To verify the performance of ESR films represents a measurement challenge for many commercial spectrophotometer systems. Not only are ESR films designed to achieve very high reflectance (>98% R) in the visible spectral range, but are required to achieve this high reflectance at any angle of incidence and under any state of light polarization. Therefore, the ESR films need to be measured with an absolute variable angle reflectance accessory combined with an automated polarization accessory.

Technical Note

Full Spectrum, Angle Resolved Reflectance and Transmittance of Optical Coatings Using the LAMBDA 950/1050 UV/VIS/NIR Spectrophotometer with the ARTA Accessory

We evaluated a 3M® visible mirror film for potential use in a new curved photovoltaic module using a LAMBDA 950 spectrophotometer with an ARTA accessory. In this application, the 3M® film must transmit near-infrared photons to the underlying silicon solar cells (where they will be converted directly to electricity) while reflecting visible photons to the focus of the module where they may be absorbed by, for example a wavelength-agnostic thermal absorber used to drive a heat engine.

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.
