Two in One Variable Angle ATR-Specular Reflectance Accessory
Specular Reflectance is a technique for analyzing transparent films which usually yield weak spectra by ordinary transmission techniques. Applications include surface coatings on reflecting substrates; film thickness measurements by interference fringes and reflectivity coefficient determinations of metals. The application is the determining factor when deciding which angle of incidence should be selected. A 30 angle of incidence is normally chosen for more routine samples which have coating thicknesses in the micrometer range. For very thin coatings in the nanometer thickness range, an 80 angle of incidence would be appropriate.

When sample thickness is unknown, the full range of specular reflectance analysis can be performed conveniently with the VeeMAX III, Variable Angle 30 - 80 accessory. Simply move the sliding lever on the graduated scale with 1 increments to the desired angle. Using the precision angle adjustment, the angle of incidence can be increased or decreased depending upon the sensitivity requirements of the sample. As the angle of incidence changes the depth of penetration and absorbance intensity....the angle is selected to optimize sensitivity. Measured absorbance is directly related to the depth of penetration controlled by the angle of incidence. Sensitivity can be further enhanced with the use of either a manual rotating wire grid polarizer or a automated wire grid polarizer.

The VeeMAX III is also available as an automated accessory. The automated version offers high performance and conveniently selects incidence angles that are programmed independently or simultaneously. Software is integrated to control motion and data acquisition.

Optional single reflection ATR top plates for depth profiling studies are a perfect add-on feature. Depth of penetration from 0.40 to 46μm can be achieved using the VeeMAX III, Variable Angle 30 - 80 accessory. This Two in One design is the most economical concept ever presented to the analytical professional performing ATR and specular reflectance analysis. It easily adapts when the need for either ATR or specular analysis develops which offers convenient flexibility. Scroll below for the ATR Product DataSheet and order details.
