AGA

The AGA – Advanced Grazing Angle specular reflectance accessory is a novel design for quantitative measurement of spatially defined circular areas of thin films on reflective substrates. Traditional grazing angle accessories produce a sampling area which is elliptical in shape and non-uniformly illuminates the sample area. This large asymmetrical sampling area causes problems when quantitative analysis is to be performed on small sample areas. The angle of incidence is equal to 80 degrees.

• Quantitative measurement of small areas of thin films and mono-molecular layers
• Selectable sample dimensions as small as 1/8" and as large as 1/2"
• Fixed 80 degree angle of incidence
