Grazing Angle Objective
The unique optical design of grazing angle objective provides unsurpassed sensitivity for the HYPERION™ series FT-IR microscopes.
The Bruker grazing angle objective is designed for the measurement of small areas of coatings on metal surfaces. The objective has unique design features that give excellent sensitivity, good spatial resolution, and the ability to utilize polarized light.
The patented grazing angle objective utilizes a novel two-pass configuration, providing unsurpassed sensitivity for collection of data from monolayers or thin films. The infrared spectra of a alkyl thiol monolayer on gold. The top spectrum was collected from a 100 x 100 micron area, the middle spectrum from a 50 x 50 area. The bottom spectrum was collected from a 25 x 25 micron area and equates to a mass of less than 1 picogram. Thin coatings on metals, semiconductors, and insulators can be readily analyzed with the Grazing angle objective. Polarization integrity is maintained to ensure the highest quality results.
