What it is
How it works
General reference — not yet source-verifiedFourier Transform Infrared spectrometry operates by passing a broadband infrared beam through a sample and measuring the interferogram produced by a moving mirror inside the instrument's Michelson interferometer. The interferogram is then processed through a Fourier transform mathematical operation to yield a spectrum of infrared absorbance or transmittance as a function of wavelength or wavenumber.
The Spectrum 3 Optica FTIR uses this interferometric technique to characterize the optical properties of precision optics, coatings, and thin films. The instrument measures how infrared light interacts with the sample material, providing data on molecular vibrations, film thickness, and optical constants.
Where it fits in the process flow
General reference — not yet source-verifiedFourier Transform Infrared spectrometers for precision optics are used after the coating or thin-film deposition process to verify the spectral performance of optical components. The instrument is employed in quality control and characterization steps within optics manufacturing workflows.
The Perkin Elmer Spectrum 3 Optica FTIR is typically situated in a metrology or analytical laboratory environment rather than directly in the production line. Downstream processes are informed by the FTIR measurement results, which guide rework, rejection, or acceptance of the optical components.
Applications
General reference — not yet source-verifiedThe Perkin Elmer Spectrum 3 Optica FTIR is applied to the analysis of optical coatings, thin films, and surface layers on precision optics. Applications include measuring infrared transmission and reflection spectra of coated lenses, filters, mirrors, and windows.
The instrument is also used for identifying organic contaminants, verifying coating composition, and characterizing multilayer dielectric stacks in the precision optics and semiconductor optics sectors. The FTIR technique allows non-destructive evaluation of optical components across the infrared spectrum.
