Interferometers

 

 

Interferometers are illuminated by a source of infrared energy. In the interferometer, the infrared energy is split in to two beams, and then optically recombined. In this way, the two beams interfere with each other through a constructive / destructive process to produce a complex waveform. This waveform is directed towards the sensor surface of the instrument where it interacts with the molecules of the sample and where the wavelengths are selectively absorbed.

Products & Services
Infrared (IR) spectrometers measure the wavelength and intensity of the absorption of infrared light by a sample. Search by Specification | Learn more about Infrared Spectrometers
Interferometers measure distance in terms of wavelength and determine the wavelengths of light sources. Search by Specification | Learn more about Interferometers
Optical bandpass filters are designed to transmit a specific waveband.  They are composed of many thin layers of dielectric materials, which have differing refractive indices to produce constructive and destructive interference in the transmitted light.

Polarimeters determine the amount of polarization of light. Learn more about Polarimeters
Lasers are devices that produce intense beams of monochromatic, coherent radiation. The word "laser" is an acronym for Light Amplification by Stimulated Emission of Radiation. Search by Specification | Learn more about Lasers
