Performance Advantages of Concave Grating Optics in Compact Fiber Optic Spectrometers
Jul 29, 2016 | News
Most plane grating optics utilize several mirrors in order to properly image the spectrum on the detector. With applications that require the use of UV light, especially UV-Vis absorbance, fluorescence, and solar radiometry, multiple mirrors can be detrimental to the performance of an instrument. The use of a holographic concave grating can eliminate the sensitivity issues and provide other benefits including: stray light reduction, aberration correction, thermal stability, and improved ruggedness.
