Diffraction Gratings for Microplate Reader
~ Enhance spectroscopy measurements with Shimadzu’s Sophisticated technology ~
Shimadzu contributes to Spectroscopy of Microplate Reader field by providing Hi-precision Diffraction Gratings.
What Can Affect Measurement Accuracy? : "Stray Light"
Monochromator-type microplate readers typically use diffraction gratings as their dispersive element. Since monochromator-type readers require precise wavelength selection, stray light can significantly impact measurement accuracy. If the selected wavelength contains a lot of stray light, it acts as noise, leading to low measurement accuracy. To improve measurement accuracy, it is effective to select diffraction gratings with low stray light, in addition to designing the entire monochromator that suppresses stray light.
Shimadzu Diffraction Gratings : Low Stray Light and High Diffraction Efficiency
Shimadzu diffraction gratings are produced by precisely replicating from the master gratings with extremely low stray light which are made by the holographic exposure method. Shimadzu is also the first company to establish the technology for manufacturing blazed holographic grooves, which ensure low stray light compared to conventional mechanically ruled gratings, while maintaining high diffraction efficiency. Shimadzu diffraction gratings are highly regarded for their low stray light, and have contributed to improving the measurement accuracy of many types of spectroscopic analyzers.
