Development of a New Optical Wavelength Rejection Filter
... Typically the throughput is less than 10% for a double monochromator, even close to the grating blaze, and the throughput decreases to less than 3 % for a triple monochromator. In this report, we demonstrate the existence of a new tunable optical filter which is highly efficient and which can replac ...
