Features

In addition to the standard lists of Type IV flat field and monochromator gratings, HJY currently produces specific aberration-corrected concave gratings to maximize performance for a given application. In that case, using proprietary ray-tracing software, we optimize performance: resolution, throughput and signal to noise ratio. We need following data from our customers:


spectral range
configuration of use: monochromator or spectrograph
numeral aperture (F number) or size of grating
maximum overall dimension or maximum focal length
desired dispersion
desired resolution
entrance slit width and height or source geometry
minimum deviation: in general deviation has to be
minimum to improve correction of astigmatism, so indicate possible minimum deviation when overall dimensions of source, sample chamber and detector are taken into consideration.
at exit: if monochromator, exit slit width and height, and if flat field, length of detector, height and width of pixel.
