In the 8th meeting on observational techniques, key systems and advancements were discussed, focusing on filter systems such as Gunn filters, IR filters, and narrow-band filters. The session explored spectrographs and dispersive elements like prisms, diffraction gratings, and grisms, emphasizing high throughput and low-resolution spectroscopy. Notable insights included the use of cross-dispersed echelle spectrographs and multiplexing techniques in fiber spectrographs, specifically regarding LAMOST with its 3.5-4.9m mirror and 4000 fibers across 16 spectrographs at Xinglong Station.
