This kit modifies the instrument to perform in the near-infrared, shifting its optimized operational window to cover the 650-1000nm range. This conversion allows you to investigate the spectral features of M-type stars, carbon stars, and Be stars with prominent lines in the near-IR.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eCorrecting IR Artifacts from 650nm to 1000nm\u003c\/h3\u003e\n\u003cp\u003eA successful conversion to near-infrared requires specific optical corrections. Two critical components achieve this: a new, angled camera ring corrects for chromatism inherent to longer wavelengths, while an included order filter prevents the overlapping of spectral orders to ensure clean, unambiguous data.
