Starting points for first question: Look into i1Pro (later models of the first generation), which can be had for $200-400. Combine with some free or $99 Windows/Mac/Android software [0] [1]. Second question: It is still too hard even to find CRI for most offerings. It's pretty much a "buy, test, return the ones you don't like" situation. If independent reviewers start publishing spectrograms and making YouTube/etc videos, perhaps the industry will move forward some day. 0: https://www.argyllcms.com/doc/instruments.html#i1p2 https://www.argyllcms.com/doc/instruments.html#i1p2 1: https://rmimaging.com/spectrashop_brochure.pdf https://rmimaging.com/spectrashop_brochure.pdf
