Minimum deviation angle-based lens group clamp for measuring concentration of transparent liquid

The utility model discloses a lens group clamp for measuring transparent liquid concentration based on a minimum deviation angle, which comprises a rotating table, limiting clamping blocks are symmetrically arranged on the rotating table, and a first limiting area for placing a hollow prism is formed between the corresponding limiting clamping blocks; a first fixing plate is inserted into the rotating table, and a second limiting area used for clamping and fixing the reflective mirror is arranged on the first fixing plate; one side of the rotating table is connected with a second fixing plate, and a third fixing plate used for installing a CCD plate is inserted into the second fixing plate. According to the utility model, the rotating table is used as a mounting platform, and the second fixing plate and the third fixing plate are mounted on the rotating table, so that subsequent synchronous rotation along with the rotating table is facilitated, a stable lens group supporting condition is provided for subseque
