▎ 摘　　要

NOVELTY - An optical lens comprises 48-54 pts. wt. calcite, 11-16 pts. wt. soda ash, 8-12 pts. wt. nano-silica, 10-12 pts. wt. modified talc, 8-10 pts. wt. glass fiber, 8-10 pts. wt. pearl powder, 8-10 pts. wt. graphene microchips, 22-26 pts. wt. low-carbon steel fiber, 15-18 pts. wt. hexagonal boron nitride, 4-6 pts. wt. manganese powder, 4-6 pts. wt. zirconium oxide, 4-6 pts. wt. hafnium bromide, 0.5-1 pt. wt. boron oxide, 0.5-1 pt. wt. beryllium oxide and 1-2 pts. wt. calcium sulfate whisker. USE - Non-heating optical lens is used for thermal imaging. ADVANTAGE - The optical lens does not cause polarization phenomenon and surface heat drift, and low heat rate, and can be used stably, and enables thermal imaging at high temperature. The refractive index of the lens does not change at a high temperature of 600 degrees C. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of non-heating optical lens.
