摘要
We report a wide nematic range and low absorption loss chlorinated liquid crystal mixture, designated as IR-M2, for mid-wave infrared applications. IR-M2 is quite transparent in the 3.8-5.0 mu m window while keeping a high birefringence (Delta n similar to 0.194) in the infrared region and a modest dielectric anisotropy. For long-wave infrared applications, we propose another high Delta n chlorinated cyanoterphenyl compound.
