Hello, Secretary Dong, when will the biometric filter be commercially available on a large scale?

Crystal Optech: Dear investors, our narrow-band filters, diffractive optical elements, proximity light/ambient light sensors and other products can be used to realize biometric functions and have been applied in smart phones, TWS headphones, smart homes and other fields. In the future, the company will continue to pay attention to the development trend of the biometric industry, make good technical layout and product development, and strive for more market opportunities. Thank you!
