Increasing development of near-infrared (NIR) Fresnel lens

by: Ashton KIM
<Transmittance graph of NIR materials>   Recently, the development of Fresnel lens for near infrared ray is increasing.   Near infrared, also called NIR (Near Infrared), has various uses. Used in self-driving cars, Internet of Thing (IoT), Time of Flight (ToF), beauty and healthcare. Near infrared has a wavelength of 0.75 ~ 3um and has 12 times...

Glassy carbon mold for glass press molding upto 2000° C

by: Ashton KIM
Introduces the development of glassy carbon mold, which is 99.2% carbon, capable of glass press molding with high melting point glass upto 2000 ° C. In the past, the lens was thermoformed with low melting glass material by using DLC (Diamond-like carbon) to increase the heat resistance of the Tungsten-Carbide mold. At this time, cracks occur because the coefficient of...
