Diamond-like Carbon coating (DLC for short) has good optical transparency and wide optical bandwidth. In particular, it has high transmittance and optical refractive index in the infrared and microwave bands.DLC coating can be applied on infrared optical lens and improve transmittance and hardness. Opticreate’s DLC coating has good uniformity, the power of substrate is basically same before and after coating.
