Super Polishing

Now CPG Optics is developing super polishing on the spherical lens with Ra<1A. The lens with Ra<1A is intended for applications involving deep UV light including high-energy lasers such as those emitting at 635nm. CPG Optics completed the production of spherical lenses with Ra<4A last year. However, achieving Ra < 1A is still in the experimental stage worldwide and has not yet transitioned to mass production.

However, as is widely acknowledged, significant strides have been made in the research of visible and infrared light, leading to widespread utilization across numerous industries. Yet, when it comes to deep UV light, identifying a material that performs exceptionally well within this spectrum remains a formidable challenge. CPG Optics has endeavored to enhance results by exploring the use of Fused Silica and MgF2.

Currently, we continue to conduct research in this area. If you have any interest in this endeavor, please don't hesitate to reach out to us.
