Product: The Effects of Coolant on Fixed Diamond Lapping Pads When Processing Hard Optics
Top Line: Universal Photonics Incorporated (UPI), global manufacturer and distributor of critical surfacing and polishing technology, announced its participation in the 2023 Photonics Spectra Online Conference, January 9 - 12. UPI’s webinar, presented by Christopher Russell, senior field application engineer, will discuss the effects of coolant on fixed diamond lapping pads when processing hard optics. The webinar will go live on Tuesday, January 10, 2023, at 3:00 PM EST. Registration, available at, is free, but required.
Close Up: The 3rd annual Photonics Spectra Conference is a four-day online event showcasing four technology tracks, allocating one day to each of the following tracks: Lasers, Optics, Test & Measurement, and Photonic Integrated Circuits. The program features 60 industry-leading speakers presenting on a wide range of topics, including the latest developments in materials processing, spaceborne optical platforms, freeform optics, beam profiling, optical metrology, lasers for quantum computing, and the fast-expanding applications driving demand for PIC technology.
Vital Stats: Christopher Russell has been a team member of UPI since the mid-aughts. A Clarkson University alumnus, Russell came on board as an engineer in UPI’s quality control lab. His expertise and time spent in the industry allows him to provide helpful insight on hard optics processing. Discussing the effects of coolant on fixed diamond lapping pads throughout the process, Russell identifies critical parameters (e.g. coolant type, working pressure, conditioning particle, and platen speeds) to successfully achieve specific desired results. A live Q&A is built into the presentation, so he can address questions, comments or concerns. Additionally, Russell can be reached via email, at
