Featuring 65 mm aperture, Models FL1100A-BB-65, FL600A-BB-65, and FL600A-LP1-65 measure laser power from 600 mW to 1,100 W, 600 mW to 600 W, and 1–600 W, respectively. Compact devices operate without water cooling, eliminating necessity of fixed water lines and possibility of contaminated water or corroded sensors. All thermal sensors feature Smart Connector interface that operates with StarLite, Nova II, and Vega smart displays, and Juno PC interface.
