Focus-Ronar Lenses 1064 and 532 nm
Focusing lenses are optimized for high-precision applications in laser systems used for welding, cutting, drilling, and structuring.
LINOS Focus Ronar lenses are available in fused silica (355 nm) and optical glass (532 nm, 1064 nm), covering focal lengths from 58 to 122 mm. A precision three-element lens design enables flexible lens exchange without the need for adjustment.
