The Quality Thin Films (QTF) PLCX-38.1-257.5-SS3001 is a high-precision plano-convex laser lens designed for near-infrared applications around 1030 nm. The lens features a 38.1 mm (1.5″) diameter and a 257.5 mm focal length, making it well suited for beam shaping, collimation, and focusing in ultrafast and solid-state laser systems.
Both optical surfaces (S1 & S2) are coated with a high-performance anti-reflection coating providing ≤0.1% reflectance at 1030 nm, minimizing Fresnel losses and maximizing transmission. Manufactured by Quality Thin Films, this lens meets stringent optical quality standards for scientific and industrial laser applications.
Typical Applications:
-
Yb:YAG and Yb-fiber laser systems (1030 nm)
-
Ultrafast and femtosecond lasers
-
Beam expansion and focusing optics
-
Research, laboratory, and OEM laser integration
