✅ Applications & Performance
-
Optimized for 1064 nm lasers (e.g. Nd:YAG), makes it well-suited for beam focusing, imaging, or coupling into small apertures.
-
High NA of 0.142 yields compact beam waist (low focal ratio around f/3.15), suitable for tight focusing.
-
Diffraction-limited performance across a broad spectrum ensures excellent image quality and minimal aberrations even at off-design wavelengths.
