2 Element Laser Lens for Green
$9.99
2-Element Laser LensAR-Coated for Green (520–532 nm)
OverviewCompact two-element glass collimating/focusing lens optimized for green diode lasers. Delivers improved beam quality and lower divergence versus single-element designs while retaining higher transmission than typical 3-element optics. Intended for 12 mm diode modules requiring balanced power density and beam cleanliness at moderate working distances.
