High-Performance S-LAH55VS Plano-Concave Lens – 90mm Diameter, 3mm CT, Uncoated with Blackened Edge for Enhanced Optical Performance

Typical application scenarios:

Laser beam expansion: Combined with a convex lens, it increases the diameter of the laser beam and reduces the divergence angle (Kepler or Galileo beam expansion system).

Aberration compensation: Used in microscopes and projection lenses to counteract the spherical aberration and field curvature of the positive lens.

Optical path folding and delay line: Adjusts the divergence angle of the light beam in optical fibers or free-space optical paths to fit the aperture of the detector.

Beam homogenization and illumination: Expands the illumination field of view in projection systems.
