Lenses for Laser Diode

Aspheric Precision Molded Lenses for LD Lenses designed to converge incident light onto a single point. This is done by correcting spherical aberrations by altering the surface curvature of the lenses according to distance from the optical axis.

Near Infrared LD Collimator Lenses Prism pairs for expanding an LD elliptical collimated beam in the minor-axis direction and correcting it to a beam almost circular in shape.

LD Anamorphic Prisms Pair Lenses for converging or collimating light emitted by LDs.

LD Beam Expanders Usable both for suppressing beam diffusion and for irradiating beams uniformly and coherently over a wider area. (Discontinued)

LD Receiver Lenses Lenses for converging or collimating light emitted by LDs.
