Lenses

Optosigma Lenses provide precision focusing and collimating for laser beams, imaging systems, and optical instruments. The catalog spans from simple singlet lenses to achromatic doublets that correct chromatic aberration, and aspheric lenses that eliminate spherical aberration for demanding laser and imaging applications.

Lens types from Optosigma:
– Plano-convex (PCX): focusing or collimating; minimal spherical aberration when oriented correctly; standard for laser beam shaping
– Biconvex (DCX): symmetric design; used for object and image at similar distances
– Plano-concave (PCV) and biconcave (DCV): beam expansion and divergence; used with convex lenses to adjust focal length
– Achromatic doublets: two-element cemented lens correcting chromatic aberration; used in broadband imaging and illumination
– Aspheric lenses: single-element lenses with non-spherical surface profile; near-diffraction-limited performance; used for high-power laser focusing and fiber coupling
– Cylindrical lenses: one-dimensional focusing; used for line generation and beam shaping in laser diode collimation

Substrate options include BK7 borosilicate glass (standard, visible), UV-grade fused silica (UV through NIR, low absorption), and N-BK7/N-SF11 for specialized designs.
