BICONVEX AND ASYMMETRIC LENSES BCX - ABL
Description
Biconvex lenses (BCX) and asymmetric lenses (ABL), similar to PCX ones, have positive focal lengths combined with convex surfaces. The surfaces of BCX lenses have equal and symmetrical radius of curvature, while ABL ones have both convex surfaces but with different radius of curvature. In the latter case there is a special relationship between the two surfaces, called form factor, which identifies the best shape that an asymmetric lens can have as a function of the distances between the lens and its conjugate points.

Frequently Asked Questions
BCX and ABL lenses are lenses with positive focal lengths combined with convex surfaces. BCX lenses have equal and symmetrical radius of curvature, while ABL lenses have both convex surfaces but with different radius of curvature.
The special relationship between the two surfaces of ABL lenses is called form factor, which identifies the best shape that an asymmetric lens can have as a function of the distances between the lens and its conjugate points.
BCX and ABL lenses can be used in laser optics, metrology, spectrometry, OEM, and industrial applications.
BCX lenses can cancel some aberrations such as distortion, lateral chromatic aberration, and coma, while ensuring low residuals of spherical aberration.
Tecnottica Consonni makes available the realization of BCX and ABL lenses in different optical glasses with several Anti-Reflection coating optimized for ultraviolet (UV), visible (VIS), near infrared (NIR and SWIR) and other bands of your choice.
