The biconvex lens is made of two identical spheres. Since the radius of the two spheres is equal, the aberration, aberration and chromatic aberration are effectively eliminated. They are combined with other lenses to form an imaging system.
Basic Technical Parameters
Tolerance of Dimension: ±0.05mm
Surface Accuracy: 1/2λ，λ/4 per φ25.4mm
Centration：≥1′
Surface Quality: 60-40, 40-20, 20-10，10-5
Chamfer: 0.2-0.3mm×45°
Clear Aperture： >90%
Polish： High-precision Polish on Both Surfaces
Biconvex lenses are ideal for many limited imaging applications, because the front and rear surfaces of the double convex mirror are convex spheres and the curvature radii are equal, the lens has symmetry, the spherical difference can be minimized, and the aberration and distortion are eliminated.
