Design constraints applied to the design of an achromatic doublet with the SPC method, where SD is the semi-diameter of the lens.

Constraint type	Value
Minimum edge thickness	1 mm
Minimum center thickness	$\frac{SD}{15}$ $Mathematical equation: $$ \frac{\textrm{SD}}{15} $$$
Minimum air gap	1 mm
Effective focal length	100 mm
Minimum curvature	$- \frac{1}{2 \times SD}$ $Mathematical equation: $$ -\frac{1}{2\times \textrm{SD}} $$$
Maximum curvature	$\frac{1}{2 \times SD}$ $Mathematical equation: $$ \frac{1}{2\times \textrm{SD}} $$$
