FAQ

What is the Radius of Curvature at Section 1?
Radius of Curvature at Section 1 is the radius of the curvature of the lens at a specific section, which is a critical parameter in lens design and optics. Radius of Curvature at Section 1 is usually measured using the Meter for Length. Note that the value of Radius of Curvature at Section 1 is always positive.
Can the Radius of Curvature at Section 1 be negative?
No, the Radius of Curvature at Section 1, measured in Length cannot be negative.
What unit is used to measure Radius of Curvature at Section 1?
Radius of Curvature at Section 1 is usually measured using the Meter[m] for Length. Millimeter[m], Kilometer[m], Decimeter[m] are the few other units in which Radius of Curvature at Section 1 can be measured.
