Example Sentences
- "In an equiconcave lens the foci are virtual and are crossed over; thus, the lens in fig. 25A is equiconcave, the focus F, instead of being measured from A to the right hand, must be measured to the left hand; consequently, § of the thickness must be subtracted from the focal length in order to determine the distance of F from the surface of the lens."
- "In an equiconcave lens, the back surface would have a positive radius of curvature."
- "A thin equiconvex lens of radius of curvature R made of material of refractive index μ₁ is kept coaxially, in contact with an equiconcave lens of the same radius of curvature and refractive index μ₂ (> μ₁)."
