HIGH-OUTPUT LENS
FIELD: physics.SUBSTANCE: high-aperture lens consists of four components, of which the first is a single convex-plane lens, the second is a single positive meniscus whose convex surface faces the object space, third is a single biconcave lens with a radius of the first optical surface along the beam...

| Zusammenfassung: | FIELD: physics.SUBSTANCE: high-aperture lens consists of four components, of which the first is a single convex-plane lens, the second is a single positive meniscus whose convex surface faces the object space, third is a single biconcave lens with a radius of the first optical surface along the beam path modulus greater than the radius of the second optical surface, and the fourth is a glued positive lens consisting of a biconvex lens and a negative meniscus in the direction of the beams and facing the object with its concave side. Ratio is as follows: 0.0024 ≤ d/f' |
