Target entity: second-order Fresnel lens Context triple: [Halfway Rock Light, originalLens, second-order Fresnel lens]
-
A.
Fresnel lens
chosen
A Fresnel lens is a compact, lightweight lens design composed of concentric rings that allows lighthouses and other optical systems to project powerful, focused beams of light over long distances.
-
B.
Fresnel
Fresnel is a surname most famously associated with Augustin-Jean Fresnel, the French physicist whose pioneering work on wave optics and the Fresnel lens revolutionized the understanding and application of light.
-
C.
Cassegrain focus
Cassegrain focus is a telescope optical configuration in which light is reflected by a secondary mirror back through a hole in the primary mirror to form a compact, accessible focal point behind the primary.
-
D.
Fresnel zone plates
Fresnel zone plates are diffractive optical elements composed of concentric rings that focus light through interference rather than refraction, serving as lens alternatives in applications like X-ray and microscopy.
-
E.
Barlow lenses
Barlow lenses are optical accessories used in telescopes to effectively increase focal length and magnification by diverging the light path before it reaches the eyepiece.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
Provenance (3 batches)
The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
