-
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.
Wollaston prism
A Wollaston prism is an optical device made of two birefringent crystal wedges cemented together to split a beam of light into two orthogonally polarized rays.
-
D.
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.
-
E.
Cassegrain telescope
A Cassegrain telescope is a reflecting telescope design that uses a combination of a primary concave mirror and a secondary convex mirror to fold the optical path and produce a compact instrument with a long effective focal length.
