Abstract: A bimodal zoom lens includes three coaxially aligned lenses including a first lens, a third lens, and a second lens therebetween. The first lens is a negative lens, each of the second lens and the third lens is a positive lens. The three coaxially aligned lenses form (i) a first configuration when the second lens and the first lens are separated by an axial distance L11 and (ii) a second configuration when the second lens and the first lens are separated by an axial distance L12, which exceeds axial distance L11. The second configuration has a second effective focal length that exceeds a first effective focal length of the first configuration.

Abstract: A lensed beam-splitter prism array includes a beam-splitter substrate with a plurality of planar and parallel thin-film coatings each spanning a top substrate surface and a bottom substrate surface, and making an oblique angle therebetween, and a lens form layer formed on the top surface and having a plurality of lens forms, each lens form being above one of the plurality of coatings. A method for fabricating a lensed beam-splitter prism includes bonding a plurality of substrates to form a substrate stack having a coating between each adjacent substrate pair. The method also includes forming a stack slice by applying a plurality of parallel cuts at an oblique angle with respect to each coating. Each coating spans a first stack-slice surface and a second stack-slice surface opposing the first stack-slice surface. The method also includes forming a lens form layer on the first stack-slice surface spanning one or more coatings.

Abstract: A four-element athermal lens includes four coaxially aligned lenses including a (i) first lens and, in order of increasing distance therefrom and on a same side thereof, (ii) a second lens, a third lens, and a fourth lens. The first lens and the second lens are positive lenses. The third and fourth lenses are negative lenses.

A difference between (i) the maximum of n1, n2, n3, and n4 and (ii) the minimum of n1, n2, n3, and n4 being less than 0.05 in a free-space wavelength range. Refractive indices n1, n2, n3, and n4 have respective temperature dependences Δ n 1 Δ T , Δ n 2 Δ T , Δ n 3 Δ T , Δ n 4 Δ T . Each of Δ n 1 Δ T and Δ n 2 Δ T exceeds, in the free-space wavelength range, each of Δ n 3 Δ T and Δ n 4 Δ T by a factor between 2.05 and 2.85, inclusive.

The plano-concave lens has a second planar surface on a second side of the biplanar substrate opposite the first side, and is formed of a material having a second Abbe number less than the first Abbe number. The first and second lens have respective focal lengths F1 and F2 that may satisfy −1.4
