Abstract

The lens is designed for use at 1.06 μm, but it is null tested for aspherizing with visible light, thus facilitating manufacture.

Fig. 1
Fig. 1

An F/1 aspheric singlet lens; after null figuring in the visible the curvature of the second surface is changed slightly to correct it in the ir.

Fig. 2
Fig. 2

An F/1 aspheric singlet with an auxiliary zero power system for null correcting in the visible light. The aspherizing with respect to the best fit sphere is about 0.7 mm.

Fig. 3
Fig. 3

An F/1 aspheric doublet. The aspheric component is null figured in the visible without the meniscus; on adding the meniscus ir correction is obtained.

Fig. 4
Fig. 4

An F/1 aspheric doublet. The aspheric surface is null figured in the visible with a set air space of 8.6 mm. On reducing the space to about 7.345 mm the system is correct in the ir (λ 1.064 μm) for vacuum. A polynomial representation of the aspheric surface with coordinates in millimeters is: x = Σ n = 0 A n y 2 n + 2 , A 4 = 0.206571 × 10 17 , A 0 = + 0.385505 × 10 2 , A 5 = + 0.130762 × 10 20 , A 1 = 0.370286 × 10 7 , A 6 = 0.477705 × 10 24 , A 2 = 0.343066 × 10 11 , A 7 = + 0.932610 × 10 25 , A 3 = + 0.189494 × 10 14 , A 8 = 0.752406 × 10 32 ,
