1. A parallel tailored athermally stabilized optical system (PTASOS) comprising:
(a) optical lens source (OLS);
(b) optical detector target (ODT);
(c) parallel reference surface (PRS);
(d) first retaining tube (FRT); and
(e) second retaining tube (SRT);
wherein:
said OLS comprises a lens reference plane (LRP) perpendicular to an optical axis of said OLS;
said ODT comprises a focal reference plane (FRP) perpendicular to an optical axis of said ODT;
said PRS comprises a parallel reference plane (PRP) parallel to said LRP and FRP;
said FRT comprises a material having a positive first thermal expansion (FTE) coefficient;
said SRT comprises a material having a negative second thermal expansion (STE) coefficient;
said FRT and said SRT are aligned along a common optical axis (COA);
said FRT and said SRT are configured to align said OLS and ODT along said COA;

said TMM, subsequent to said deformation, exhibits a second thermal expansion characteristic in a second direction; and
wherein said TMM comprises a material selected from a group consisting of:
(1) a material characterized by a general formula Ti100-AXA, wherein X is at least one of Ni, Nb, Mo, Ta, Pd, Pt, or combinations thereof, and A is in a range from 0 to 75 atomic percent composition;
(2) a material characterized by a general formula Ti100-A-BNiAXB, wherein X is at least one of Pd, Hf, Zr, Al, Pt, Au, Fe, Co, Cr, Mo, V, O or combinations thereof, and A is in a range from 0 to 55 atomic percent composition, and B is in a range from 0 to 75 atomic percent composition such that A plus B is less than 100;
(3) a material characterized by a general formula Ti100-A-BNbAXB, wherein X is at least one of Al, Sn, Ta, Hf, Zr, Au, Pt, Fe, Co, Cr, Mo, V, O, or combinations thereof, and A is in a range from 0 to 55 atomic percent composition, and B is in a range from 0 to 75 atomic percent composition such that A plus B is less than 100; and
(4) a material characterized by a general formula Ti100-A-BTaAXB, wherein X is at least one of Al, Sn, Nb, Zr, Mo, Au, Pt, Fe, Co, Cr, Hf, V, O, or combinations thereof, and A is in a range from 0 to 55 atomic percent composition, and B is in a range from 0 to 75 atomic percent composition such that A plus B is less than 100.
