Polyimide optical articles having selective transmittance properties

An article comprising a lens having a width of 0.1 millimeters to 100 millimeters, a length of 0.5 millimeters to 500 millimeters, and a thickness of 0.2 millimeters to 5 millimeters;

• and the lens (i) transmits more than 60% of light having a wavelength of 760 nanometers to 2500 nanometers, wherein the lens comprises a polymer and a colorant component, and the polymer comprises:
• a polyimide comprising structural units derived from
• (A) a dianhydride/diamine pair wherein the pair comprises
• (i) oxydiphthalic anhydride and diaminodiphenylsulfone, or
• (ii) a dianhydride selected from the group consisting of oxydiphthalic anhydride, 3,3, bisphenol A dianhydride, 4,4, bisphenol A dianhydride, and combinations of the foregoing dianhydrides and a diamine selected from the group consisting of meta-phenylenediamine, para-phenylenediamine, diaminodiphenyl sulfone, oxydianiline, and combinations of the foregoing diamines,
• (B) a chloro-substituted phthalic anhydride, a diamine selected from the group of meta-phenylenediamine, para-phenylenediamine, diaminodiphenyl sulfone, oxydianiline and combinations thereof, and a dihydroxy phenol salt, or
• (C) a combination selected from the group of (A) and (B);
• and the colorant component comprises (a) at least two organic dyes, (b) at least an organic dye and an organic pigment, (c) at least two organic pigments,
• or (d) combinations thereof and wherein the lens is transparent and dimensionally stable at a wall thickness of at least 0.2 millimeters to 5.0 millimeters and remains transparent and dimensionally stable after being (a) exposed to a precondition of 60° C./60% relative humidity for 120 hours and (b) then subjected to a lead free solder test having a peak temperature of 260° C. for up to 30 seconds.
