Can a local optician or lab provide measurements (index and radius) of lenses

  1. This is a little off topic, but not very.

    I am experimenting with some lenses for photographic purposes. I
    ordered the shapes (DCX and PCV) in focal lengths I need to accomplish
    overall what I need.

    They are basically scientific surplus. Supplier can provide f.l. and
    diameter only.

    I am wondering if a 1-hour lab or someone else in the industry can
    give me better details like radius of curvature of each surface and
    maybe index of refraction (type of glass). They're often BK7, but it
    would be nice to get decent approximations so I can put them into a
    'light' version of some optics software (OSLO LT).

    Otherwise it's just experimental.

    Thanks for humoring me.

  2. most opticians have a spherometer (lens curve measuring tool) you
    could use to get the radius.
