What applications would these be used in?

Don't be fooLED, T8 IS the worst thing to do to a magnetic T12 fixture.

Fluorescent05, these are used in optical applications where very sharp shadows must be cast...in fact you can see all the (shadows of the) imperfections and dirt on the bulb crown because the luminous spot is so small.

The specific types of applications would be things like the design and testing of camera lenses, transfer of images from one surface to another, allignment of optical systems etc.

Interesting that it does nit have a piece of optically flat glass glued on top with Indium, but tha rather "knarly" and imperfect hemispherical bulb crown.

Manufactured articles should be made to be used, not made to be sold!
