| objective circle | <microscopy> When the focused objective is examined by with- drawing the ocular and viewing its back focal plane through the microscope bodytube, the limiting boundary of the objective, the circumference of the white spot of light, is the objective circle. (05 Aug 1998) |
| objective, fluorite | <microscopy> An objective using the mineral fluorite in its construction. It is usually intermediate between achromatic and apochromatic in correction, but may be more highly corrected. See: illumination, eyepiece. (05 Aug 1998) |
| objective optometer | <optics> A contrivance for exhibiting and measuring the refraction of light. Origin: Refraction. Source: Websters Dictionary (01 Mar 1998) |

| objective probability | A probability of an outcome based either on unassailable theory or extensive empirical experience of exactly the same combination of circumstances; the notion also implies that the realization concerned has not been effected and therefore even in principle not known with certainty.
