Numerical aperture (NA) is an important specification to define for a microscope objective because it describes the objective’s ability to gather light at a fixed working distance. The NA is often assumed to describe an objective’s resolving power; however, this is not an accurate assumption. The equation below is the first-order equation used to calculate NA. This equation is useful for understanding NA on-axis, but it does not consider field changes for off-axis performance. In addition, this equation does not consider tolerances during the manufacturing and assembly of microscope objectives that can impact the performance.

Figure 1 below demonstrates the off-axis performance of the 5X 120i Plan APO 无限远校正物镜 compared to another 5X Plan APO 无限远校正物镜 from another manufacturer that has the same NA of 0.14. Performance off-axis is better with the 120i Objective in the corner of a 1.1” sensor, indicating that NA is not the defining factor for the performance of an objective.
