Abstract

Generating reference on the back focal plane (BFP) of objective lens has been an excellent solution for numerical aperture (NA) measurement. Although the effectiveness of the concept of BFP reference has been verified theoretically and experimentally, there has been no practical apertometer based on this concept. The main challenge is how to realize the assembly of the system. In this work, we present the instrument assembly of the apertometer based on BFP reference, which mainly has three requirements. After that, we specifically investigate the influence of the location of the coverslip on BFP image and NA value by using ZEMAX. This work promotes the instrumentation of BFP-typed apertometer significantly.
