http://labrigger.com/blog/2010/06/29/high-na-low-mag/ WebThe NA is calculated from the refractive index in front of the objective and the half-angle (θ) of light that the lens transmits from the sample towards the detector.. NA = n * sinθ The more open the aperture, the more angles of light that can pass through the lens to the sample, and the higher the NA.At its largest, the angle would be defined by the radius and …
WebNov 12, 2024 · In this design, a high-NA primary objective (100X, NA 1.35) with an angular aperture of ~74 degrees is matched to a secondary air objective (40X, NA 0.95) with a … WebAn objective’s NA is a measure of its ability to gather light. It is an important factor in determining the resolution, depth of focus, and the brightness of images. Objectives with a larger NA gather a wider range of light, resulting in brighter, higher resolution images.
