High resolution, high collection efficiency in numerical aperture increasing lens microscopy of individual quantum dots. published. august 9, 2005. author(s). Numerical aperture (na) = n • sin(α) in the above equation, ‘n’ is the refractive index of the medium between the cover glass and the front lens of the objective (for example; air, water or oil). the ‘α’ symbol relates to half of the angle of the cone of light which can be collected by the lens (i.e., the angular aperture; s. figure 2).

Objective aperture from the sample plane. the larger the numerical aperture, the more light can be collected from a point source radiating in all directions (e.g. from a fluorescent sample). to calculate amount of isotropically generated light collected by a lens of given numerical aperture: numerical aperture = na = sin (θ 2). We demonstrate the application of a subsurface solid immersion technique to the photoluminescence spectroscopy of individual quantum dots. contrasted with the conventional solid immersion microscopy, we used a numerical aperture increasing lens and moved the interface between the sample and the solid immersion lens away from the focal plane, thus diminished the influence of interface artifacts. Select the source and collection optics to: 1. match g lim. the collection optics should have a value of g that is as large as g lim. at smaller values, the collection of light from the source limits the total flux transfer. you can use a higher value of g. more radiation is collected, but this cannot pass through the optical system.
