Objective lenses are the optic components of microscopes that take light from the object being observed, focuses the rays and then produces the image.

Although all four objective types will correct for achromatic errors (color errors), there is no “achromatic” in the name of “semi plan”, “plan”, and “semi-APO”. The difference between the lenses is the focusing area which can be seen from the eyepieces when using the objective lenses. The difference at the low power lenses is smaller than at the higher 40/60/100x lenses.

A plan objective corrects better for color and spherical aberration that either the semi plan or the achromatic objective. Plan objectives have a flat field around the center of close to 100% of the image and gives flatter fields and slightly higher resolving power (details). Plan objectives are supplied to middle and high end laboratories.

Photons incident on the surface of a semiconductor will be either reflected from the top surface, will be absorbed in the material or, failing either of the above two processes, will be transmitted through the material. For photovoltaic devices, reflection and transmission are typically considered loss mechanisms as photons which are not absorbed do not generate power. If the photon is absorbed it has the possibility of exciting an electron from the valence band to the conduction band. A key factor in determining if a photon is absorbed or transmitted is the energy of the photon. Therefore, only if the photon has enough energy will the electron be excited into the conduction band from the valence band. Photons falling onto a semiconductor material can be divided into three groups based on their energy compared to that of the semiconductor band gap:

The absorption of photons creates both a majority and a minority carrier. In many photovoltaic applications, the number of light-generated carriers are of orders of magnitude less than the number of majority carriers already present in the solar cell due to doping. Consequently, the number of majority carriers in an illuminated semiconductor does not alter significantly. However, the opposite is true for the number of minority carriers. The number of photo-generated minority carriers outweighs the number of minority carriers existing in the doped solar cell in the dark (because in doping the minority carrier concentration is so small), and therefore the number of minority carriers in an illuminated solar cell can be approximated by the number of light generated carriers.

These are additional lenses built-in to improve corrections even further, and therefore they give the most superior image. While they give the best image, they also are the most expensive. They are used by high end users where extreme quality of images and details are required.
