LCDs contain a lighting system that’s responsible for illuminating their pixels. Some of them use light-emitting diode (LED), whereas others use electroluminescent (EL). Regardless, all LCDs have a lighting system. A polarizer is a layer of light-filtering material that’s placed between the backlighting and the LCD’s pixel layer.

In the previous calculation, I assumed an angle of acceptance of 72-degrees with a reasonable upper limit when working with air (that angle gives us a NA of 0.95). However, by immersing the sample and microscope in oil or another liquid, it is possible to have a larger NA. This affects not only the resolution of our image but also its brightness (the brightness is calculated as the square of its NA).

Polarizers work on the principle of polarization. The pixels in an LCD must project a specific level of brightness to create a visible image. The problem is that most LCDs are comprised of millions of pixels. And to create an image, many of these pixels require varying levels of brightness. Some of the LCD’s pixels, for example, may need to be brighter than others. With polarizers, LCDs can control the brightness of their pixels, resulting in the production of high-quality and visible images.

Objective lenses can have just a couple of lens elements, (an achromat and simple lens, for example) or multiple groups of elements. Even two microscope objectives with the same magnification can have a completely different design, as shown in Figure 1.

In cases where the objective is not meant to be used in infinity corrected microscopes, there will be a number, usually 160) referring to the length of the microscope tube. Some microscope objectives will show the letters “DIN” which stands for “Deutsche Industrial Normen.” that sets a length of 160 mm.

Objective lenses for microscopes typically have several components, including the front lens, the rear lens, the aperture, the lens barrel, and the thread. Each component plays an important role in determining the objective’s performance. For example, the aperture determines the resolution and depth of field of the objective lens, while the thread allows the objective to be attached to the microscope.

Polarizers work by restricting the type of light that reaches the LCD’s pixel layer. The purpose of a polarizer is to create visible images. Without them, you wouldn’t be able to see the images produced by an LCD.

The simplest designs are usually called ‘achromat objectives’ and contain only a front lens and a couple of achromatic doublets to correct for aberrations. On the other hand, we have Apochromat microscope objectives in which several apochromatic doublets are used, in addition to some achromats for a better image quality. For a better explanation of the difference between achromatic and apochromatic lenses, please read the linked articles.

LCDs typically have two polarizers. Polarizers are typically made of a clear crystalline material. They are designed specifically to allow certain wavelengths of light while blocking others. The light produced by the LCD’s lighting system must pass through the polarizers before reaching the pixel layer.

Microscope objective lenses are a crucial part of a microscope, responsible for magnifying the specimen being observed. They are used to gather light from the object being observed and focus the light rays to produce a real image. The objective lens is one of the most important parts of a microscope, as it determines the microscope’s basic performance and function [3].

Another specification can be “Plan Fluor” for fluorite and “APO” for apochromatic. Next we have the magnification, numerical aperture, and the immersion medium. As mentioned before, dry objective lenses usually have a NA no larger than 0.95, but that number can be considerably higher in immerse objectives. We next have an infinity symbol, meaning that the lens is infinity corrected.
