Photography microscope is a compound microscope connected to a digital camera used to capture photomicrographs. Photomicrograph is a photograph taken through a microscope.

A compound microscope is an optical system wherein a true magnified image is produced by one lens (or lens system) called objective and is again further magnified by what is called eyepiece in which, finally becomes the magnified, final virtual image for observation. Brightfield, darkfield, and phase contrast are several illumination techniques a microscopist can use.

A compound microscope has a few components. They are the objectives (dry and immersion objectives), the ocular (eyepiece), and the condenser. Moreover, it also consists of special optical components, such as the phase centering telescope and the projection eyepiece (photo eyepiece). In addition, to complete the optical setup of a compound microscope: filters prisms and a so-called tube lens are also important parts to be included.

A compound microscope is a precision instrument made of different mechanical and optical parts. The output and performance of a good scope is dependent on the quality of mechanical parts and lenses used.

When a compound microscope generates light through its lamp filament, which illuminates through the transmission of light, first it passes through the collector’s lenses, filters and through the condenser, microscope slide, specimen, cover glass, objective, and ocular. Lastly, it goes to the observer’s eye(s).

Objective Objective is one of the most important parts of a microscope. If it does not perform well, the microscope cannot offer the most expected output. “Low power” objectives” are the first set of objectives. Its magnification ability ranges from 2x to 25x.

The next set of objectives is called the “high power” objectives. Their magnification ability ranges from 25x and 100x. Some microscopes can have as much as 200x magnification power. These lenses are mostly expensive and not trivial to use due to the small distance between the front lens of the objective and the specimen. This objective mostly comes with spring-loaded front lenses, which automatically withdraws if the objective accidentally touches the specimen or cover glass. There is a special type of high power objective called immersion lens. This special lens can be immersed through water or oil.

The ocular or eyepiece The ocular of eyepiece is the closest group of lenses to an observer’s eye. The primary goal of the ocular is to provide a virtual image. There are various types of oculars available. The magnification ability of these oculars ranges from 5x to 25x. The most commonly used is the 10x.

Special kinds of oculars Phase centering telescope. This ocular consists of a movable lens that allows the microscopist to focus on the back focal plane of the objective. This is necessary when centering Köhler illumination or centering the phase rings used for phase contrast microscopy. Next is the”projection eyepiece”. This ocular is used to capture a real image that can be projected onto a film emulsion or digital recording tool
