Deviating the prism of the ray path or shifting the image from its original axis, is helpful in many imaging systems.  Light is typically deflected at 45, 60, 90 and 180 degrees.  This helps to aggregate system size or adjust the ray path without affecting the rest of the system settings. The polygonal prism can be set to different angles of deflection according to customer needs.

An important characteristic of a pyramid is that the reflected light is always parallel to the incident light, regardless of the angle of incidence. Corner cubes are used for target determination and quick alignment.

There are four main types of prisms based on the function: dispersion prism, deflection or reflection prism, rotating prism and offset prism.  Deflection, offset and rotating prisms are commonly used in imaging applications; diffusion prisms are designed for dispersive light sources and are not suitable for any application that requires high quality images.

Vectorbord, Veroboard — These are the most common brands of perfboard. Branded perfboard is usually the higher-quality stuff, made more for experimentation than assembling known-working circuits. Cheap perfboard is usually unbranded or it's some kind of “house” brand.

stripboard — This is perfboard with rows of copper strips on it. You cut the strips to form shorter rows of connected holes. This offers a balance between the ultimate flexibility of pad-per-hole board with the convenience of a patterned perfboard.

An interesting feature of a Dove Prism is as it rotates along its longitudinal axis, the emitted image rotates at twice the speed of the prism.  Meaning, it can rotate the beam at any angle, which makes them useful in beam rotators, which are used in areas such as interferometry, astronomy and pattern recognition.

Shanghai Optics can provide high-precision prisms with arbitrary angles, sizes below 300mm and angular accuracy of 1 second.  Customized coatings are available for different UV, visible and infrared wavelengths according to customer requirements.

Right-angle prisms are used as mirrors to deflect light by 90 degrees or as retroreflectors, allowing light to pass through 180 degrees of total internal reflection.  Right-angle prisms can also be used for applications such as stitching and beam shifting.  In addition, using the critical angle characteristic, efficient internal total reflection of incident light is one of the basic functions of a right-angle prism.

Which is the best type? Well, it depends on your needs. Solderless breadboard is convenient, but it's expensive and it's only good for temporary experiments. Also, the concept is flawed by inherent parasitic capacitances and inductances; Bob Pease calls them “white slabs of trouble” because they decrease the chances of success so much, particularly with analog circuits. Plain perfboard is cheap and simple for small projects, but due to the lack of copper patterns the wiring on them often becomes a rats nest of interconnected wires. Pad-per-hole perfboard is a little more mechanically sound, but not much better in terms of neatness. Patterned perfboard can give the neatest layouts if you can find the right pattern and you plan your layout carefully around it, but it's the most expensive type.

The semi-pentagon prisms’ main function is to deflect the light by 45°, and the image is dextrorotatory.  Mainly used in the Pecan mirror assembly.

Literally, a breadboard is a plank of wood intended for cutting bread on. Think early 1900s here, before sliced bread, and before transistors. Even basic projects were large by today's standards. People would take a bread board and use it as a platform to support the tubes, transformers, capacitors and other large components. Bread boards came to be associated with electronics experimenters because they were inexpensive, sturdy and readily available, and it's easy to move components around on them.

The two common types of the Micro-prism are PentaPrism and Right-angle Prism.  These two prisms are widely used in the field of optical fiber communication, especially in the core field of optical switches.  Examples of such applications include circulator interleaver and MEMS.

If you see the term “perfboard” alone, it often refers to just plain perforated circuit boards. You stick the leads of components through the holes and solder the leads to the leads of other components. It's primitive, but it works.

Beware also that there are varying grades of perfboard. The cheapest type has unclad copper pads and the pads are easy to rip off the board if you stress them. This type is okay for soldering down a known-working circuit, but not very good for experimenting. More expensive perfboard types have stronger pads, the pads are often clad with tin so they accept solder more readily, and the board itself is more rugged. You can spend anywhere from a few dollars for a board of several square inches up to about twenty bucks for the same size board, depending on quality. The expensive stuff is only useful if you expect to be modifying the circuit or you need the greatest possible durability.

A prism is a transparent object surrounded by two planes that intersect but are not parallel to each other.  The most important parameters of a prism are the angle and material.  Prisms are widely used in splitting, depolarization, polarization, image orientation, dual channel instruments, etc.

The pentagonal prism has a stable light deviation, which is always 90 degrees regardless of the optical axis and light, and is used for measurement, laser scanning, alignment and other optical tools.

You can also find perfboard types with various copper patterns that connect multiple holes. In the image below, the white markings on the top of the board tell you where copper is on the bottom side. This particular type has a complicated pattern: there are two bus strips down the center of the board, 2-hole pads on the edges of the board, and 3-hole pads and pad-per-holes between the two.

More often, perfboard has a copper pattern printed on its surface, to which you can solder components. The simplest type is pad-per-hole, which simply has a ring of copper around each hole. The advantage of this over plain perfboard is that each component is soldered to the board rather than to each other, so it's easier to work with and the project is more stable.

The other major type of modern experimenter's board is perfboard. At its most basic, perfboard is some type of circuit board material with holes punched in it at regular intervals, usually 0.1".

When the exit surface is incident at a right angle, a 90 degree deflection can occur.  The oblique side is the incident exit surface, and the light is deflected by 180 degrees.

One type of experimenter's board is solderless breadboard, also called plugboard. You just plug components into the holes and they're connected by copper strips underneath.

Dove prism is a reflective prism used to invert an image.It is made up of a truncated right angle prism.A beam of light enters an inclined surface of the prism, undergoing complete internal reflection from the interior of the longest (bottom) surface and exiting from the opposite inclined surface.  The image through the prism is flipped, because only one reflection occurs, so the image is inverted instead of transposed horizontally.
