Paul’s prism, also known as the Promo prism, is a refraction prism used in optical instruments to modify the orientation of the image. Light enters from the largest rectangular plane of the prism, passes through two full reflections of the inclined plane, and then emits through the original plane of incidence. Because light just enters and exits normally, the prism does not have the effect of dispersion. But the image through the Paul prism will be flipped 180 degrees and will travel in the original direction of entry, that is, the direction of travel will also be changed 180 degrees. But because the image is reflected twice, the handedness doesn’t change.

The pentagon prism is one of the 90° (fixed Angle) beam steering devices. It serves two purposes. One is that the outgoing light redirects the incoming light at an Angle (90°), regardless of the incidence Angle on the first side. The second is that, unlike a rectangular prism, the resulting image is neither rotated nor specular. Pentaprisms are commonly used in camera viewfinders, image-viewing systems, or measuring instruments.

Rectangular prisms are usually used to turn optical paths or to deflect images created by optical systems by 90°. Depending on the orientation of the prism, the image can be left and right and upside down and right and left and right. Rectangular prisms can also be used for image combination, beam migration, and other applications.

A triangular prism is an optically transparent body with a triangular cross-section. It is an optical instrument with a triangular cross-section made of transparent materials. It is a kind of dispersion prism, which can make the complex light disperse when passing through the prism.

Since the same medium has a different refractive index to various monochromatic lights, the deflection Angle of each monochromatic light will be different according to the law of refraction. Therefore, white light through the prism will separate each single color light, forming red, orange, yellow, green, blue, indigo, and purple seven colors, namely dispersion.

Because of their small size and their ability to align the objective and eyepiece, ridge prisms are often used in extremely compact binoculars. Under the condition that the direction of the optical axis and the imaging direction in the main section is not changed, one reflection is added to make the total number of reflections of the system change from odd to even, so as to achieve the requirement of the similarity of the object image.

Optical thin films are widely used in everyday optical systems, industrial products, and consumer electronics. ... read more

Two mutually perpendicular reflecting surfaces are called ridge surfaces, and a prism with ridge surfaces is called a ridge prism.

The polarization splitter prism can polarize the incident unpolarized light into two vertical beams. Where the P-polarized light passes through completely, while the S-polarized light is reflected at a 45-degree Angle, and the exit direction is 90 degrees with the Plight. The polarization-splitting prism is composed of a pair of high-precision right Angle prisms, one of which is coated with a polarization-splitting medium film on the hypotenuse.

Prism: A transparent object surrounded by two intersecting but not parallel planes, used to split or disperse light beams. A prism is a polyhedron made of transparent materials such as glass and crystal. It is widely used in optical instruments and is an important optical element. Next, let’s learn the classification of optical prisms.

The Dowell prism is a kind of spinner. When light passes through this prism, the image is reversed 180 degrees. In addition, when the prism is rotated on its optical axis, the rotation Angle of the image is twice the rotation Angle of the prism. Generally speaking, the Dawei prism uses the critical Angle principle to achieve internal total reflection, so its field of view is limited. At the same time, it is important to keep the reflective surface clean and use parallel light.

When two mirrors are formed at a right Angle, a roof surface is formed. The most commonly used prism principle of Beehan requires six reflections. There is a corresponding abbe prism commonly used in modern Zeiss telescopes, also a roof prism, slightly longer, but only four reflections, and does not require reflective coating, so the efficiency is higher than the Beehan prism and about the same as the ordinary Paul prism.

Paul prisms are most commonly used in pairs as a combination of two Paul prisms, with the second prism, rotated 90° relative to the first. The net effect of the prism system is that the direction of the incoming light is changed parallel, the image is rotated 180°, and the handedness remains unchanged.

The key to ridge prism is the existence of the ridge surface. The so-called ridge surface is a ridge-shaped reflecting surface sandwiched by two reflecting surfaces in the optical path. The edges of the two surfaces are in the middle of the optical path, so some ridge prisms can see that there is a dividing line in the middle.

The maximum dispersion and minimum reflection loss can be achieved when the top Angle is 60°. The higher the dispersion ability or the smaller the Abbe number, the greater the role dispersion.

An equilateral dispersion prism divides a beam of light into different colors and is used in spectroscopic experiments and instruments. When a beam of light strikes the first side at an oblique Angle, because the refractive index of the glass is related to the wavelength, the different colors of the light are refracted at different angles, so that a spectrum appears on the other side.

When rectangular prisms are used, some optical films are usually plated. Rectangular prisms themselves have a large contact area and typical angles such as 45° and 90°, so compared with ordinary mirrors, rectangular prisms are easier to install and have better stability and strength against mechanical stress. They are the best choice of optical components for all kinds of devices and instruments.
