An Amici roof prism is an optical component used in binoculars, telescopes, and other optical devices to invert and revert an image, which allows for a more compact design. The Amici prism system differs from other roof prism designs, such as Schmidt-Pechan prisms, in that it uses a different optical arrangement.
Becke line test by Wikipedia Bot 0
The Becke line test is a method used in microscopy and forensic science to determine the refractive index of small particles, particularly in the context of assessing the identity of mineral samples or glass fragments. This test is especially valuable in forensic investigations, such as analyzing evidence from crime scenes.
Binoviewer by Wikipedia Bot 0
A Binoviewer is an optical device used in telescopes and astronomical binoculars to provide binocular vision by allowing both eyes to view the same image simultaneously. This device splits the incoming light from the telescope into two beams, allowing for a more immersive and comfortable viewing experience compared to observing with one eye. Binoviewers are particularly popular among amateur astronomers for observing celestial objects, as they can enhance depth perception, make the experience more natural, and reduce eye strain during long observing sessions.
Caesium cadmium chloride is a chemical compound composed of cesium (Cs), cadmium (Cd), and chlorine (Cl) atoms. It is often represented by the formula Cs2CdCl4, which indicates that two cesium ions and one cadmium ion are combined with four chloride ions. This compound belongs to a class of materials known as halides and can exhibit interesting properties that are useful in various applications, such as in the fields of photonics and materials science.
Campimeter by Wikipedia Bot 0
A campimeter is a device used in ophthalmology to measure the visual field of the eye. It is designed to assess peripheral vision and can help detect visual field defects caused by various conditions like glaucoma, retinal diseases, and neurological disorders. The test typically involves an individual looking straight ahead while a series of lights or stimuli are presented in different areas of their peripheral vision. The responses to these stimuli are recorded to create a visual field map, which helps in diagnosing and monitoring eye conditions.
A Coherent Perfect Absorber (CPA) is a device or system that is designed to absorb incoming electromagnetic waves (such as light) completely, without reflecting or scattering any of that energy. It achieves this by using interference effects, where the incoming waves are perfectly matched in phase and amplitude to the waves that are coherently emitted by the absorber. The concept of a CPA is analogous to that of a laser, where energy is emitted coherently.
Corona poling by Wikipedia Bot 0
Corona poling is a technique used in the field of polymer science and materials engineering to align the dipoles of certain materials, particularly ferroelectric and piezoelectric polymers. This process is typically performed in the presence of a high electric field and is often conducted in an environment where a corona discharge is generated.
Erect image by Wikipedia Bot 0
An erect image is an image that appears upright, meaning that it maintains the same orientation as the object being observed. In optics, when light rays converge to form an image, the orientation of that image can be classified as either erect or inverted. Erect images are typically produced by certain optical devices, such as: 1. **Convex mirrors**: They produce erect virtual images that are smaller than the object.
SCMITR by Wikipedia Bot 0
As of my last update in October 2023, there is no widely recognized organization or concept known as "SCMITR." It’s possible that it could refer to an acronym, a specialized term, or a new entity that emerged after that date.
Dispersion-shifted fiber (DSF) is a type of optical fiber designed to minimize chromatic dispersion across certain wavelengths, particularly in the wavelength range commonly used for long-distance fiber optic communication, such as around 1550 nm. In conventional single-mode fibers, chromatic dispersion—a phenomenon where different wavelengths of light travel at different speeds—can lead to signal broadening over long distances, which ultimately limits the bandwidth and performance of fiber optic systems.
In optical mineralogy, "extinction" refers to the phenomenon observed when a polarized light beam interacts with a mineral grain in a thin section under a microscope. It describes the behavior of light as it passes through a mineral when it is aligned in certain orientations relative to the polarizers. When observing a mineral under crossed polarizers, extinction occurs when the mineral is oriented in such a way that no light is transmitted through the mineral.
Optic crystals by Wikipedia Bot 0
Optic crystals, also known as optical crystals, are materials that possess specific optical properties, making them suitable for a variety of applications in optics and photonics. These crystals can manipulate light in various ways, such as through refraction, diffraction, polarization, and nonlinear optical effects. Some of the key characteristics of optic crystals include: 1. **Transparency**: Optic crystals are often transparent to certain wavelengths of light, which is essential for many optical applications.
The Fresnel–Arago laws refer to principles related to the diffraction of light, which were formulated by Augustin-Jean Fresnel and François Arago in the early 19th century. These laws are fundamental to the understanding of wave optics and describe how light behaves when it encounters obstacles or slits.
High-power field by Wikipedia Bot 0
A High-Power Field (HPF) is a term commonly used in microscopy to refer to a specific area viewed through a microscope using a high magnification objective lens, typically 40x or higher. The HPF allows for a detailed examination of the specimen, providing a more magnified view that can reveal finer cellular structures and details compared to lower power fields.
Hydroxyl ion absorption typically refers to the interaction of hydroxyl ions (OH⁻) with a substance, particularly in the context of chemistry and environmental science. Hydroxyl ions are negatively charged ions that play a key role in various processes, including acid-base reactions, environmental chemistry, and biological systems. 1. **Environmental Chemistry**: In environmental contexts, hydroxyl ions can be involved in the absorption of pollutants.
Kinoform by Wikipedia Bot 0
Kinoform is a type of phase plate used in optics to modify the phase of light waves passing through it. The term is derived from the German word "Kino," referring to cinema or motion pictures, and "form," indicating the shape or structure. Kinoforms are typically used in applications like diffractive optics, where they help create specific light patterns or focus light in desired ways.

LBLRTM stands for Line By Line Radiative Transfer Model. It is a sophisticated computational model used in the field of atmospheric sciences and astronomy to simulate the transfer of radiation through the atmosphere. The model calculates how light interacts with gases in the atmosphere, taking into account absorption and emission processes by various molecules. LBLRTM is particularly useful for generating spectra of radiative transfer, which are essential for remote sensing applications, atmospheric studies, and climate modeling.

Pinned article: ourbigbook/introduction-to-the-ourbigbook-project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
