These types of devices are typically used in various fields, such as marine biology, environmental monitoring, and educational purposes, to study aquatic life, habitats, and water conditions.

Applied optics is a field of study that focuses on the practical applications of optical principles and technologies. It merges theoretical optics with engineering and technology to solve real-world problems involving light. This can include the design, development, and optimization of optical systems and devices for various applications across multiple industries. Key areas within applied optics include: 1. **Imaging Systems**: Designing cameras, microscopes, and other imaging devices that utilize lenses, sensors, and other optical components to capture and analyze images.

The Celor lens is a type of optical lens that is often associated with camera systems and photography, particularly in the context of film photography. It is known for its ability to produce images with certain optical characteristics, such as sharpness and contrast. The term "Celor" can also refer to specific models of lenses used in vintage cameras or in particular photographic applications. However, without specific context, it is difficult to provide detailed information.

Cross-phase modulation (XPM) is a nonlinear optical phenomenon that occurs in optical fibers and other nonlinear media. It arises when two or more optical signals (or channels) co-propagate through a nonlinear medium, such as a fiber optic cable. The intensity of one signal can affect the phase of another signal due to the nonlinear dependence of the refractive index on the intensity of the light.

A **crystal monochromator** is an optical device used to select specific wavelengths (or energies) of X-rays, gamma rays, or other forms of electromagnetic radiation from a broader spectrum of wavelengths produced by a source. It relies on the principle of diffraction, where incoming radiation interacts with the regular crystal lattice structure of a crystalline material.

BELLA (Big Electron Laser for Laboratory Astrophysics) is a high-intensity laser facility developed to explore various aspects of plasma physics, astrophysics, and fundamental physics. The laser was designed to achieve ultra-powerful and ultra-fast laser pulses for advanced research in these fields. Specifically, BELLA aims to create conditions relevant to extreme astrophysical phenomena in a laboratory setting, allowing scientists to study the behavior of matter under extreme conditions.

The B integral, or the B-Integral, often refers to a specific type of mathematical integral used in various fields, but it is most commonly associated with the B-Integral in the context of mathematics and physics.

A Contact Image Sensor (CIS) is a type of imaging sensor used in devices such as scanners and cameras to capture images. Unlike traditional charge-coupled devices (CCDs) or complementary metal-oxide-semiconductor (CMOS) sensors that capture images through a lens, a CIS uses a linear array of optical sensors arranged in a linear format.

A fiber-optic adapter, often referred to as a fiber-optic coupler, is a device used to connect two fiber optic cables together. Its primary function is to align and connect the fiber strands of different cables to ensure a proper optical connection that allows light signals to pass through efficiently. Key features of fiber-optic adapters include: 1. **Design**: They typically have a modular design with ports for both incoming and outgoing fiber optic cables, allowing for easy integration into existing fiber networks.

CAVEman is a term that typically refers to a type of immersive virtual reality (VR) environment designed for scientific visualization and interactive simulations. The term is derived from the "CAVE" (Cave Automatic Virtual Environment) systems, which are immersive display systems that project computer-generated images onto the walls, floor, and sometimes ceiling of a room-sized space.

Calligraphic projection, often referred to as "cavalier projection," is a graphical technique used in technical drawing and computer graphics to represent three-dimensional objects in two dimensions. This type of projection maintains the scale of one axis, typically the depth axis, while the other two axes (usually horizontal and vertical) are represented at an angle, typically 45 degrees to the plane of projection.

A catadioptric sensor refers to a type of imaging sensor that uses a combination of lenses (dioptric) and mirrors (catoptric) to capture images. The term "catadioptric" itself typically describes optical systems that use both refraction (bending of light through lenses) and reflection (bouncing of light off mirrors) to form images.

The **centre wavelength** refers to the specific wavelength that is positioned at the midpoint of a spectral range or wavelength band. It is commonly used in various fields, such as optics, telecommunications, and spectroscopy, to define the central value of a range of wavelengths emitted, transmitted, or detected by a device or system.

Cer-Vit is a type of dental ceramic material used in restorative dentistry, particularly for making crowns, bridges, and other dental prosthetics. It is known for its strength, aesthetic qualities, and ability to mimic the natural appearance of teeth. The material is often favored for its biocompatibility, durability, and resistance to wear.

Chinese Optics Letters is a scientific journal that publishes research articles in the field of optics and photonics. It covers a wide range of topics, including but not limited to, optical materials, devices, imaging, laser technology, and photonic applications. The journal aims to provide a platform for researchers to share their findings and advancements in optical science and technology, fostering collaboration and innovation.

Galileo's telescope, which he improved upon in the early 17th century, used a simple design that included an objective lens to gather and focus light. The objective lens in Galileo's telescope is a convex lens, meaning it is thicker in the center than at the edges, which allows it to converge (focus) incoming parallel rays of light to a focal point.

A Gauss lens, often referred to in the context of optics, typically refers to a specific type of lens system that utilizes the principles of Gaussian optics. One of the most common implementations is a combination of two convex lenses (often one converging and one diverging) that create a focused beam of light with minimal aberrations.
