An instrument specifically made to capture images in the ultraviolet region of the electromagnetic spectrum is known as a UV camera.
Our eyes cannot see this portion of the electromagnetic spectrum, thus any renderings of acquired photos must be digitally altered to create colors that our eyes can perceive.
Such specialized photography is typically employed for a variety of academic, therapeutic, or creative goals. Additionally, UV photography can show damage to structures or pieces of art that are not evident to the naked eye.
UV cameras can also be used as diagnostic medical tools to look for things like skin conditions or damage signs.
Some animals in the wild, particularly insects, use UV rays to truly perceive the world. UV cameras can be used to explore the “invisible” marks on many plants used to draw insects for this reason.
At archaeological sites, where it might reveal objects or traffic patterns that would not otherwise be evident, UV photography is also quite helpful.
The method has also been accepted as admissible evidence in court and is frequently utilized in forensic sciences.
A VIS camera sensor is an imager that gathers visible light (400–700 nm), transforms it into an electrical signal, and then arranges that data to create images and video streams.
The same wavelength range that the human eye sees is used by visible cameras, ranging from 400 to 700 nm. By catching light in red, green, and blue (RGB) wavelengths for precise color representation, visible cameras are made to produce images that mimic human vision.
In order to recognize targets and objects in the image, modern security and surveillance cameras perform this at HD resolution or higher and have a number of lens options for wide-angle or telephoto views.
The Global UV-VIS camera market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
The only industrial UV-VIS cameras available from Polytec are sensitive across the whole UV spectrum (UVA, UVB, and UVC), as well as in visible light and near-infrared (IRA or NIR).
For many UV applications, the filter option—which emits wavelengths above 400 nm—is especially intriguing.
It is also possible to produce customer-specific adaptations, such as unique filter pseudo-color software or other adaptations.
The adjustment of UV lasers, the control of UV filters and blockers, the verification of security features on banknotes and ID documents, or even laboratory applications such as in biology/zoology to investigate UV-reflective properties in flora and fauna are typical applications. Short-wave light scatters strongly at surface defects such as scratches.
