Optical window wavelength
The near-infrared (NIR) window (also known as optical window or therapeutic window) defines the range of wavelengths from 650 to 1350 nanometre (nm) where light has its maximum depth of penetration in tissue. Within the NIR window, scattering is the most dominant light-tissue interaction, and therefore the propagating light becomes diffused rapidly. Since scattering increases the distance travelled by photons within tissue, the probability of photon absorption als… WebApr 7, 2024 · Wavelength Division Multiplexing (WDM) is a technology that allows multiple signals to be transmitted over a single fiber optic cable by using different wavelengths (colors) of light.

WebOptical windows for use with lasers require durable coatings (dielectric coatings) designed for use at specific wavelengths. When choosing an anti-reflective coating it is important to specify the percentage of reflectivity you require at a specific wavelength(s) as well as the AOI (angle of incidence) you will be using the optical window. WebApr 12, 2024 · Single-mode used in long distance system buildings, single-mode fiber optic cable with emission wavelength 1310nm or 1550nm FP or DFB laser, means that most of the fiber optic cable is only open a window.
