- Numerical aperture 6/10/2024 Definition: Abbreviation: NA The sine of the maximum angle of incidence for some optical devices, or the sine of the acceptance angle for a waveguide or fiber. Numerical aperture (NA) has two different meanings, one for fiber optics and one for imaging fibers. Numerical aperture of a fiber or waveguide In a ray diagram, a beam can be viewed as propagating in air and incident on the core of...
- Focal length 6/2/2024 Definition: A measure of how well an optical system focuses or defocuses light. Many types of optical systems (e.g., microscope objectives and curved laser mirrors) can focus or defocus light, and focal length is a quantity that quantifies these effects. The simplest case is a thin lens (Figure 1a). If the light entering the lens is a collimated beam, the beam will be focused after passing th...
- Polarization of laser emission 5/26/2024 Definition: Definition: The direction of electric field vibration of the laser beam. In most cases, the emitted light from a laser is polarized. Usually linearly polarized, that is, the electric field oscillates in a specific direction perpendicular to the propagation direction of the laser beam. . Some lasers (for example, fiber lasers) do not produce linearly polarized light, but other stable...
- Return loss 5/20/2024 Definition: A measure of how much reflected light is attenuated. Return loss (or reflection loss) of an optical device (or combination of devices) represents the degree to which the returned optical power is reduced compared to the light incident on the device. Typically, return loss is characterized in decibels. For example, if the return loss is 30dB, then the returned light is 1/1000 of the...
- Infrared light 5/12/2024 Definition: Invisible light with wavelengths between 750nm and 1mm. The wavelength of infrared light is greater than 700-800nm, which is the upper limit of the wavelength of visible light. The boundary between the two is not very clear, and the responsivity of the eye decreases very slowly in this area. Although the responsivity is already very low at 700nm, it can still be seen at a wavelengt...
