Optical wavelength range

WebThe exact wavelength(s) or line(s) at which this occurs is determined by the characteristics of the laser medium. For example, CO 2 molecules readily lase at 10.6 µm, while neodymium-based crystals (like YAG or vanadate) produce wavelengths in the range between 1047 and 1064 nm. Each laser wavelength is associated with a linewidth, which ... WebWhat is SWIR? Short-wave infrared (SWIR) light is typically defined as light in the 0.9 – 1.7μm wavelength range, but can also be classified from 0.7 – 2.5μm. Since silicon sensors have an upper limit of approximately 1.0μm, SWIR imaging requires unique optical and electronic components capable of performing in the specific SWIR range.

WebTraditional Coated Optical Filters tend to achieve a maximum transmission near the center wavelength, whereas Hard Coated Optical Filters tend to have a fairly flat transmission profile over the spectral bandwidth. Bandwidth. Bandwidth is a wavelength range used to denote a specific part of the spectrum that passes incident energy through a filter. The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light. A typical human eye will respond to wavelengths from about 380 to about 750 nanometers. In terms of frequency, this … See more In the 13th century, Roger Bacon theorized that rainbows were produced by a similar process to the passage of light through glass or crystal.
