Low light level television
electronic light sensing device sensitive to wavelengths into the near infrared
Low light level television (LLLTV) is a type of electronic sensing device, usually a CCD camera sensitive to wavelengths above the normal "visible" (0.4 to 0.7 micrometre) wavelengths, and into the short-wavelength infrared (SWIR) - usually to about 1.0 to 1.1 micrometres. This allows viewing of objects in extremely low light levels, where they would not be seen by the naked eye. LLLTVs tend to be more affordable than infrared cameras, which typically cover ranges from 3 to 5 μm (mid-wavelength infrared or MWIR) or 8 to 12 μm (long-wavelength infrared or LWIR).
The public source identifies “Low light level television” as electronic light sensing device sensitive to wavelengths into the near infrared. This brief keeps that definition visible, then builds a research path around light, level and television.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Low light level television”, the useful work is to connect “electronic light sensing device sensitive to wavelengths into the near infrared” to the records capable of establishing context and consequence.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 1, 2026. The linked authority identifier is Q5645970. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
