transmittance Definition

trans·mit·tance (--mit′'ns)

noun

  1. the act or process of transmitting
  2. the ratio of the radiant energy transmitted by a body to the total radiant energy received by the body

transmittance Usage Examples

Preposition: of

  • %: These standards currently allow visors intended for daytime use only to have a moderate tint with a minimum light transmittance of 50 %.
  • light: Alarms using this kind of sensor use external circuitry to monitor the transmittance of infrared light through the sensor.

Converse of object

  • reduce: Ideally PVC frames should be used in order to reduce thermal transmittance.
  • measure: Examples include measuring the total transmittance and reflectance or by measuring the radial spatial distribution.
  • have: It also has a light transmittance of 92 % ( compared to plate glass with 88 % ), and is suitable for cutting.
  • calculate: You can use the spreadsheets to calculate the transmittance of the new filter combination.

Adjective modifier

  • thermal: Ideally PVC frames should be used in order to reduce thermal transmittance.
  • spectral: Spectral transmittance can be measured at either selected wavelengths or by using a scanning technique at regular intervals.
  • light: Light transmittance of the human cornea from 320 to 700 nm.
  • total: Total transmittance - the ratio of the flux transmitted at all forward angles to the incident flux.
  • high: Consider the following configuration: Figure 1 depicts a circular solar panel with two layers of high transmittance, low emissivity glass.
  • minimum: These standards currently allow visors intended for daytime use only to have a moderate tint with a minimum light transmittance of 50 % .

Modifies a noun

  • value: You should note that negative transmittance values can be used to create very dense fields.
  • channel: The transmittance channel of the atmosphere's color is used to specify a minimum translucency.
  • minima: Polystyrene film has significant thermochromic effects, including shifts in wavenumbers of the transmittance minima.
  • level: For each color, 9 transmittance levels are available, ranging from approximately 3 % to 85 % .
  • measurement: Regular Transmittance NPL is able to make regular transmittance measurements from 200 to 3000 nm.

Noun used with modifier

  • %: Glass will allow over 90 % transmittance of incident solar energy.
  • percentage: A percentage transmittance of 100 would mean that all of that frequency passed straight through the compound without any being absorbed.
  • percent: If all the light is absorbed, then percent transmittance is zero, and absorption is infinite.
