Radiometer
| Fiber Optic Glossary |
- An instrument, distinct from a photometer, to measure power (watts) of electromagnetic radiation.
- An instrument designed to measure the intensity of radiant energy.
- Device used to measure irradiance or radiant energy of specified frequencies. different radiometers exist for different frequencies. in nondestructive testing, radiometers are used to measure uv-a output, or leaked visible light, in microwatt per square centimeter (?w/cm2). see also irradiance. compare photometer.
- Device used to measure irradiance. in nondestructive testing, radiometers are used to measure uv-a output, or leaked visible light, in microwatt per square centimeter (?w·cm–2). see also irradiance. compare photometer.
- Device used to measure irradiance. in nondestructive testing, radiometers are used to measure uv-a output or visible light in si units of watts per square meter (w/m). used in fluorescent penetrant and magnetic particle testing to measure output of excitation sources. see also irradiance. compare photometer.

Instrument, английский
- A term used to describe a sensor (or sensors), the associated transducer(s), and the data read-out or recording device.
- (измерительный) прибор
- One of many terms for a light, heard mostly in the theater. see: lights.
- A piece of equipment or a tool the doctor had a box of surgical instruments.
- A term of extensive application among tools and weapons; but it is here introduced as an official conveyance of some right, or the record of some fact.
- A legal document that records an act or agreement and provides the evidence of that act or agreement. instruments include contracts, notes, and leases (e.g. a debt instrument).

Photometer, английский
- Instrument that measures luminous intensity, luminous flux, light distribution or color.
- An instrument which measures luminous intensity.
- Any instrument that measures photometric quantities such as luminance, luminous intensity, luminous flux, and illumination.
- Device used to measure illuminance. the sensor is filtered such that its response closely matches the spectral responsivity curve of the human eye. in nondestructive testing, photometers measure lux. compare radiometer.
- Device used to measure luminance or illuminance. illuminance photometers are often called lux meters. photometer integral sensors are filtered such that their responsivity closely matches the spectral responsivity curve of the human eye (in other words, the action spectrum of interest). compare radiometer.
Electromagnetic, английский
Irradiance, английский
- The density of the luminous flux which is incident on a surface.
- Интенсивность излучения
- The direct, diffuse, and reflected solar radiation that strikes a surface. usually expressed in kilowatts per square meter. irradiance multiplied by time equals insolation.
- The direct, diffuse, and reflected solar radiation that strikes a surface. usually
- Power of electromagnetic radiant energy incident on or radiated from the surface of a given unit area. compare radiance.
- Radiant power falling upon a known surface area at a given angle. compare radiance. see also radiometer. ishiharatm plates: trade name for a kind of pseudoisochromatic plates, used for color differentiation vision testing.
- Total radiant power, in watts per square meter (w/m2), falling upon a known surface area at a given angle.
- Total radiant power, in watts per square meter (w/m2), falling on a known surface area at a given angle. compare radiance. see also radiometer. irradiance, effective: measure of spectrally weighted radiant power in watts per meter-squared, as determined with a sensor whose responsivity replicates some desired action spectrum. compare irradiance; irradiance, spectral. irradiance, spectral: measure of energy emitted by a radiation source as function of wavelength. units of spectral irradiance are watts per square meter per nanometer (w·m–2·nm–1) and are often plotted versus wavelength. see also spectral power distribution. ishihara plate: trade name for a kind of pseudoisochromatic plate used for color differentiation vision testing.
- Radiant power falling upon a known surface area at a given angle. in nondestructive testing, the unit for irradiance of a uv-a source is microwatt per centimeter squared (?w·cm–2) and maximum irradiance occurs when the source and surface are perpendicular.
