Photometers
Instruments used to measure the intensity of scattered light.
What Is a Photometer?
Photometers are instruments that measure electromagnetic radiation, from ultraviolet to infrared, including the visible spectrum. They convert light into electricity using a photoresistor, photodiode, or photomultiplier. For measuring at a defined wavelength or for analyzing the light’s spectral distribution, the light may also be passed through a filter or a monochromator.
What Is a Photometer Used for?
A light meter, a specific type of photometer, is used to measure the amount of light present. In photography, light meters help the photographer determine the correct shutter speed and f-number selection for the desired exposure. They are also used for cinematography, scene design, architectural lighting design, and for plant growth systems.
Science-related applications for light meters include the measurement of:
- UVA (315 to 400nm) and UVB (280 to 315nm) light for phototherapy or skin treatment
- UVC (100 to 280nm) output from disinfection and sterilization lamps (readout in watts per square centimeter)
- The brightness (luminance) of exit and other signs or displays
- Light source emissions that may help plants grow
- The UV light emission used to harden glues, plastics, or other protective coatings (readout in joules per square centimeter)
- Daylight or output from tungsten, fluorescent, or mercury lamps
Most light meters are portable and may measure light in only a defined section of the spectrum, such as UV light . Some light meters allow you to select the light source and report the results in one or more of the common units: lux, foot-candles, lumens, candelas, or candelas per square meter. Other units include watts or joules per square centimeter.
Implen OD600™ Photometer, EU Plug
Measure cell density and turbidity, fast and accurately with the lightweight, portable Implen OD600 instrument. No sample dilution required due to large dynamic detection range. No adapters required as the Implen OD600 sample holder design that is compatible with majority of tubes and cuvettes.
WTW™ Spectrophotometer photoLab™ 7600 UV-VIS
The spectrophotometer photoLab™ 7600 UV-VIS combine routine analysis with spectral analysis and pioneering procedure OptRF. For the standard parameters COD, nitrate and nitrite, a spectrum in the UV range is evaluated by means of complex algorithms which are based on reference spectra. The result is put out directly as concentration reading, without the use of reagents. No potassium dichromate, no digestion - for quick testing.
