A spectroradiometer is a light measurement tool that is able to measure both the wavelength and amplitude of the light emitted from a light source. Spectrometers discriminate the wavelength based on the position the light hits at the detector array allowing the full spectrum to be obtained with a single acquisition.

Spectrometers or spectroradiometers can quickly measure light energy over a range of wavelengths. These devices commonly use either a fixed filter technology and an array detector or a scanning filter technology and a single element detector.

Spectroradiometers are used to measure the spectral power distributions of light sources, monitors, and other illuminants. They are used to evaluate and categorize commercial and residential lighting, and to calibrate liquid crystal displays (LCDs) and cathode ray tube (CRT) displays on laptop computers and high definition televisions (HDTVs).

Renowned for their reliability, accuracy, and ease of use, these spectrometers are optimized for analyzing the spectral properties of materials in the visible, near-infrared (NIR), and short-wave infrared (SWIR) regions. - Broad Spectral Range: Coverage from 350 nm to 2500 nm, enabling analysis across visible, NIR, and SWIR wavelengths.

Apogee offers two unique types of spectroradiometers. The lab spectroradiometer is calibrated for use in laboratories and measures wavelengths between 300 and 1000 nm. The new Apogee handheld spectroradiometer takes portable measurements in any environment and measures wavelengths between 380 to 780 nm.

Spectroradiometers are spectrometers calibrated to output spectral measurements in absolute units (e.g., energy flux density in W m -2 nm -1 or photon flux density in µmol m -2 s -1 nm -1 ). Apogee instruments offers two types of spectroradiometers, the Lab Spectroradiometer and the Field Spectroradiometer.

2018年1月15日 · It discusses that spectroradiometers measure the spectral power distribution of light sources over different wavelengths and areas. The key components are input optics to gather light, a monochromator to separate wavelengths, and a detector to measure intensity.

The ZLX-ES series spectro-radiometer systems are designed for the accurate measurement of the radiant power emitted from a light source as a function of wavelength. Typical examples include the measurement of LEDs, tungsten and fluorescent lamps.

Spectroradiometers bring the advantages of radiometers and spectrometers together and cancel their disadvantages by being a portable, simple tool that can detect and measure a wide …
