What is spectroradiometer?

It is a gadget to measure the spectral power distribution(SPD) / power of a source. Spectroradiometer is developed to measure spectral irradiance and radiance over various spectral ranges 340 – 780 nm (UVa – VIS) and 640 – 1050 nm (VIS – NIR). They have many advantages for measuring new light source like LED’s, LCD’s, BLU, OLED, mini LED and micro-LED and are being used in photometry, radiometry and colourimetry. These are also called irradiance meter that uses a variable monochromator placed between a light collector and photodetector.

We can measure by this…….

  1. Illumination value in lux
  2. Luminous flux in Lumen
  3. Colour Rendering Index CRI
  4. Colour correlated temperature CCT
  5. Radiant power mWatt
  6. Luminance (cd/m2)
  7. Luminous Intensity (cd)
  8. And many more…

 

All controls/ values available on the software screen of the spectroradiometer

With a button press, you can have the values in seconds…..

Advantages of handheld spectroradiometer….

  1. Lightweight so Portable
  2. Stand-alone means no need to attached to a PC
  3. Best chroma accuracy
  4. Excellent accuracy to measure from high brightness to low brightness
  5. Communication features like Wifi, blue tooth, USB, SD card
  6. Colour LCD touch screen
  7. Battery backup

How does a spectroradiometer work?

Spectroradiometers, are developed to measure the spectral density of illuminant.  They work on the principle of refracting light.

  1. The light source shines onto or through the sample.
  2. The sample transmits or reflects light.
  3. The detector detects how much light was reflected from or transmitted through the sample.
  4. The detector then converts how much light the sample transmitted or reflected into a number.

Applications may include evaluation and categorization of lighting to confirm the lamp specifications.

Types of Spectroradiometers

  1. Handheld Spectroradiometer: They have the capability to measure any light source. The instrument is designed for portable spectroscopy and includes an integrated internal light source.
  2. Full spectrum Spectroradiometer: They can measure between 380nm – 2500nm. They are widely used in Vegetative Stress, Forestry and Drilling Core Analysis, Land and Crop Management, Marine and Wetland Study, Environment Monitor, Geological Study, Mineral Identification,   Surface Color Measurements
  3. UV spectroradiometer
  4. IR Spectroradiometer
  5. Precision /Labgrade spectroradiometer: These are unique as can test all types of light source and have a feature for photobiological safety.
  6. Multi-imaging spectroradiometer
