What is spectroradiometer?

It is a gadget to measure the spectral power distribution(SPD) / power of a source. Spectroradiometer are 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 colorimetry. These are also called irradiance meter that uses a variable monochromator placed between a light collector and photo detector.

We can measure by this…….

Illumination value in lux
Luminous flux in Lumen
Colour rendering Index CRI
Color correlated temperature CCT
Radiant power mWatt
Luminance (cd/m²)
Luminous Intensity (cd)
And many more…

All controls/ values available on software screen of the spectroradiometer

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

spectroradiometer values

Advantages of handheld spectroradiometer….

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

What is difference between radiometer, spectrophotometer and spectroradiometer?

S.No	Radiometer	Spectrophotometer	Spectroradiometer
Def.	It is an instrument to measure radiant flux	A spectrophotometer is mainly used to measure f transmittance or reflectance of solutions.	A spectroradiometer to measure spectral radiance or irradiance across various spectral ranges.
Spectral range	UV and IR	Visible, Near IR, Near UV	Visible and UV
Features	Inexpensive, portable, less accurate	More accurate than radiometer	Highly accurate, portable, stand-alone.
Units	Watt	Cd	Cd, lux, lumen, w/m3 etc…
Measure	Radiant power	Light beam intensity and colour	Photometry, colorimetry
Consist of	Sensor, filters	Single beam and double beam, collimator, prism grating , cuvette	Lens or diffuser, monochromator, detector and control and logging system
Application	IR and UV measurements	Visible , near UV and near IR measurements	Visible,UV

How does a spectroradiometer works?

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

The light source shines onto or through the sample.
The sample transmits or reflects light.
The detector detects how much light was reflected from or transmitted through the sample.
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

Hand held Spectroradiometer: They have the capability to measure any light source. The instrument is designed for portable spectroscopy and includes an integrated internal light source.
Full spectrum Spetroradiometer: 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
UV spectroradiometer
IR Spectroradiometer
Precision /Labgrade spectro radiometer: These are unique as can test all types of light source and have a feature for photobiologicalsafety.
Multiimaging spectro radiometer
