Epson previews new compact spectroscopic camera

Epson has developed a compact, lightweight spectroscopic camera that can be integrated in manufacturing lines to automate colour inspections. It says the new camera, which captures light across the visible spectrum, will be launched in the 2020 fiscal year ending March 2021.

“The RGB cameras currently used in these inspections are unable to capture detailed colour information and are not always able to distinguish between subtle differences in colour,” says Epson. “Consequently, most visual inspections relied on human colour perception. However, colour perception varies among individuals, and human error puts manufacturers at risk of shipping defective goods. Time and cost constraints make colour management an issue in many industries. Spectroscopic cameras have traditionally been large and expensive, and those equipped with line sensors may have to composite images after scanning, adding to the time and expense.

“Epson has developed an optimal solution for colour management processes with a compact, lightweight spectroscopic camera that can be integrated into manufacturing lines, that can automate and quantify inspections, and output images without the time and trouble of compositing. This spectroscopic camera will enable manufacturers to manage colour in their manufacturing processes more easily than ever before.”

Integral field spectroscopy. Can focus on an area, measure the colours, and distinguish colours of a target object within the visible light range.

Image processing functions needed on manufacturing lines can be used along with spectral imaging functions.


Wavelength range      400 nm to 700 nm

Number of bands        16

Wavelength resolution           45 nm

Image resolution         1,024 x 768 (XGA)

Size      Dimensions to be announced later

Weight 175 g

Lens mount     C-mount

Operating temperature range            +5 to +40℃

Epson will be demonstrating the spectroscopic camera on the Epson booth  S1-02 at International Robot Exhibition 2019, to be held at the Tokyo Big Sight (Tokyo International Exhibition Centre) from 18-21 December 2019.
