Share color choices for machine vision light sources

In the machine vision industry, the common types of light sources are ring light source, AOI custom light source, shadowless light source, bar light source, coaxial light source, bottom backlight, side backlight, bottom open light source, bar combination light source, spherical integral light source, linear light source, etc., but how much do you know about the color selection of light source? The following Xinxiwang will explain to you:

White light source (W): White light source is usually defined by color temperature, the color with high color temperature is bluish (cold color temperature "5000K"), the color with low color temperature is reddish (warm color temperature "3300 and 5000K"), between which is called intermediate color, white light source has wide applicability and high brightness, and is used more when shooting color images.

Blue light source (B): The wavelength of the blue light source is between 430-480, applicable products: silver background products (such as sheet metal, turning parts, etc.), metal prints on film.

Red light source (R): The wavelength of the red-light source is usually between 600-720, which can pass through some darker objects, such as the hole positioning of the transparent soft board with black substrate, the circuit detection of the green circuit board, the thickness detection of the translucent film, etc., and the use of red light source can improve the contrast.

Green light source (G): The wavelength of the green light source is 510-530, between red and blue, mainly for red background products and silver background products.
