For example, when you shine white light into a prism, you observe a band of colours on the other side. This process isn't magic, but rather a scientific phenomenon known as dispersion of light.

Newton's experiments with prisms led to the understanding that natural (white) light is composed of a range of differently coloured beams.

The right lighting is key for any image processing system. It helps determine whether an inspection task is handled efficiently or not.

The right illumination is critical in a vision system. Properly combining lighting with the camera and lens ensures the best possible results in your application.

Different prism angles and materials lead to variation in how dispersed or close the bands of colours are. This means the refraction and hence the spectrum witnessed can vary based on the properties of the prism.

Ring lights are suitable for many different image processing tasks. They are most commonly used as a bright field configuration in the inspection of matte, non-reflective materials.

Our Lighting Advisor provides individual product recommendations by guiding you step by step to a selection of suitable lighting and components. Select the lighting for your vision system as early as possible during your design process.

The rainbow effect in a prism is explained by the phenomenon of dispersion of light into different colours, with each colour, or wavelength of light, bending at a different angle.

Light slows down and refracts or changes direction when it enters the prism. When it exits, it speeds up and refracts away from the normal. Different colors of light refract differently because they have different refractive indices, causing white light to split into a spectrum of colors.

The right lighting in a computer vision setup significantly impacts image processing results. Here, we explain the key factors that contribute to optimal lighting.

A light prism is a transparent optical element with flat, polished surfaces that refract, or bend, light. It's typically a polished glass triangle and the light waves passing through it are both slowed and bent.

In the domain of optics, a light prism is a transparent optical element with flat, polished surfaces that refract, or bend, light. Its form is typically a polished glass triangle and the light waves passing through it are both slowed and bent.

It can be challenging to select the right illumination for your application. With the wide range of lighting options on the market, it is crucial to choose the right illumination early in the design phase to save cost and integration efforts. But how do you select the optimal lighting type for your vision application?

Newton's experiments with prisms in the 17th century led to a deeper understanding of the nature of light, proving that natural (white) light is composed of a range of differently coloured beams. This was a significant leap in the scientific understanding of light.
