The purpose of machine vision illumination is to control how the object appears to the camera. Firstsight Vision supply a range of flexible lighting solutions, including sources, guides and illuminators. The light sources include Xenon strobe and arc lamps as well as computer controlled DC regulated Halogen sources.Choices of standard and custom light guides are available with PVC, steel and high temperature sheaths and quartz, plastic and glass fibre bundles. Different lighting techniques can be implemented using appropriate illuminators. These include ring lights, back lights, dark field illuminators, slit guides, co-axial camera lenses, diffuse lighting adapters and microscope adapters.
In machine vision applications the importance of illumination is almost always underestimated. Specialist illumination is sophisticated and there is science to understanding how and why a certain type of illumination is suited to an application.
When selecting illumination products:
1. Identify the most suitable technology (LED, fluorescent or fibre optic and laser)
2. Choose a suitable illumination technique & choose a product
3. Choose the corresponding power supply / light source

Maxlites, Continuous Diffuse Illuminators (CDI)
A combination light, comprising on-axis technology and a small dark-field ringlight.
Can be used for applications
requiring 2 different techniques.
Continuous Diffuse Illuminators (CDI)
The highest level illumination performance available. It has been designed
for the most difficult applications and combines off-axis spherical reflected
light and on-axis
light to provide light incident from all angles. This illuminator is sometimes referred to as 'Cloudy Day'. Available in a variety of sizes and types.
A special variety of miniature ringlight, usually used in combination with remote (micro) head cameras. Available in various sizes and types.
These illuminators are used for illuminating reflective objects. They use a beam splitter to eliminate the reflection of the camera lens or the illuminator itself in the resulting
A very simple, general purpose illuminator. Provides light from a specific direction onto the field of view. The light direction is dependent on mounting position and may be used as a bright-field illuminator for diffuse surfaces, as a dark-field illuminator (creating shadows and specular reflection) or as a small backlight (when mounted behind the part). Available in a number of colours and formats.
