Part of the MicroBrite™ family of high performance, compact machine vision lights.
Provides diffuse illumination at a low angle to cast shadows used to identify surface defects, embossed text, etc.
This ring light is more diffuse and less directional than the DF196.
Can be used to produce a bright field effect when the outer diameter is smaller than the working distance.
Available in 4 sizes with an intensity of 47klux (working distance of 64mm with DF198-180).

Manufactured By: Advanced Illumination

More

The MicroBrite DF198 Series Dark Field ring lights are designed to provide diffuse, medium to low angle of incidence illumination when positioned at working distances less than or equal to the light’s diameter.

Owing to its curved diffuser, the DF198 Series is also suitable for applications requiring diffuse Bright Field lighting when the light is positioned at working distances longer than its diameter.

The unique combination of 5 available light diameters and a variety of possible working distances offers potential solutions for multiple light geometries and intensity and pattern size on target options in a single light head.
