The MR-Dark Field (DKF)Â is made up of our bi-colour LED Modular Ringlight (available in 2 sets of colours and 2 dimensions) and a dark field reflector. The Modular Ringlight and its accessories have been designed with tough production environments in mind: IP65 as standard, overdrive embedded, equipped with a simple remote control capability (selection of colours and quadrants).
Dark field lighting is perfect for creating contrast in applications such as:
By directing light towards the subject at a shallow angle, dark field lighting can be used to create contrast in which the highlighted features appear bright against a dark background – hence the name “dark field”. Most of the reflected light is directed away from the camera (creating the dark backdrop), and only the light scattered off of any features with edges is collected by the camera, creating a striking contrast.
This technique is suited to all materials and is commonly used to highlight surface irregularities, defects, and fine details. The MR-Dark Field is perfect for creating contrast in these applications, even on shiny or reflective surfaces.

TPL Vision is extremely careful about BIN sorting in the selection of LEDs for their products.
Specifically for the Cyan series on this product, the human eye is very sensitive to colour variations. It may appear to the customer that they do not appear the same between two cyan LED products. Despite any noticeable differences, the peak wavelength variation does not exceed 10nm.
Here are the following bandpass camera filters we recommend to fit with the Modular Ringlight:
