TPL Vision : MR-DOME light for machine vision

The MR-DOME is compound of a bi-colour LED lighting ring (2 sets of colours and 2 dimensions) and a dome reflector.

It has been designed with tough production environments in mind: IP65 as standard, overdrive embedded, simple remote control capability (selection of colours and quadrants).

The MR-DOME provides a highly-diffused light source which has no component of direct lighting. The light intensity is lower than with other illumination techniques but will have a high degree of homogeneity.


  • objects are highly reflective (shiny),
  • the target area is subject to shadowing with direct or low angle light sources,
  • the target area has some very un-even surfaces.

The MR-DOME should be mounted close to the object of interest to maximise the effect of the illumination style.

To minimise the «black dot» visible within the image, the diameter of the hole at the top of the dome should also be minimised. This can be done using the supplied plastic caps.

Surface FX Compatibility

la société TPL Vision est particulièrement vigilante sur le choix de BIN des leds qui composent ses éclairages.
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:

  • White LEDs: no filter required
  • Infrared LEDs: LP 830 (
  • Red LEDs: BP 635 (
  • Cyan LEDs: BP 505 (

We advise using bandpass filters from MidOpt:
