Named for their shape, “dome” lights excel at delivering diffuse light in larger fields of view. The molded fiberglass hemisphere reflects light onto your part from many angles. Shiny and irregular objects can be imaged free of shadows and hot spots.

When imaging mirror-like surfaces, we suggest combining this light with one of our diffuse axial lights. Mount our diffuse axial light between the dome’s view port and a camera lens for optimal results.

Our price includes a light controller, a quick-disconnect connector, and a 4 meter cable as standard. The compact controller may be mounted on a DIN rail, and uses 24 VDC power. It has both PNP and NPN strobe inputs with a 3 microsecond response. As an option we offer controllers with a potentiometer, or analog input, to control light intensity. (Never connect this light directly to power.)

Please contact us if you’re interested in a super-high output version, various controller options, a longer cable, or a high-flex cable.
