Part of the Monster series manufactured by Spectrum Illumination, this ring light is typically mounted around a camera lens for bright-field illumination. However, it can also be mounted off-axis as a large spot light.

This light is best for projects requiring a lot of light. When your parts are moving fast, you need to light a large area, or you have a long working distance, this is the light to consider. It can be mounted 12" to 20' from the object to be imaged. LED optics and diffuser options are available that make it possible to obtain closer working distances and/or larger coverage areas.

This light includes a light controller, a shower glass diffuser, 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 controller options, a different diffuser material, different LED optics, a longer cable, or a high-flex cable.
