Polarized Ring Light (bright-field), 90mm, white, 24V / 9W

Our special polarized ring light will remove the reflections normally caused by a ring light on the product. This ring light has a polarizer in front of the LEDS and a polarizer that is 90 degree turned in front of the lensmount. This prevents direct reflections from the LED’s of the ring light into the camera. Please note that by filtering out the direct reflected light, a lot of light intensity is lost. Depending on your product you could expect an exposure time that is at least 2x longer, but in some situations also 5-10 times longer. For stationary inspection it’s a perfect solution. When inspecting moving objects, where short shutter times are required, we advise you to contact us.

The polarized ring light can easily be mounted onto a c-mount lens that has a M27 x P0.5 lens thread (see list below for our lenses).
