Thanks to its design, the Irida-180 ring illuminator by Büchner covers numerous inspection tasks. Two separate LED light rings are concealed under the inwardly curved diffuser, one for the visible light colors RGB and a second for UV and infrared light. By arranging them in two closely spaced rings, it was possible to increase the number of LEDs, which ensures a much more homogeneous illumination. The two light rings are additionally divided into four circle segments.
The BP450 filter by Midwest Optical is for enhancing viewing of subjects illuminated by a 450nm blue LED.
