DF241-39525I3S | DF241 Dark Field Ring Light, 395nm Ultraviolet (UV) iCS3 - I3S

Part: DF241-39525I3S

The DF241 very low angle Dark Field ring light was designed for the most demanding surface inspection applications. It is best suited for use on flat, specular reflective surfaces that require the lowest angle of incidence to contrast minor surface defects, such as scratches or pits. To achieve the proper light geometry, this light head must be positioned no more than 25 mm from the surface for optimal results. The DF241 ring light differs from the DF196 Dark Field light in that the LEDs are physically focused to a point in space, rather than utilizing a focusing lens. The precision LED aiming produce a thin, yet very uniform slice of light whose footprint on target is quite small compared to the light head diameter.
