The effective diameter is approximately 140mm × 140mm! It has a caliber that can accommodate large workpieces.
The "DFC-2" is a dark field collimated illuminator for visual inspection. It can be used at any distance (Work Distance). Even if the WD is changed, the behavior of the light remains almost unchanged, allowing you to work at your preferred position, whether close or far. This light source only refracts/reflects light that hits scratches, foreign objects, dirt, or other abnormalities, making it possible to clearly observe any irregularities (observed under darkroom conditions). 【Features】 ■ Light control: nearly collimated ■ Usable at any distance (Work Distance) ■ The behavior of the light remains almost unchanged even when the WD is changed, allowing you to work at your preferred position, whether close or far ■ The emission color can be switched between RGBW, allowing observation in your preferred color suitable for the work or inspection situation ■ The aperture accommodates large workpieces, with an effective diameter of approximately 140mm x 140mm *For more details, please refer to the PDF document or feel free to contact us.
