Print inspection on transparent bottle
Inspecting white characters printed on the transparent bottle utilizing spot lighting OPS-S series and machine vision.
By lighting at small area by two spot lighting with condensing lens, the characters can be detected without affection by printed characters at opposite side of the bottle.

Checking cavity number on the connector for automotive
Detecting the cavity number of the connector utilizing coaxial lighting.
Thanks to OPX's highly uniform illumination with a narrow directivity angle light, small cavity number can be detected clearly. Because the illumination is highly uniform, the installing position of the lighting can be flexible even at the short range area.
