Resources

LTRNOB series are LED ring illuminators specifically designed for a wide range of Opto Engineering® products.

Especially the oblique type models perfectly fit Opto Engineering® 360° view optics.

Every illuminator is equipped with a mechanical interface which makes it very easy to mount it on different lens types.

These products enable the optimal illumination geometry for the most common applications of their matching lens.

KEY ADVANTAGES

  • Mechanically fitting Opto Engineering® optics
    Each lens integrates specific mechanical interfaces.
  • Specific illumination geometry
    Illumination path matches Opto Engineering® lenses viewing angle and numerical aperture.
  • High performance to price ratio
    Cost-effective, without quality compromises.
