    Abstract: An objective lens (30) for an endoscope comprises a front (41a) and a rear (41b) optical sub-system and an aperture stop (51) there between. The rear optical sub-system (41 b) comprises a compound achromatic component (LR2, LR3) and a rear positive lens (LR4) disposed between said component and the image plane of the system in close proximity to the image plane. The rear positive lens (LR4) satisfies the following condition: fR = 4f where f is the focal length of the total objective lens and fR is the focal length of the rear positive lens (LR4).

    Abstract: An apparatus and a method for cavitating a mixture of a fuel and an additive are disclosed. The apparatus comprises a cavitation stream, the cavitation stream comprising a counter jet device, a jet stroke device and a swirling cavitation device. A mixture of a fuel and additive is arranged to pass through the cavitation stream, wherein the mixture undergoes wave and cavitation processing in the swirling cavitation device. The cavitation apparatus further comprises a resonance chamber and a homogenizer, into which the wave and cavitated mixture is passed to obtain an emulsion of improved homogeneity from an outlet of the homogenizer.
