O-Z Filters, distance rings, converters

In the O-Z accessory series, you will find the appropriate functional extensions for our lenses with filters, distance rings and converters.

Spacer rings / sets and accessories

Spacer rings are used between the camera and the lens in order to reduce magnification while reducing the working distance. When working with defined installation spaces, distance rings are essential for attaining the necessary image fields with a given working distance.


The rear converter lens increases magnification without changing the working distance and is simply inserted between the camera and the lens.


The filters for our lenses are of the highest quality and are available for an extremely wide variety of applications. Whether polarization filters, bandpass filters, cutoff filters or lens protection glasses - di-soric has the right accessories for nearly all applications in the area of optics for image processing and identification.
