Description

Hexa-Black noise reduction extension tubes are used as spacers to increase the image distance when using SM1, C-Mount and CS-Mount instruments for cameras and camera lenses.

The unique black material has nearly zero specular reflection at grazing angles, allowing higher SNR and lower noise in the system.

This range extender used in between lens and a camera to extend the focal length and increase the effective aperture of the lens, what will allow to focus the system at much closer distance.
