Acktar Hexa Black™ Noise Reduction Extension Tubes are space-qualified tubes primarily used as spacers to increase the image distance when using SM1-Mount, C-Mount, and CS-Mount instruments for cameras and camera lenses.
With it's unique black material, the product has nearly zero specular reflection at grazing angles, which leads to higher signal-to-ratio (SNR).
It has a wavelength range between 200nm – 5µm and can be used in between a lens and a camera to extend the focal length and increase the effective aperture of the lens.
