Acktar Hexa-Black™ C-Mount Noise Reduction Extension Tubes

Acktar Hexa-Black™ Light Absorbing Technology
Reduce Stray Light and Noise in Imaging Systems
Near Zero Specular Reflectance at Grazing Angles
Stray Light Rejection Ratio up to 8 x 10^-7

Acktar Hexa-Black™ C-Mount Noise Reduction Extension Tubes are used to increase the image distance in C-Mount imaging systems where stray light is a concern. Featuring Acktar’s Hexa-Black™ technology, these extension tubes provide extremely high absorbance of stray light at grazing angles up to 88°. The ultra-black Hexa-Black material is designed to have wide-band absorption from the UV to the MWIR, providing a stray light rejection ratio up to 8 x 10^-7. Acktar Hexa-Black C-Mount Noise Reduction Extension Tubes enable higher signal-to-noise ratios (SNR) and lower noise in imaging systems than standard anodized aluminum tubes. Multiple lengths are available with male/female C-Mount threads at opposite ends; please contact us if your application requires a custom sized noise reduction extension tube.
