• Ideal for Attaching Filters to Imaging Lenses
• Common Mounting Threads
Our Empty Filter Mounts are important accessories for labs and production facilities utilizing machine
vision. The mounts are designed to attach to the most common front filter threads of imaging lenses.
Each mount is designed to hold a specific size filter between 19,5 and 82,0 mm in diameter. Please contact
our Applications Engineering Department for custom filter inquiries.

At long working distances, most lenses are difficult
to fix in bench top applications, and provide fields of
view larger than required. Spacers address these issues
by reducing minimum working distance and by
increasing magnification, which decreases field of
view. The C-Mount Extender Kit includes 0,5 mm, 1
mm, two 5 mm, 10 mm, 15 mm and 40 mm spacers.

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