As an alternative to spacers, adding a negative focal length lens to the camera end of an optical system can
decrease the field of view while maintaining the original working distance specifications. For instance, increasing
the focal length by 2 decreases the field of view by the same factor. Therefore, the 2X extender converts a

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.

M12 μ-Video™ Imaging Lens Accessories
• μ-Video Lens (M12) to C-Mount Adapter With or Without O-Ring
• Lock Nut to Secure M12 Micro-Video Lenses to Most Holders
TECHSPEC® μ-Video™ Imaging Lens C-mount adapters are available both with or without an O-Ring. The ORing
is recommended for use with most μ-video lenses with a full M12 x 0,5 threading, like our TECHSPEC®
μ-Video™ Imaging Lenses. It helps center the lens in the adapter and prevents the lens from defocusing.
For Infinite Conjugate μ-Video™ Imaging Lenses, we recommend using the C-mount adapter without O-Ring
because the thread in either component might only meet the gap of the other.
The counter nut sets the micro-video lens secure in nearly any holder. Due to its slots and holes it can be used
with nearly any spanner wrench. The knurled surface also allows it to be set by hand.
The board holder, made of durable plastic, allows easy integration of micro-video lenses to customer specific
video and sensor devices.
