UV-Cut Filters & IR-cut Filters - Protect lenses and sensors from dirt and external influences
UV-cut filters and Ir-Cut filters for the industry
The function of the Schneider-Kreuznach protection filters is to prevent lenses from dust, damage, moisture, dirt and UV- and IR-light. The filters don't effect the color characteristic in the visible range.
UV and IR blocking filters fulfill an important function: They reduce the spectrum reaching the sensor to the visible range by blocking the UV light and IR light.
The UV blocking filter blocks the ultraviolet spectrum below approx. 380 nm and thus also reduces the blue component of the light, to which modern sensors are sensitive.
In the case of IR blocking filters, this is correspondingly the case for the long wavelengths, longer than 700 nm. The IR blocking filters block these wavelengths and allow cameras with IR sensitive sensors to operate without interfering wavelengths in the IR range.

Filter Mounts
C-Mount
Defined by 1” (25.4mm) diameter and 32 turns per inch pitch, C-Mount thread is a popular camera mount in machine vision industry. Schneider-Kreuznach offers for most filters a CMT mount option. So that filters can go in any C-Mount based mechanics in vision systems.
Another popular application, CMT mounts can easyly be used for, is placing a filter in front of the sensor into the camera. The extension of the back flange distance has to be considered for imaging applications.
Key features:
• Fits in C-Mount cameras
• Black Anodized Brass
Applications:
• To be mounted in C-Mount cameras
• Vision Systems based on C-Mount mechanics
| Thread | Diameter | Clear | Thickness |
| Aperture | |||
| 1'' - 32 | 25.4 mm | 21.1 mm | 3.6 mm |
SH-Mount
Schneider-Kreuznach offers a variety of mounts with common thread sizes to fit on most camera lens systems. SH-Mount is the standard, when high flexibility is needed. Filters are held by retainer rings. SH-Mounts are extreme robust.
All SH-Mounts have a female and male M-thread, and can be stacked if several filters must be combined.
Key features:
• Stackable
• Robust
• Black Anodized Brass
Applications:
• Mounted on lenses in imaging applications
• Mounted on measurement instruments

SN1-Mount
SN1-Mount was designed for in machine vision industry popular M30.5x0.5 thread. With its high clear aperture, vignetting can be avoided, even for wide angle applications. The filter is glued into the mount, in order to secure it against vibrations when integrated into robots or production lines. It is ideal to be used in automated fabrication.
SN1-Mounts have a male and female M-thread, and can be stacked if several filters must be combined.
Key features:
• Maximum Clear Aperture
• No vignetting
• Stackable
• Robust
• Black Anodized Brass
Applications:
• Mounted on lenses in imaging applications
• Mounted on measurement instruments
