Schneider-Kreuznach Protection Filters

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.

What is the function of the filters?
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.

Where are the filters used?
In industrial applications, UV-Cut and IR-Cut filters are used in a wide range of applications, including machine vision and in the traffic and suveillance sector.

Applications & Markets of UV-Cut and IR-Cut Filters


Machine vision

Machine vision
 
 

Machine vision enables machines to recognise objects, patterns and other visual features through the integration of lenses and image processing.
 

Surveillance

Traffic and
surveillance

Traffic and surveillance systems use cameras and image processing to monitor and manage traffic flow and public safety.

 

Lens protection

Lens protection
 

To protect lenses from scratches and external influences, optical filters are used.


 

Sensor protection

Sensor protection
 

Optical filters are used to protect sensors from damage or interference by selectively blocking or reflecting certain wavelengths of light.

Mounts for UV-cut and IR-Cut filters

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

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

Thread Diameter Clear Thickness

SH Filter-Mount

 

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
