Schneider-Kreuznach Longpass Filter LP 460 HT

Schneider-Kreuznach longpass filters deliver high transmission and precise cutoff performance for use in industrial and machine vision applications. Thanks to their steep slopes, flat surfaces, and robust AR coatings, these filters ensure accurate results and minimal reflections even under demanding conditions. 

The Schneider-Kreuznach LP 460 HT magnetron sputtered industrial longpass filter features steep slopes and high transmission at stable cut-on wavelengths. The very flat surface makes it ideal for high end machine vision systems in factory automation. All longpass filters come with superior antireflection coating. Schneider-Kreuznach longpass filters are RoHS conform. Custom sizes are available on request.

Mounts for Industrial Optical Filters

C-Mount

Defined by 1” (25.4mm) diameter and 32 turns per inch pitch, the C-Mount thread is a popular camera mount in machine vision industry. Schneider-Kreuznach offers a C-Mount option for most filters. So filters can go in any C-Mount based mechanics in vision systems.

Another popular application, C-Mounts can easily 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 of C-Mount Filters:
Fits in C-Mount cameras
Black Anodized Brass

Applications of C-Mount Filters:
To be mounted in C-Mount cameras
Vision Systems based on C-Mount mechanics

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 of SH-Mount Filters:
Stackable
​​​​​Robust
Black Anodized Brass

Applications of SH-Mount Filters:
Mounted on lenses in imaging applications
Mounted on measurement instruments

SH Filter-Mount

 

SN1-Mount

The SN1-Mount was designed for the in machine vision 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 SN1-Mount Filters:
Maximum Clear Aperture
No vignetting
Stackable
Robust
Black Anodized Brass

Applications SN1-Mount Filters:
Mounted on lenses in imaging applications
Mounted on measurement instruments

Thread Diameter Clear Thickness

SN1-Mount

The SN2-Mount is designed for polarizers and achieves highest possible aperture, avoiding vignetting in machine vision systems. Its unique locking mechanism fixes the correct orientation, even in typical industrial environment. The filters are glued into the mount to secure them against vibrations when integrated into robots or production lines. Ideal for use in automated fabrication.

SN2-Mounts have a female and male M-thread, and can be stacked if several filters must be combined.

Key features:
