Key features of the Narrow Bandpass Filters
- Average Transmission: 90 %
- Steep Slopes
- Wavelength Tolerance +/- 3 nm
- Deep blocking / High optical density
Narrow Bandpass Filters - Transmit a small defined wavelength range
Narrow Bandpass filters for the industry
Schneider-Kreuznach magnetron sputtered industrial narrow bandpass filters feature steep slopes for sophisticated applications that require a sharp transition between high transmission and deep blocking at stable cut-on and cut-off wavelengths. The layers are applied by means of magnetron sputtering, a special coating process. Schneider-Kreuznach narrow bandpass filters are RoHS conform. Custom sizes are available on request.

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
