6mm CS-Mount 5MP Wide Angle IR Corrected Lens

This 6mm CS-mount wide angle lens is designed for 2/3″ image sensors and delivers a 100° diagonal field of view, with 80° horizontal and 60° vertical coverage. Featuring 5MP resolution, a fast F1.4 aperture, fixed focal length, manual focus, and IR-corrected optical performance, this lens is well suited for wide-area CCTV surveillance and professional security monitoring applications.

CS-Mount Lens Core Highlights

• 6mm Wide-Angle Focal Length – Provides 100° diagonal and 80° horizontal FOV for broad surveillance coverage.
• 5MP Resolution – Supports detailed imaging for compatible 2/3″ security camera systems.
• Fast F1.4 Aperture – Provides strong light-gathering capability for indoor and low-light monitoring environments.
• IR Corrected Optical Design – Helps maintain more consistent focus when cameras operate across visible and near-infrared illumination.
• CS-Mount Fixed-Focal Design – Provides a conventional interchangeable interface for professional CCTV and security camera platforms.

CS-Mount Lens Applications

Wide-Area CCTV Surveillance

The combination of a 6mm focal length and 80° horizontal field of view provides broad scene coverage while retaining a more controlled perspective than an ultra-short fisheye lens. This makes the lens suitable for fixed surveillance positions where the camera needs to monitor a relatively large area from a defined installation point.

Designed for wide-angle CCTV surveillance and fixed-position security monitoring applications.

Potential installation environments include building entrances, retail stores, offices, reception areas, corridors, commercial facilities, and indoor public spaces.

Indoor Security Monitoring

The F1.4 aperture provides strong light-gathering capability for environments where illumination may vary between bright and dim conditions. It can be useful for indoor surveillance cameras operating in commercial buildings, retail environments, warehouses, offices, and access-control areas.

The fixed iris configuration provides a consistent aperture while manual focus allows installers to optimize the optical focus during camera deployment.

For additional surveillance configurations, TOWIN’s CS-Mount Lenses portfolio provides a range of lenses for professional CCTV and security camera integration.

IR-Assisted Surveillance

IR correction is one of the key optical features of this lens. Security cameras frequently operate under both visible illumination and near-infrared illumination, particularly when IR LEDs are used for nighttime monitoring. An IR-corrected optical design helps reduce wavelength-related focus shifts and supports more consistent image focus across different illumination conditions.

This makes the lens suitable for CCTV systems that require reliable day/night imaging without changing the optical assembly.

Commercial & Building Monitoring

The 80° horizontal FOV is useful for monitoring defined but relatively broad areas such as store interiors, building lobbies, hallways, reception zones, and access points. The wide-angle configuration can reduce the number of cameras needed to observe a given indoor scene when compared with narrower focal-length configurations, depending on installation geometry.

Close-Range Wide-Area Observation

Although the M.O.D. is not specified in the supplied parameters, the wide FOV makes the optical configuration suitable for scenes where the camera must capture a relatively broad area from a fixed position. Actual installation distance should be evaluated together with sensor size, camera mounting height, and target dimensions before deployment.

Frequently Asked Questions

Q: What type of camera is this 6mm CS-mount lens designed for?
A: This lens is designed for CS-mount camera systems using 2/3″ image sensors, with applications primarily focused on CCTV, security surveillance, and wide-area monitoring.

Q: What field of view does the lens provide?
A: The lens provides a 100° diagonal field of view, 80° horizontal FOV, and 60° vertical FOV, making it suitable for broad fixed-position surveillance coverage.

Q: Is this a fixed focal length lens?
A: Yes. The focal length is fixed at 6mm and the zoom configuration is fixed, providing predictable framing after installation.

Q: What is the advantage of the F1.4 aperture?
A: The F1.4 aperture provides strong light-gathering capability, which can help support image brightness in indoor, dim, or changing lighting environments.

Q: Why is IR correction important for CCTV cameras?
A: IR correction helps reduce focus shifts associated with changes between visible and near-infrared illumination. This is particularly useful for CCTV systems equipped with IR illumination for nighttime monitoring.

Q: Is this lens suitable for wide-angle surveillance?
A: Yes. The 80° horizontal and 100° diagonal FOV provide broad coverage for indoor security, building monitoring, retail surveillance, and other fixed-position applications.

Q: Is this a low-distortion lens?
A: No. The specified distortion is -29%, so this lens should not be marketed as a low-distortion optical solution. Its primary advantage is broad field of view rather than geometric accuracy.

Q: Can this lens be used with a 5MP camera?
A: Yes. The lens is specified for 5MP resolution and 2/3″ image sensors, making it suitable for compatible 5MP CS-mount camera systems.
