Description
This professional 6mm CS-mount CCTV lens delivers exceptional 3MP resolution packed into an ultra-compact mechanical housing with a 22.23mm TTL. Optimized for 1/2.5″ image sensors, it features a versatile 56° horizontal field of view and a fast F1.8 fixed iris to ensure crisp image capture in diverse lighting environments. Engineered with premium multi-coated optics and full IR correction, this fixed focal industrial lens maintains sharp focus across day and night cycles without chromatic drift. Its outstanding 0.1m minimum object distance (M.O.D.) makes it a top-tier choice for high-precision, close-range inspection within space-constrained automation and surveillance systems.
Product Highlights
-
- Premium 3MP Optical Clarity: Engineered to support up to 3 Megapixel resolution, delivering sharp edge-to-edge contrast and resolving intricate details that lower-grade lenses distort.
- Ultra-Short 0.1m Close Focus: Boasts a remarkable 0.1-meter Minimum Object Distance, making this machine vision lens exceptionally powerful for macro capturing and close-up product inspections.
- Ultra-Compact Form Factor: Featuring a highly optimized 22.23mm Total Track Length (TTL), it easily integrates into small-footprint industrial camera housings and low-profile smart equipment without adding unnecessary bulk.
- Day & Night IR-Corrected Performance: Built-in IR corrected lens technology aligns visible and infrared light paths perfectly, eliminating blurry night-time video footage and preventing tedious focus recalibrations.

Target Applications & Device Compatibility
Core Application Scenarios
The unique structural design of this CS-mount fixed focal lens makes it ideal for compact, high-precision environments. It excels in ATM kiosk monitoring, self-service retail terminals, and indoor corridor access control where its 56° horizontal FOV provides a clear portrait view without wide-angle distortions. Furthermore, thanks to its micro-focus capabilities (M.O.D. 0.1m) and extremely low profiles (22.23mm TTL), it serves as a highly efficient FA lens for electronic component assembly line checking, QR code scanner integration, pharmaceutical pill sorting, and close-range robotic arm vision systems operating in highly confined factory automation workspaces.

Frequently Asked Questions
Q: Can this lens be used on standard 1/3″ or 1/2.8″ sensors?
A: Yes. It is fully backward compatible. When paired with smaller sensors, the field of view narrows slightly, with zero dark corners or vignetting.
A: Yes. It is fully backward compatible. When paired with smaller sensors, the field of view narrows slightly, with zero dark corners or vignetting.
Q: What are the advantages of the 22.23mm TTL?
A: Total Track Length (TTL) is incredibly short. It allows your entire camera assembly to remain ultra-compact for tight machine or dome integration.

Q: Does a fixed F1.8 iris mean I cannot adjust exposure on the lens?
A: Correct. The aperture is mechanically fixed. Exposure control is handled electronically via the camera’s shutter speed or auto gain control (AGC).
A: Correct. The aperture is mechanically fixed. Exposure control is handled electronically via the camera’s shutter speed or auto gain control (AGC).
Q: Can I adjust the focus, or is it a completely fixed lens?
A: Zoom is fixed, but it features a precise manual focus ring. You can fine-tune clarity from infinity down to a close-range 0.1 meters.

Q: Why is “IR Corrected” important for this lens?
A: It eliminates chromatic shift. Visible and infrared light focus on the exact same plane, keeping night vision just as sharp as daytime footage.

Q: Is this lens suitable for long-range license plate recognition?
A: No. With a 56° horizontal FOV, it excels at mid-to-close-range tracking. For long-range multi-lane highways, a 12mm or higher lens is preferred.
