Description
Bring long-range precision and unmatched low-light performance to your optical setups with our professional-grade 3MP 8mm CS-Mount Fixed Focal Lens. Specifically optimized for 1/2.5″ image sensors, this lens features a narrow 35° horizontal field of view that concentrates pixel density on distant targets, delivering exceptional facial and object recognition. Engineered with an ultra-bright F1.2 aperture, it captures razor-sharp Full HD imagery even in challenging low-illumination environments. Thanks to its advanced Low Distortion Lens architecture and built-in IR Corrected optical coating, it eliminates geometric warping and prevents day/night focus shift. Whether deployed as a dedicated ITS Lens for lane enforcement, a rugged FA lens for assembly inspection, or a high-end Machine Vision Lens, this high-resolving CCTV Lens provides the target detail and reliability that standard wide lenses miss.
Key Highlights & Advantages
- Targeted 35° HFOV for Telephoto Clarity: The 8mm focal length provides a tight 35° horizontal field of view, maximizing pixels on target for long-range capture and detailed tracking without losing digital resolution.
- Extreme Low-Light F1.2 Aperture: Gathers massive amounts of light on 1/2.5″ sensors, drastically decreasing electronic noise and allowing fast shutter speeds on moving production lines or night roads.
- True Geometry Low-Distortion Optics: Delivers a naturally flat image plane with virtually zero geometric bending, severely reducing the need for software dewarping in precise dimension-measuring setups.
- 24/7 Day/Night IR Correction: Specialized multi-layer coating forces both visible light and near-infrared wavelengths onto the identical focal plane, ensuring crisp images during midnight transitions.

Applications & Compatible Equipment
Core Application Scenarios
This narrow-angle Fixed Focal Lens is purpose-built for applications requiring excellent telephoto clarity, flat geometric perspective, and fast shutter speeds under dark conditions. It functions perfectly as an intelligent transportation system (ITS Lens) for multi-lane gate capture, highway vehicle monitoring, and toll booth license plate recognition (LPR) where glare and night shadows interfere. In automated manufacturing, it operates as a specialized FA lens and Machine Vision Lens for parts sorting, box barcode scanning, and label alignment verification where barrel distortion would ruin measurement parameters. Additionally, its tight viewpoint makes it an excellent industrial CCTV Lens for long corridors, structural perimeter fences, bank counters, and high-altitude facial-recognition security gates.

Frequently Asked Questions
Q: Why choose an 8mm lens with a 35° view over a 2.8mm wide-angle lens?
A: A wide lens stretches pixels to cover a room, making distant objects blurry. This 8mm lens concentrates its full 3MP resolution onto a tight 35° target zone, delivering much higher pixel density and clarity for long-range tracking.

Q: Does this 8mm lens require complex software correction for image warping?
A: No. Wide lenses often suffer from heavy distortion, but this 8mm optic functions naturally as a Low Distortion Lens. Its narrow field of view keeps lines straight and flat, saving backend computer processing power.

Q: Can I use this CS-mount lens on a C-mount industrial camera?
A: No, a native CS-Mount Lens cannot focus on a C-mount camera body because its back focal length is too short (12.5mm vs 17.526mm). It must be paired natively with a CS-mount camera thread to function properly.

Q: What is the main benefit of the F1.2 aperture on an industrial line?
A: The F1.2 aperture is extremely bright. In factory automation (FA lens setups), it allows the sensor to gather massive light in milliseconds, enabling ultra-fast electronic shutter speeds to freeze fast-moving items without motion blur.

Q: How does the “IR Corrected” design maintain image sharpness at night?
A: Visible and infrared light focus at different depths. Being an IR Corrected Lens means its glass elements force both light spectrums onto the exact same sensor plane, eliminating day/night focus shift when IR LEDs turn on.

Q: Is the manual focus ring secure enough to withstand production line vibrations?
A: Yes, the manual focus ring comes equipped with an industrial locking screw. Once you lock the mechanism during installation, it will easily withstand heavy factory and machine vibrations without drifting.
