Description
Achieve absolute optical control and structural stability with our industrial-grade 5MP 15-30mm C-mount IR Corrected lens. Masterfully engineered for large-format 2/3″ image sensors, this high-resolution zoom lens provides a versatile 15-30mm telephoto range with a targeted 34° to 18° horizontal field of view. Featuring a fast F1.4 large aperture and independent manual adjustment rings for iris, focus, and zoom, this lens guarantees exceptional geometric fidelity with distortion under 1%, delivering pixel-perfect images from standard visible light to active infrared night illumination.
Key Product Highlights
- Flexible 15-30mm Telephoto Zoom: Offers seamless adjustment between a 34° mid-range overview and a focused 18° telephoto frame, allowing precise on-site target framing without swapping lenses.
- Virtually Distortion-Free Optics (<1%): Keeps optical distortion under 1% across the entire focal range, ensuring superb geometric linearity for high-precision metrology and automated inspection.
- Ultra-Bright F1.4 Manual Aperture: The massive F1.4 opening floods the sensor with light, while the lockable manual iris ring allows engineers to fix precise light intake parameters for consistent exposures.
- Seamless IR-Corrected Day/Night Tracking: Specialized IR corrected lens multi-coatings eliminate focus shift when transitioning between visible daylight and infrared night vision, maintaining crisp 5MP clarity 24/7.

Applications & Compatible Equipment
This professional varifocal day&night lens is custom-built for high-end industrial automation, laboratory testing, and fixed-perimeter monitoring. It serves as an excellent machine vision lens for automated optical inspection (AOI), long-distance packaging validation, electronic component measurement, and robotic vision stations requiring compact C-mount lenses with lockable mechanical adjustments. Furthermore, its ultra-bright F1.4 aperture and 15-30mm range make it highly valuable as an ITS lens for toll booth surveillance, parking lot entry tracking, and medium-range license plate recognition (LPR/ANPR) systems where exposure parameters must stay securely locked against vibration.

“Designed for high-precision factory automation, low-distortion telephoto machine vision, and fixed-aperture security applications.”
Frequently Asked Questions
- Q: Why is a manual iris preferred over an auto iris for this model?
- A: In precise industrial testing and metrology, exposure consistency is critical. A manual iris lens allows technicians to set a fixed aperture (up to a bright F1.4) and lock it down completely, preventing exposure fluctuations that can confuse automated vision software.
- Q: How do the manual adjustments handle heavy industrial machinery vibrations?
- A: The lens barrel is equipped with industrial thumb locking screws for all three rings (Zoom, Focus, and Iris). Once calibrated on-site, tightening these screws prevents any settings drift or mechanical shifting caused by robot arm movements or factory vibrations.
- Q: What is the benefit of keeping distortion under 1% on a 15-30mm zoom lens?
- A: Varifocal zoom lenses typically suffer from severe barrel or pincushion warp. Keeping distortion under 1% classifies this model as a professional low distortion lens, ensuring shapes, lines, and part measurements remain geometrically accurate across the entire zoom range.
- Q: Can I use this C-mount lens on a standard CS-mount security camera?
- A: Yes, you can. Since a C-mount lens has a longer back focal length requirement, you simply need to screw on a standard 5mm C-to-CS adapter ring between the lens and the CS-mount camera body to achieve correct focus.
- Q: What does the “IR Corrected” designation mean for 24/7 use?
- A: Visible light and Infrared light focus at different optical points. Standard optics go blurry when night-vision IR lamps turn on. This IR corrected lens targets both wavelengths onto the exact same focal plane, keeping daytime color footage and nighttime infrared footage equally crisp.
- Q: What is the Minimum Object Distance (M.O.D.) for this lens?
- A: The M.O.D. is an impressive 0.2 meters (20cm / approx. 8 inches). This remarkably close focus allows the lens to perform detailed macro inspections on manufacturing lines even when utilizing the full 30mm telephoto focal length.
