Description
Introducing our high-performance 4.2mm F2.4 3MP M12 ultra-macro pinhole lens, the ultimate optical engineering solution for high-precision, close-up covert surveillance and smart embedded hardware frameworks. Purpose-built for large-format 1/2.7″ image sensors, this specialized macro pinhole board lens breaks through physical design barriers by focusing flawlessly at a point-blank 0.1m minimum object distance (M.O.D.). Delivering a crisp 3 Megapixel resolution and an optimized 77° horizontal field of view with near-zero distortion, it captures razor-sharp, identity-verified video just centimeters away from the target through microscopic openings, making it the premier choice for biometric palm-print scanners, starlight financial terminals, and seamless secure kiosks.

Applications & Device Compatibility
Core Application Scenarios
This industrial-grade 4.2mm 3MP ultra-macro pinhole lens is explicitly engineered for point-blank biometric verification, high-security currency tracking, and precision industrial lens data logging. Offering a highly flat 77-degree horizontal perspective with a rare 10cm close-up focus range, it excels as the core optical sensor for non-contact palm-print / iris recognition terminals, advanced vein verification scanners, and smart automated toll counters where authentication occurs immediately adjacent to the lens head. In modern factory automation and machine vision lens setups, its compact 14.5mm form factor allows it to be embedded inside compact laboratory analysis blocks or shallow sorting chutes, tracking delicate close-up mechanical assembly processes or scanning micro-barcodes through small panel drill holes with zero edge distortion.

Frequently Asked Questions
Q: What makes this 4.2mm lens a “macro-capable” pinhole lens?
A: Standard 4.2mm pinhole lenses are tailored for intermediate distances and become heavily blurred when an object gets closer than 30cm. This model features a customized internal lens curve layout specifically optimized for extreme close-ups, allowing it to focus perfectly down to an ultra-short 0.1 meters (10cm). This yields high-contrast macro magnification of barcodes, text, or human palm prints. [1]

Q: Will this 4.2mm lens cause vignetting or dark corners on a 1/2.7″ sensor chip?
A: Not at all. Despite the compact 14.5mm TTL layout, the optical glass elements are highly calibrated to perfectly match the active area of 1/2.7″ image format sensors. It ensures uniform edge-to-edge brightness, crisp relative illumination, and zero corner clipping even at point-blank distances. [1]

Q: What does the “F.O.V.@1/3″ 80°” parameter mean for my device design?
A: This indicates excellent sensor cross-compatibility. If your current hardware uses a 1/2.7″ sensor, you will get a 77° horizontal view. If you choose to swap the sensor module to a smaller 1/3″ chip in the future, the lens will naturally adjust to provide a clean 80° diagonal view without needing any mechanical modification. [1]

Q: Is the focus on this 3MP M12 micro macro pinhole lens adjustable?
A: Yes. It features a manual focus mechanism. By rotating the lens within its thread on the M12 mount board, you can adjust the focus for targets starting from just 0.1 meters away up to infinity, then lock it securely using a standard M12 retaining collar. [1]
