Description
Introducing our high-performance 3.7mm F2.5 M12 ultra-macro MOD pinhole lens, the ultimate optical engineering solution for high-precision, close-up covert surveillance and industrial embedded networks. Shattering standard optical boundaries, this specialized macro pinhole board lens is capable of micro-focusing at an exceptional 0.1m minimum object distance (M.O.D.). Paired with a record-shattering 10.5mm Total Track Length (TTL) and a micro-head conical silhouette, it shoots razor-sharp, zero-distortion megapixel video just centimeters away from a target through microscopic openings, making it the premier choice for biometric palm-print scanners, high-security medical analyzers, and discrete automated machinery.
Product Highlights
- Extreme 10cm Ultra-Macro Focus: Features an upgraded M.O.D. of 0.1 meters, enabling the hidden camera to capture crisp, magnified images of text, codes, and human biometrics at point-blank range.
- Ultimate 10.5mm Short TTL: The most compressed axial profile in its class, resolving severe mechanical spacing conflicts inside shallow metallic enclosures, slim kiosks, and thin faceplates.
- Low-Distortion 70° Proportional Frame: The calibrated 70° horizontal F.O.V. drastically suppresses aggressive corner bending, providing linear, undistorted images optimized for AI identification and scanning software.
- Micro-Cone Needle Silhouette: Built with a highly tapered conical front tip, ensuring the heavy optical body remains entirely hidden behind the panel plane for flawless hidden surveillance.

Applications & Device Compatibility
Core Application Scenarios
This industrial-grade 3.7mm ultra-macro MOD pinhole lens is explicitly engineered for point-blank biometric verification, high-security currency tracking, and precision industrial lens data logging. Offering a natural 70-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 blood-vessel scanners, and smart reverse vending machines where verification occurs immediately adjacent to the lens head. In modern factory automation and machine vision lens setups, its flat 10.5mm form factor allows it to be embedded inside compact laboratory analysis blocks, microfluidic testing wells, or shallow sorting chutes, tracking delicate close-up chemical changes or microscopic product flaws through tiny panel drill holes.
Compatible Device List
- Perfectly optimized for high-sensitivity 1/3-inch CMOS image sensors (including Sony, OmniVision, and SmartSens series).
- Direct fit for ultra-short M12 hidden camera modules, close-range scanning IPC board assemblies, and Tuya-powered smart smart-home devices.
- Ideal for integration into custom industrial machine vision enclosures, medical diagnostics terminals, and secure document verification instruments.
- Fully supports factory customization for dual-band pass filters (650nm IR cut / 850nm / 940nm IR pass) to facilitate true invisible infrared nighttime illumination.
“Designed for extreme close-up macro terminal security and micro pinhole inspection applications.”
Frequently Asked Questions
Q: What makes this 3.7mm macro pinhole lens different from your 0.2m or 0.3m 3.7mm pinhole lenses?
A: This model features a customized internal lens curve layout specifically optimized for extreme close-ups. While standard 3.7mm lenses become heavily blurred when an object is closer than 20cm or 30cm, this model can focus perfectly down to an ultra-short 0.1 meters (10cm), allowing for high-contrast macro magnification of barcodes, text, or human palm prints.

Q: Does the ultra-short 10.5mm TTL cause dark corners (vignetting) when shooting at 10cm?
A: Not at all. Despite its hyper-compressed physical profile, the optical circle is meticulously calibrated to fully cover the active area of 1/3″ image format sensors, ensuring uniform edge-to-edge brightness and maximum relative illumination even at point-blank distances.

Q: Why is the 10.5mm TTL critical for hardware product developers?
A: In micro medical terminals and compact biometric keypads, every millimeter of depth matters. A 10.5mm TTL ensures that your engineering team can drastically reduce the thickness of the overall device housing, keeping the camera sensor module entirely flush with the cover plate.

Q: Is the focus on this micro M12 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 an M12 retaining collar.
