Description
Introducing our professional-grade 4mm F1.8 2MP CS-mount IR-corrected pinhole lens, masterfully engineered for 24/7 day/night covert surveillance and precision testing through thick panels or safety walls. Departing from unstable macro optics, this high-durability long-barrel needle pinhole lens features a standard CS mount and factory-integrated IR-correction technology. Boasting a super-bright F1.8 large aperture and a perfectly calibrated Manual Iris system, this fixed focal lens completely eliminates focus shifts under infrared lighting, making it the premier choice for professional box cameras in high-security vaults, research laboratories, and fixed-illumination hidden matrix systems.
Product Highlights
- IR-Corrected Day/Night Co-Focusing: Features advanced IR-correction coatings that completely eliminate focus blur when shifting from daytime visible light to 850nm/940nm invisible infrared night-vision setups.
- 90.5mm Wall-Penetrating Tube: Built with a specialized 90.5mm TTL elongated barrel, enabling the micro optical tip to pass directly through heavy armor plates or double-layered partitions for discrete hidden surveillance.
- Ultra-Precise Manual Iris Lock: Equipped with a highly stable Manual Iris mechanism, allowing engineers to lock the massive F1.8 aperture at precise light thresholds to ensure bulletproof imaging reliability under constant glare.
- Rugged Heavy-Duty CS Mount: Eliminates the fragile thread tolerance of micro board optics by adapting directly with professional CS-mount box cameras for long-term vibration resistance.

Applications & Device Compatibility
Core Application Scenarios
This industrial-grade 4mm IR-corrected pinhole lens is custom-designed for 24/7 darkroom environments, laboratory monitoring cabinets, and specialized industrial lens sensing. Thanks to its unique 90.5mm elongated needle structure, it functions as the premier optical layout for high-security banking vaults, armored cash-transport compartments, and military perimeter hideaways where the box camera must sit safely behind reinforced barriers. Featuring an ultra-short 0.15m M.O.D. and a highly stable lockable manual iris, it excels inside sealed scientific testing chambers or clean-room pharmaceutical assembly lines. The lens can pierce thick insulation walls to track moving parts or scan barcodes under intense daytime illumination or invisible nighttime infrared lasers, providing pristine 2MP data without thermal drift or pixel blurring.
Compatible Device List
- Fully compatible with standard 1/3-inch and 1/4-inch CMOS box cameras with standard CS-mount interfaces (such as Sony STARVIS, Panasonic, or specialized scientific imaging blocks).
- Directly compatible with multi-wavelength infrared illuminators (optimized for 850nm and 940nm undercover arrays).
- Ideal for integration into custom machine vision lens enclosures, tactical enforcement gear plates, and laboratory vacuum cell bulkheads.
- Supports tailored internal glass configurations to filter out specific ultraviolet (UV) rays based on client hardware requirements.
Frequently Asked Questions
Q: What is the benefit of an “IR-Corrected” pinhole lens?
A: Standard pinholes blur under night vision. This lens features IR-Correction elements, ensuring visible and infrared light focus on the exact same plane for crystal-clear 1080P images 24/7.

Q: Why choose a Manual Iris over a DC Auto-Iris?
A: Manual Iris eliminates motorized parts. It allows you to lock the F1.8 aperture mechanically, providing zero configuration drift in environments with constant light or magnetic interference.

Q: How does the 90.5mm TTL help with installation?
A: The elongated tube easily pierces thick wall brackets or panels. Being 10mm shorter than standard 100mm designs, it saves rear clearance inside tight camera enclosures.

Q: Can this long needle lens be used for close-up scanning?
A: Yes. Despite its long barrel, it has a short 0.15m M.O.D., letting you position the tip close to test tubes or micro components with zero wide-angle distortion.
