Modern video surveillance no longer relies on standard, catalog-bought optics. High-resolution edge AI, non-standard sensor formats (such as 1/1.8" and 1/1.7"), and harsh operating environments demand application-specific lens assemblies. Selecting the right optical engineering partner defines your camera system's imaging performance.
If your project requires tight optical tolerances, wide-temperature stability, or unique mechanical housing, you need a qualified manufacturing partner. Jinyuan Optics delivers precision-engineered, custom optical solutions directly to system integrators and camera OEMs worldwide.

Engineering Trends Driving Custom Optics in 2026
Surveillance systems have evolved beyond basic video capture. Network cameras now execute real-time neural network inference, automated license plate recognition (ALPR), and low-light facial tracking. These advanced workloads expose the limitations of off-the-shelf lenses.
Several technical factors make custom design mandatory for modern camera systems:
- Large-Format Sensor Integration: Edge-AI processors require high signal-to-noise ratios, pushing sensor sizes from classic 1/3" formats to 1/2", 1/1.8", and 1/1.7" chips. Standard S-mount optics often vignette on these large image circles without tailored optical configurations.
- True Day/Night Athermalization: Shifting ambient temperatures (-40°C to +85°C) warp mechanical barrels and alter optical glass refractive indices. Uncompensated optics lose focal plane alignment, degrading automated analytics.
- Dual-Band Parfocal Performance: Surveillance systems rely heavily on 850nm and 940nm active infrared illumination. Poor chromatic aberration correction causes substantial focus shift between daytime visible spectra and nighttime IR capture.
Evaluation Criteria: How to Select an Optical Partner
Selecting an optical vendor requires rigorous auditing of their manufacturing and testing processes. Commercial procurement teams and optical systems engineers should evaluate every prospective security application lens manufacturer across four critical criteria:
1. In-House R&D and Optical Simulation
Top-tier manufacturers do not outsource lens design. They run proprietary Zemax or Code V simulations to optimize surface curvatures, reduce lens element count, and maximize relative illumination. A capable vendor validates optical prototypes rapidly using precision diamond-turning or rapid tooling before initiating mass glass molding.
2. Quality Control and Environmental Testing
Manufacturing precision optics requires rigorous production control. Facilities should hold ISO 9001 certification and operate Class 10,000 or Class 1,000 cleanrooms. Look for automated verification testing against the Modulation Transfer Function (MTF) and full compliance with optical drawing standards, such as ISO 10110.
3. Athermal Mechanics and Material Selection
A resilient security lens must combine optical elements with balanced thermal expansion coefficients (CTE). Vendors should offer metal barrels (brass, aluminum) or specialized polycarbonates paired with specific crown and flint glasses to hold back focal length (BFL) across demanding thermal profiles.
4. Customization and OEM Scalability
A reliable supplier must handle both small-batch pilot builds and volume manufacturing. Whether modifying an M12 thread pitch, applying anti-reflective (AR) coatings for targeted wavelengths, or developing an IP67-sealed housing, your manufacturer must adapt to your mechanical envelope.

Primary Applications: Smart city surveillance, commercial building access control, dome network cameras.
3. 1/1.7-inch S Mount 12MP 3.2mm Security Camera Lens
High-resolution AI recognition systems require large-format sensors to gather sufficient light without introducing electronic noise. This 12MP lens covers up to 1/1.7-inch image circles. Despite its wide 3.2mm focal length, it controls barrel distortion and preserves edge-to-edge sharpness for algorithmic processing.
Primary Applications: AI facial recognition terminals, wide-area public square monitoring, UAV search-and-rescue cameras.
4. 1/1.7-inch S Mount 12MP 5mm Security Camera Lens
Balancing wide-area situational awareness with targeted pixel density, this 5mm lens extracts maximum detail from 12MP sensors. The optical design optimizes light transmission, making it ideal for starlight sensor architectures that capture high-speed motion in poor lighting.
Primary Applications: Automatic License Plate Recognition (ALPR/ANPR), traffic flow analysis, border checkpoint inspection.
5. 1/2” High Resolution Low Distortion Board Mount Lens
Standard security lenses frequently exhibit optical barrel distortion between 15% and 30%. This assembly reduces optical distortion to under 1.5% through precision glass element profiling. It bridges the gap between wide-angle security surveillance and industrial machine vision.
Primary Applications: Factory floor security combined with visual inspection, logistics tracking, LiDAR-visual fusion systems.
Technical Guide: How to Specify a Custom Security Lens
When requesting engineering quotations or starting a custom optical design cycle, your hardware team should provide a complete technical specification package.
Sensor Format and Image Circle Matching
Lenses are designed for a maximum image diagonal. Placing a lens built for a 1/3" sensor onto a 1/2" or 1/1.7" sensor causes severe optical vignetting and black borders. Always define your active sensor array dimensions, pixel pitch (e.g., 2.0µm, 1.4µm), and target chief ray angle (CRA) so the optical vendor can match sensor micro-lens acceptance angles.
IR Chromatic Correction (Day/Night Parfocal)
Standard glass exhibits distinct refractive indices for visible light (400-700nm) and near-infrared light (850-940nm). Without specialized low-dispersion crown glass, your system will blur when the mechanical IR-cut filter switches out at night. Specify whether your deployment uses 850nm or 940nm illuminators to ensure the designer controls chromatic aberration across that exact bandwidth.
Thermal Drift and Environmental Sealing
Outdoor surveillance enclosures experience severe thermal shifts. Optical materials expand and contract, causing the focal point to drift away from the sensor surface. Ask your manufacturer for an optical athermalization report, and specify environmental protection levels (such as IP67 front element sealing or anti-fog hydrophobic coatings) up front.
Frequently Asked Questions
Q1: What are the typical lead times and NRE costs for a custom
surveillance lens build?
A1: Non-Recurring Engineering (NRE) costs
vary based on optical complexity, element counts, and barrel tooling
requirements. Prototyping typically takes 4 to 8 weeks, covering optical design,
tooling fabrication, sample polishing, and cleanroom assembly. Production
scaling follows verification testing within 6 to 10 weeks.
Q2: Why does an IR-corrected surveillance lens matter if our cameras
use edge AI autofocus?
A2: Fixed-focus board cameras cannot adjust
focal depth mechanically. If the lens lacks true optical Day/Night parfocal
correction, the focus shifts noticeably under infrared light. This optical blur
degrades AI identification confidence, particularly for license plate capture
and facial recognition.
Q3: How does an M12 (S-mount) lens differ from a C or CS-mount
lens?
A3: M12 (S-mount) lenses use a compact M12x0.5mm thread
directly integrated onto the sensor PCB, offering a small footprint and high
vibration resistance for embedded systems. C and CS-mount lenses use larger
1-inch threaded barrels with specific flange focal distances (17.526mm for
C-mount, 12.526mm for CS-mount), commonly used on larger standalone box
cameras.
Q4: Can Jinyuan Optics manufacture custom lenses in low production
volumes?
A4: Yes. Jinyuan supports rapid engineering verification
through low-volume prototype builds. Once your design passes testing and
integration validation, our ISO-certified facilities scale seamlessly to
high-volume commercial production.
Q5: What metrics quantify optical distortion in security
lenses?
A5: Optical distortion is typically measured as TV
distortion or radial distortion (percentage displacement from the theoretical
point). Standard fisheye or ultra-wide lenses may exhibit -20% or more barrel
distortion, whereas precision low-distortion lenses reduce this below -1.5% to
preserve geometric accuracy for AI recognition models.
