Hyuduo 16K 60mm F4 Manual Line Scan Lens
The Hyuduo lens is designed for line scan systems requiring extreme detail at a 60mm focal length. It supports 16K imaging with a fixed F4 aperture, offering high light transmission for bright, high-contrast captures. This setup is best for inspectors needing precise edge definition in features such as micro-components or surface defects. The lens uses an aviation-grade aluminum housing for durability in industrial environments.
- Best for high-resolution line scans where 16K output is essential.
- Better for controlled lighting conditions to maximize contrast.
- Choose this if you require a robust, fixed-aperture solution with long service life.
Caution: The fixed aperture means limited exposure flexibility; ensure lighting is optimized for your downstream sensors.
12K Line Scan Lens (0.75X) For 12K/16K Systems
This lens supports high-resolution imaging for 12K configurations and offers compatibility across 16K workflows. With a 0.75X magnification, it balances field of view with detail, making it suitable for medium-sized parts and assembly lines. Its focal length of 116mm provides flexible mounting options for longer scanning distances.
- Best for mid-scale parts inspection where detail at 12K is required.
- Better for installations needing a balance between coverage and resolution.
- Avoid if you need a very wide field of view above 60mm working distance.
Limitation: Larger lens size may necessitate careful mounting alignment in tight fixtures.
Low Magnification Line Scan Lens 8K (0.08X, 35mm)
Designed for broad scenes where subject detail exists across a wide area, this lens provides an 8K imaging path with low magnification. With focal length in the 20–90mm range and 0.0358–0.1× magnification, it supports fast scanning of large panels or conveyor lines. It’s a practical choice for QA stations that must monitor long runs of product.
- Best for wide-area scanning with acceptable detail.
- Better for systems prioritizing throughput over tiny feature resolution.
- Choose this if your line scan needs cover larger products or long strips.
Limitation: Lower magnification may reduce the ability to resolve very small defects without higher lighting or higher-resolution sensors.
Dioche 16K High Resolution Line Scan Lens
The Dioche lens is built from aviation-grade aluminum with a focus on stable mounting and precise focus control. Its 60mm length and 16K capability suit high-accuracy inspection roles in harsh environments. It emphasizes eliminating shading and vignetting to deliver a clean, consistent field of view across the scanned area.
- Best for applications demanding hard-walled construction and consistent framing.
- Better for setups where precise manual focusing and stable aperture control are needed.
- Avoid if you require automatic focus or motorized aperture control.
Note: The manual focus and aperture requirements mean setup time may be longer than motorized systems.
ZJchao 16K 3.5μm 60mm Lens
This lens targets line array sensors with a 3.5μm pixel size and a 60mm focal length, delivering crisp line-scan imagery at 16K resolution. Its aluminum alloy housing supports durability in factory settings while maintaining tight tolerances for alignment. The design focuses on minimizing distortion and maximizing pixel-level detail.
- Best for ultra-fine detail when using line array sensors with small pixel pitch.
- Better for long-term deployments where stability matters.
- Avoid if your camera system cannot support 16K data throughput.
Limitation: Data bandwidth and processing requirements increase with 16K outputs, which may influence downstream hardware needs.
Buying Guide: Making the Right Line Scan Lens Choice
What should you consider when selecting a line scan lens?
- Resolution needs: Higher line counts (12K–16K) demand compatible sensors and data processing; match lens capability to your camera and system.
- Focal length and field of view: Longer focal lengths narrow the field of view; shorter lengths widen it. Choose based on part size and scanner distance.
- Aperture and light transmission: Fixed apertures improve brightness and contrast in busy scenes but reduce exposure flexibility. Consider lighting design to complement the lens.
- Build quality and mounting: Aviation-grade aluminum housings offer durability in harsh environments. Ensure mounts and seals fit your machine’s chassis.
- Manual vs. motorized control: Manual focus/aperture work well in stable setups; motorized adjustments suit automated lines and frequent recalibration.
- Compatibility: Verify sensor type (line scan vs area scan), pixel pitch, and driver support. Some lenses target specific line array configurations.
What questions should you ask before buying?
- Will the lens align with my existing line scan camera’s focal length requirements?
- Is the lighting environment sufficient for the lens’s aperture and resolution?
- Do I need a rugged housing for continuous operation in manufacturing?
- Is manual adjustment acceptable, or is automation preferred for my line?

Frequently Asked Questions
- What is line scan imaging best suited for?
Line scan excels at surfaces with uniform texture where high throughput and edge clarity are essential, such as conveyor inspections. - Why choose a 60mm lens for line scan?
A 60mm focal length often provides a good balance between working distance, field of view, and resolution for many industrial setups. - Do these lenses require special lighting?
Yes. Bright, even illumination minimizes shading and maximizes contrast, particularly at higher resolutions like 16K. - Is manual focus common in line scan lenses?
Many line scan lenses offer manual focus for stable, repeatable setups, though some lines use motorized focus for automation. - What should I check before purchasing?
Ensure sensor compatibility, mounting compatibility, and whether the system supports the lens’s resolution and data rate. - Can I upgrade later?
Upgrading to higher resolution lenses often requires compatible line scan cameras and data handling capabilities; plan for future-proofing data processing.
