Product Overview
The LS4056E‑0.05X‑M72 is a high‑performance 40 mm fixed focal length line‑scan industrial lens purpose‑built for 8K 7 μm line‑scan cameras in machine‑vision inline inspection systems.
Featuring M72 lens mount, adjustable F5.6‑F22 aperture, 0.05X magnification, maximum distortion of only 0.15%, and wide working‑distance coverage of 373 mm‑2130 mm. It produces uniform illumination and sharp pixel‑level resolution over the full sensor width, ideal for scanning wide moving materials in printing, film, glass, PCB, textile and flat‑panel industries.
Key Product Features
- Optimized for 8K 7μm high‑resolution line‑scan sensors
Optical design perfectly matches 8K 7 μm line‑scan sensors. It maintains sharp contrast from center to sensor edge, avoids corner softness, and fulfills high‑density pixel sampling requirement for fine‑feature defect detection.
- Low‑distortion optical performance (≤0.15%)
Strict‑controlled distortion minimizes geometric error across the whole field. It guarantees accurate dimensional measurement and true‑to‑life surface reproduction for post‑processing vision algorithms.
- Adjustable iris F5.6‑F22 for depth‑of‑field & lighting flexibility
Continuously adjustable aperture balances light throughput and depth of field. Users can tune exposure for different material reflectivity, suppress over‑exposure on glossy surfaces, and extend usable depth range for uneven samples.
- Wide working‑distance range: 373‑2130 mm
Supports versatile mechanical layout options. Engineers can choose long or short object distance according to machine cabinet space, conveyor height and light source installation requirements.
- Rugged M72 standard industrial mount
Precision‑machined M72 threaded interface fits mainstream 8K line‑scan cameras. Heavy‑duty all‑metal lens housing provides excellent vibration resistance and thermal stability for non‑stop 24‑7 factory operation.
- Uniform full‑field illumination
Well‑corrected vignetting ensures even brightness across entire scanning width. No dark edges on captured images, reducing image pre‑processing workload for vision software.
Core Functions
- High‑speed continuous web surface inspection
Capture high‑quality line‑scan images of continuously moving materials to detect tiny scratches, stains, pinholes, particles, printing offset and coating defects on films, foils, textiles, glass sheets.
- Large‑format flat‑sample defect & dimension detection
Work with 8K line‑scan cameras to complete full‑width scanning of PCBs, flat panels and large‑size plates, implementing defect screening and dimensional measurement in one pass.
- Adapt to varied industrial lighting setups
Compatible with line light sources, coaxial lights and diffuse illumination. Adjustable aperture helps optimize image quality for reflective metal, transparent film, matte textile and other complex surfaces.
- Stable long‑run inline production scanning
Robust mechanical and optical structure resists factory vibration and temperature fluctuation. Maintain consistent imaging quality during long‑time mass‑production inspection without frequent re‑calibration.
- Seamless integration with mainstream vision ecosystems
M72 standard interface works with most brand 8K line‑scan cameras; output images are fully compatible with common machine‑vision software for defect classification, counting and measurement.
