20MP 1.1″ 35mm f/2.8 Manual Iris Lens — Industrial
Best for high-resolution machine vision tasks requiring sharp detail and low distortion. This HTENG VISHI lens supports a 1″ image size and offers manual iris and focus control for precise exposure and focus tuning. The device is well-suited for automated inspection lines where pixel-level clarity matters, such as print defect detection or tiny feature recognition. Choose this if you need large image resolution with consistent distortion control.
Best for: high-resolution imaging workflows, automation lines that demand precise control over depth of field and focus. Caution: manual controls require operator input for each setup change.
FA 16mm Machine Vision Lens — 1/1.8″
Designed for industrial automation, this wider-angle lens provides an expansive field of view with HD 5MP performance and distortion under 1%. The 1/1.8″ image size matches common machine vision cameras, making it a solid choice for line-scan or assembly inspection where broader coverage is essential. Best for: systems needing a larger capture area without sacrificing detail. Caution: distortion metrics are vendor-supplied; verify in your setup if ultra-wide edges matter.
FA 12mm Machine Vision Lens — 1/1.8″
Best for balanced detail and working distance in tight spaces. This fixed-focus 12 mm lens provides HD 5MP capability with distortion under 1% and is compatible with 1/1.8″ image sizes. It is a practical option for close-up inspections where a mid-range focal length is optimal. Caution: fixed focus may require re-focusing if scene depth changes dramatically.
FA 4mm Machine Vision Lens — 1/1.8″
Best for close-up inspection tasks where space is limited. The 4 mm focal length offers a tight field of view and HD 5MP imaging with distortion under 1%. Suitable for high-magnification tasks on small components. Caution: extremely short focal length can magnify perspective errors if the object is not adequately positioned.
12MP 12mm Lens — 1/1.7″ C Mount
Best for high-resolution applications where a longer focal length is needed without sacrificing detail. The 12 MP design targets high-resolution cameras up to 12 megapixels, with anti-reflective coatings to enhance contrast. This lens is a good pick for long-range inspection, barcode reading, or flat-surface defect detection. Choose this if you need both high resolution and a moderate telephoto reach. Caution: longer focal length reduces depth of field; ensure stable subject distance.
100X Microscope Lens for Raspberry Pi — C/CS-Mount
Best for micro-scale inspection and educational setups. This 100X lens uses C/CS-Mount and is compatible with Raspberry Pi HQ Camera. It provides high magnification for tiny features and is well-suited for electronics work, PCB inspection, or micro-assembly checks. Best for: projects needing close-up magnification with affordable hardware. Caution: extreme magnification reduces field of view and requires precise alignment and lighting.
Buying Guide
What focal length do you need? Short focal lengths (like 4–8 mm) are ideal for close-up work in tight spaces, while mid-range (12–16 mm) suits general-purpose machine vision. Longer focal lengths (8–12 mm) provide more distance between camera and target with increased depth of field under certain conditions.
Which sensor size matters? Lenses advertised for 1″ or 1/1.8″ sensors align with common industrial cameras; ensure your camera’s image circle matches or exceeds the sensor size to avoid vignetting or corner blur.
Do you need autofocus or fixed focus? Fixed-focus lenses are simpler and often more rugged for production lines, while manual iris and focus control lets you optimize exposure and depth of field for varying lighting.
Distortion and image quality: Check distortion specs (under 1% is typical for high-quality machine-vision lenses) and consider coatings that improve contrast in challenging lighting. High-resolution lenses benefit from anti-reflective coatings and glass composites for sharpness.
Mount compatibility and installability: Confirm C-mount compatibility with your camera and whether adapters are necessary (CS or C-mount). Some lenses come with suitable mounting hardware but may require additional spacers or adapters for optimal focus at your working distance.
FAQ
- What is a C-mount lens used for? It is designed for cameras with a 1-inch to 1/1.8-inch image sensor used in machine vision, industrial cameras, and CCTV systems.
- Why choose a fixed-focus lens? For durability and repeatable performance on production lines where subjects are at a consistent distance.
- How does focal length affect depth of field? Short focal lengths yield a larger depth of field at the same aperture, while longer focal lengths narrow the depth of field, requiring precise subject distance.
- Are higher megapixel lenses necessary for all applications? Not always; high-MP lenses are beneficial when you need detailed imagery from high-resolution cameras, but matching the lens to the camera and lighting is key.
- Can I use these lenses with Raspberry Pi? The 100X microscope lens is designed for Raspberry Pi HQ Camera with C/CS-mount adapters; verify compatibility with your specific Pi setup.
- What should I verify before buying? Sensor size compatibility, focal length, distortion specs, and whether the lens supports the required mounting and thread standards for your camera.
