| Lens Mount | C-mount is widely used for machine-vision cameras; CS-mount is used where a shorter flange distance is required. | Confirm camera interface, flange focal distance, mechanical clearance, and locking provisions. | Factory inspection, robotics, barcode reading |
| Sensor Format | Lens image circles are commonly matched to 1/3-inch, 1/2-inch, 2/3-inch, 1-inch, and larger sensors. | The image circle should fully cover the sensor to avoid vignetting and loss of usable pixels. | Area-scan and compact smart-camera systems |
| Focal-Length Range | Fixed focal lengths commonly range from wide-angle lenses below 12 mm to telephoto lenses above 50 mm. | Select according to working distance, field of view, sensor size, and available installation space. | Conveyor inspection, dimensional measurement, distant target imaging |
| Resolution Support | Industrial lenses are specified for compatibility with sensor pixel sizes and required image detail. | Check modulation transfer performance, corner sharpness, and chromatic aberration at the operating wavelength. | Defect detection, OCR, semiconductor and electronics inspection |
| Aperture Control | Manual, fixed, or motorized iris configurations are commonly available. | A smaller aperture generally increases depth of field but reduces light transmission and may introduce diffraction. | Variable-height parts, pick-and-place systems, inspection cells |
| Depth of Field | Required depth of field depends on object height variation, working distance, aperture, and acceptable blur. | Telecentric designs are preferred when dimensional consistency and minimal perspective error are critical. | Metrology, gauging, precision assembly |
| Telecentricity | Object-space telecentric lenses keep magnification relatively constant across changes in object distance within the specified range. | Evaluate telecentricity error, working distance, field size, and lighting geometry together. | Dimensional inspection and high-accuracy measurement |
| Optical Coating | Multilayer anti-reflection coatings are used to improve transmission and reduce flare over defined wavelength bands. | Match coating performance to visible, near-infrared, ultraviolet, or multispectral illumination. | Machine vision, laser alignment, spectral imaging |
| Mechanical Durability | Production environments may require vibration resistance, secure focus and iris mechanisms, and robust housings. | Review operating temperature, shock and vibration limits, ingress protection, and mounting stability. | Automotive lines, packaging machinery, outdoor or dusty installations |
| Lighting Compatibility | Lens choice must account for coaxial, ring, bar, dome, backlight, or structured-light illumination. | Assess flare, ghosting, reflection control, polarization requirements, and available illumination angle. | Surface inspection, contrast enhancement, dimensional gauging |
| Supply and Integration | Industrial buyers typically require dimensional drawings, optical data, samples, replacement availability, and integration support. | Compare documentation quality, customization capability, lead-time reliability, and lifecycle support. | OEM equipment, system integrators, high-volume production |
