OEM ZOOM-LENS-18-10812.5 – Industrial C-mount zoom lens for machine vision and surveillance tasks

From my experience, the model code “ZOOM-LENS-18-10812.5” points to a versatile 18–108 mm zoom range with a fast F2.5-class aperture, designed for C‑mount machine vision and security cameras. You might notice that this range comfortably covers medium to long working distances on inspection lines, packaging stations, and fixed traffic cameras, so you can fine‑tune field of view without swapping lenses. One thing I appreciate is the typical lockable mechanics—focus and iris hold steady even under vibration, which matters a lot in production environments.

Key Features

• 18–108 mm zoom range – A practical 6× range that covers close inspection to longer stand‑off views without changing optics.
• Fast aperture around F2.5 – Typically bright enough for low‑light production lines and night‑time surveillance.
• C‑mount compatibility – Works with common machine vision and CCTV cameras; easy to integrate with standard mounts and accessories.
• Industrial mechanics – Manual zoom/focus with lock screws in many cases; helps resist drift from shock and vibration.
• Support for typical 1/2″–2/3″ sensors – A sensible pairing for 3–5 MP cameras used on conveyors, robotics, and ITS.
• Back-focus adjustment – Dial in parfocal performance so focus stays consistent while zooming, which reduces operator fiddling.
• Accessory-friendly – Compatible with common C‑to‑CS spacers, lens holders, and IR‑cut/ND filters (threaded front rings are typical).

Technical Specifications

Application Fields

This lens fits right into machine vision inspection, packaging QA, pick‑and‑place verification, ITS/traffic monitoring, perimeter security, and lab imaging. On fast‑changeover lines, the 18–108 mm span lets technicians reframe for different carton widths in seconds. A logistics customer mentioned they replaced two fixed focal lengths with this single zoom to simplify maintenance on a barcode tunnel—seems to be a smart move when product sizes vary day to day.

Advantages & Value

• Flexibility – One lens covers multiple stations and working distances, reducing spares inventory.
• Compatibility – C‑mount and 1/2″–2/3″ sensor pairing aligns with most mainstream machine vision cameras.
• Reliability – Lockable rings and stable mechanics typically hold calibration through shifts and minor vibration.
• Cost control – Fewer lens changes means less downtime and fewer calibration cycles.
• Support – We can help with lens‑to‑sensor matching, field of view calculations, and accessory selection.

Installation & Maintenance

• Mounting – Install on a C‑mount camera inside a DIN‑standard cabinet or rigid bracket; avoid flex in the lens holder.
• Ventilation – Provide airflow to match the host camera’s thermal limits; avoid condensation across temperature swings.
• Wiring – If using a motorized version, route 12 VDC control leads separately from high‑noise power lines.
• Back‑focus & parfocal setup – Warm up the camera, set focus at tele end, then adjust back‑focus so image stays sharp through the zoom range.
• Cleaning – Use a blower first, then lens tissue with isopropyl alcohol; avoid contact with coatings using rough swabs.
• Routine checks – Inspect and re‑tighten lock screws quarterly; re‑verify focus after any mechanical shock or camera change.

Quality & Certifications

• RoHS compliant in most cases for optical assemblies
• CE marking where applicable for associated motorized components
• Manufacturing quality – typically produced under ISO 9001 processes
• Warranty – 365 days standard coverage

If you’re deciding between this and a fixed‑focal alternative, we can run a quick FOV and working distance check against your sensor size and target dimension. In many cases, ZOOM-LENS-18-10812.5 ends up being the safer choice when product variants or camera placements change over time.
