75mm F2.8 C-Mount Machine Vision Lens for 1.1-Inch Cameras

75mm F2.8 C-Mount Machine Vision Lens for 1.1-Inch Cameras

The POMEAS PMSVP7520MP is a 75mm fixed focal length machine vision lens designed for industrial imaging systems using 1.1-inch, 1-inch and 2/3-inch sensors. It features a large F2.8 aperture, C-Mount interface, manual focus and manual iris adjustment, making it suitable for industrial inspection, electronics imaging, automation equipment and precision vision applications.

With a focal length of 75mm, this lens is suitable for applications that require a relatively narrow field of view, longer working distance and stable image performance. Its low distortion design helps reduce image deformation in inspection tasks where image consistency is important.

Key Features

• 75mm fixed focal length for machine vision applications
• Large aperture range from F2.8 to F16
• Supports 1.1", 1" and 2/3" industrial camera formats
• Standard C-Mount for easy integration with industrial cameras
• Manual focus and manual iris adjustment
• Minimum focus distance from 0.5m to infinity
• Low distortion: <0.15% for 1.1"/1" formats and <0.1% for 2/3"
• Suitable for machine vision inspection, electronics inspection, automation equipment and precision measurement support imaging

Why Choose a 75mm F2.8 Machine Vision Lens

Compared with shorter focal length lenses, a 75mm industrial lens is more suitable when you need a narrower field of view or a longer installation distance between the camera and the object. It helps concentrate more image pixels on the target area and is commonly used in visual inspection, part positioning and industrial imaging systems.

The F2.8 large aperture is also helpful when brighter imaging is needed or when the lighting environment is limited. At the same time, the adjustable iris allows users to balance brightness, sharpness and depth of field according to the actual application.

Compatible Cameras and Sensor Formats

The PMSVP7520MP is designed for industrial cameras using a C-Mount interface and supports up to 1.1-inch sensor format. It is also suitable for 1-inch and 2/3-inch cameras.

If your system uses a smaller sensor, the field of view will become narrower at the same working distance. If your system uses a camera larger than 1.1", please confirm the optical coverage before selection.

Difference from a Standard 2/3-Inch 75mm C-Mount Lens

Compared with a conventional 75mm lens designed only for 2/3-inch cameras, the PMSVP7520MP supports larger image formats up to 1.1". This makes it more suitable for customers who need a larger sensor format, more flexible camera matching or a wider usable imaging area.

Typical Applications

• Machine vision inspection
• Electronics inspection
• PCB inspection
• Automation equipment
• Precision measurement support imaging
• Assembly line visual positioning
• Industrial image acquisition
• Long working distance inspection systems

When This Lens May Not Be Suitable

• Applications that require continuous zoom or changing field of view
• Very short working distance imaging below 0.5m
• High-precision dimensional measurement where telecentric optics are required
• Projects requiring motorized focus or motorized iris control
• Systems using camera sensors larger than 1.1" without optical coverage verification

If your project is focused on dimension measurement rather than general imaging, you may also consider a telecentric solution such as this C-Mount telecentric lens for machine vision measurement.

Frequently Asked Questions

1. Is PMSVP7520MP suitable for a 1.1-inch camera?

Yes. This lens is designed to support sensor formats up to 1.1", and it is also compatible with 1" and 2/3" industrial cameras using a C-Mount interface.

2. What is the aperture range of this lens?

The aperture range is F2.8-F16. It supports manual iris adjustment, allowing users to balance brightness and depth of field based on the application.

3. What is the minimum focus distance?

The minimum focus distance is 0.5m, and the lens supports focusing to infinity.

4. Can this lens be used for measurement applications?

It can be used for general industrial imaging and inspection support. However, if your application requires very high dimensional accuracy and stable magnification against height variation, a telecentric lens is usually a better choice.

5. How do I choose whether this 75mm lens fits my project?

Please provide your camera model, sensor format, working distance, required field of view and inspection target size. POMEAS can help evaluate whether PMSVP7520MP is the right option.
