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.
