Frequently Asked Questions
- Q: What makes this M7 miniature lens “low distortion”?
- A: Standard miniature lenses with wide angles often suffer from barrel distortion. This lens utilizes a specialized 4P optical configuration to suppress geometric distortion to under 1%, ensuring straight lines remain perfectly straight in your images.
- Q: Can this lens be used on a 1/3″ sensor?
- A: No, this lens is strictly optimized for a 1/4″ image format. Using it on a larger 1/3″ sensor will cause severe vignetting (dark corners) because the sensor area exceeds the lens’s optical circle.
- Q: Is the focus adjustable, or is it completely fixed?
- A: The lens features a Manual Focus design. While the focal length and zoom are completely fixed, you can fine-tune the focus during installation by threading the lens in or out of your M7 mount holder.
- Q: Does this lens support Day/Night switching or IR-cut filters?
- A: This is a standard megapixel fixed lens. Depending on your project requirements, we can supply this lens with a built-in 650nm IR-cut filter for accurate daylight colors, or an 850nm/940nm pass filter for infrared night vision applications.
- Q: Do you offer customization options for large-volume industrial orders?
- A: Yes, we provide full OEM/ODM services. We can customize the optical coatings, thread parameters, F.O.V., or mechanical housing barrels to suit your specific industrial or medical equipment requirements.
