Frequently Asked Questions
-
- Q: What type of filter is integrated into this lens structure?
-
- A: The lens is designed “With filter.” Depending on your ordering requirements, it can be pre-fitted with a standard 650nm IR-cut filter for true-to-life daytime color video, or an IR-pass/dual-band filter for day and night security applications.
-
- Q: How does the field of view differ between 1/2.5″ and 1/3″ sensors?
-
- A: Because a 1/2.5″ sensor has a larger physical surface area, it utilizes more of the lens’s optics, providing a wider 170° diagonal view. On a smaller 1/3″ sensor, the image is slightly cropped, resulting in a 127° diagonal view.
-
- Q: Can this 5MP lens be used on a 2MP (1080P) camera board?
-
- A: Yes, it is fully backward compatible. Mounting a 5 Megapixel optical lens onto a 2MP sensor will enhance edge sharpness, reduce chromatic aberrations, and give you an optically superior image.
-
- Q: Is this a fixed or manual iris lens?
-
- A: This lens has a fixed iris with a large aperture of F1.8. The iris size cannot be adjusted manually or electronically, ensuring a reliably constant flow of light for high-speed imaging.
-
- Q: What is the thread specification for mounting this lens?
-
- A: It features a standard M12x0.5 thread, which is the international standard for board camera optics, often referred to as M12 lenses or S-mount lenses.
-
- Q: What does the T.T.L. measurement represent?
-
- A: T.T.L. stands for Total Track Length, which is 22.76mm for this lens. This is the physical distance from the front tip of the lens to the surface of the image sensor, confirming its ultra-compact profile.
