Selecting the right M12 lens is essential to achieve optimal imaging performance and ensure compatibility with your camera system. Here are the key factors to consider when choosing an M12 lens.
Make sure the lens image circle fully covers the camera sensor to avoid vignetting and ensure clear imaging.
Shorter focal lengths provide a wider field of view (FOV), while longer focal lengths offer a narrower view and more detail at distance.
Use TOWIN's FOV Calculator to estimate the ideal focal length and field of view based on your camera sensor and installation distance.
Go to FOV Calculator →Choose a lens that matches your camera sensor resolution, such as VGA, 2MP, 5MP, 8MP, 12MP, 16MP or 20MP, to ensure sharp and detailed images.
For measurement and inspection applications, low distortion is crucial to maintain geometric accuracy and reliable image analysis.
A proper aperture (F-number) helps control light intake and depth of field, while considering low-light performance ensures clear images in challenging environments.
