Frequently Asked Questions

What factors influence accurate camera lens selection?

Key factors include sensor size, working distance, field of view requirements, and the resolution needed for the imaging task. Videology’s lens-focal-length-calculators help quantify these parameters.

How do I choose the correct focal length for industrial imaging?

Use the focal length results generated by our calculators to select a lens that provides the required coverage and image clarity for your industrial environment.

Why is focal length important in embedded systems?

Focal length determines how much of the scene will be captured and how sharp the image will appear. Correct selection improves reliability in inspection, automation, and embedded imaging platforms.

Can lens-focal-length-calculators help reduce development time?

Yes. By providing accurate focal length guidance early in the design process, these calculators help minimize trial-and-error and accelerate integration.

Do I need different focal lengths for various lighting or environmental conditions?

Potentially. Application-specific variables such as lighting, object movement, and contrast levels may influence camera lens selection. The calculators give you a strong starting point for evaluating these needs.
