카메라 화각을 어떻게 계산하나요?
Camera angle of view (AOV) describes the angular extent of a scene visible through the lens. The calculation uses the arctangent function relating object size to viewing distance. Define what the camera must see, then select optics accordingly.
The visualizer above shows this geometry in real-time. As you change inputs, the angle between the camera and object edges updates, demonstrating how FOV changes with object size and distance.
센서 사양을 바탕으로 초점 거리를 어떻게 계산하나요?
Once you know your target FOV, calculate the required lens focal length from your sensor's pixel dimensions. First compute sensor size from pixel count and pitch, then apply the inverse FOV formula.

After calculating your required focal length, browse our M12 lens collection to find matching options. We stock 70+ M12 lens models from 0.8mm fisheye to 100mm telephoto, and most ship same-day from US inventory when ordered before 12 PM PST.
AOV와 선형 시야각(FOV)의 차이점은 무엇인가요?
Angle of view is measured in degrees. For a lens focused at or near infinity, AOV is set by focal length and sensor size and does not change with subject distance; at close focus the effective AOV narrows slightly. Linear FOV describes actual scene coverage (meters or feet) at a specific working distance.
Convert between them using: Linear FOV = 2 × distance × tan(AOV/2). A 60° horizontal AOV covers 1.15 meters wide at 1 meter distance, or 11.5 meters at 10 meters.
렌즈 왜곡은 시야각(FOV)에 어떤 영향을 미치나요?
These calculations assume ideal rectilinear projection. Real wide-angle lenses exhibit barrel distortion, capturing more angular content at edges than predicted. Fisheye lenses use entirely different projection models.
For applications requiring precise FOV specification with distortion, use our distortion-aware FOV calculator or consult manufacturer datasheets.

Inspection systems: Define inspection width and mounting height, calculate HFOV, select lens. Our C-mount lenses suit industrial inspection with global shutter sensors.
Robotics navigation: Wide-angle coverage (120°+) provides situational awareness. Our fisheye M12 lenses reach 185° diagonal FOV for panoramic perception.
