# sensorVerticalAperture

The height, in millimeters, of the camera’s simulated imaging surface.

## Declaration

```swift
var sensorVerticalAperture: Float { get set }
```

## Discussion

Discussion In a physically based camera, field of view is based on the focal length of the lens and the vertical aperture of the imaging surface (film or sensor). Changing the focalLength or sensorVerticalAperture property updates the fieldOfView property to the corresponding value, and vice versa. To determine the width of the imaging surface, use this property and the sensorAspect property. For example, with the default vertical aperture of 24mm and default aspect ratio of 1.5 (or 3:2), the horizontal aperture is 36mm.
