When light enters a prism it is refracted. Each colour of the spectrum is refracted by a different amount and the colours are dispersed ( spread out ) allowing you to see them.

This calculator is applied for calculating the maximum field of view (in length units) that an imaging system can capture under specific conditions using the sensor’s physical size (including horizontal, vertical, and diagonal dimensions), Working Distance (lens end to object end), and Lens EFL (effective focal length of the lens).

Visible light is the part of the electromagnetic spectrum we can see. Each colour has a range of wavelengths. Red has a long wavelength and low frequency and violet has a short wavelength and high frequency.

Visible or white light is made up of a range of colours each with a different wavelength. One way to see the different colours is to use a prism to split the light. When white light enters the prism it slows down and changes direction. The amount the light changes depends on the wavelength. Red light changes direction the least and violet the most.

Note:1. Due to the complexity of the optical system, the following calculated values ​​are approximate and may differ from the actual effect.2. When the size of the object is large enough, you may need a wide-angle lens. The larger the angle, the greater the distortion effect.

The FOV(Field of View) is a measure used in optics and imaging to describe the extent of the observable world that can be seen at any given moment through a lens or optical system. The field of view is typically expressed in degrees and includes HFOV(Horizontal Field of View), VFOV(Vertical Field of View), and DFOV(Diagonal Field of View).

If you need help with the Arducam products you’ve purchased, please include the following questions in your post and answer them to help us better understand your needs.

The field of view is influenced by factors such as the focal length of the lens, the sensor size, and the distance between the lens and the subject. It plays a crucial role in determining how much of the surrounding environment will be visible in the final image or video.

This calculator calculates the minimum FOV required for imaging by using the Working Distance (the distance from the lens to the object) and the actual size of the object (including the Horizontal Size and Vertical Sizes of the object).

White light, which enters the prism, is a mixture of different wavelengths, which get bent ( refracted ) by different amounts though the prism, allowing them to be seen separately.

In the context of cameras and photography, the field of view refers to the area that the camera’s lens can capture in a single frame. A wider field of view captures more of the scene, while a narrower field of view focuses on a smaller portion of the scene. It is an important consideration in choosing lenses and camera systems, as it directly influences what will be included in the photograph or video.

We will calculate the HFOV(horizontal field of view), VFOV(vertical field of view), and DFOV(diagonal field of view) of the imaging system.

Note:1. To accurately calculate the sensor’s physical size, you need to enter the Number of Horizontal Pixels, Number of Vertical Pixels, and Pixel Size (in microns).2. Some ultra-wide-angle lenses own a field of view of more than 180°, in which case the field of view range will be infinite (for example, when the lens focal length is very small and the sensor size is relatively small)3.Due to the complexity of the optical system, the following calculated values ​​are approximate and may differ from the actual effect.
