Single spherical ball lenses may be used for laser collimation or focusing. Two lenses may be used to enable laser-to-fiber coupling, fiber-to-fiber coupling, or fiber-to-detector coupling. Different diameter spheres may be mixed to produce magnification.

Spherical ball lenses are commonly used for laser collimating and focusing. 1, 2, 3, and 5 mm diameters are available. Larger spheres are easier to handle and ease the sensitivity of translational alignment. However, smaller spheres fit into smaller packages.

When we say 16:9 resolutions, we actually are talking about widescreen resolutions at 16:9 aspect ratio. 16:9 resolution is now the most popular among all. It is the standard aspect ratio for HDTV. Cameras like GoPro, DJI, iPhone set 16:9 resolutions as default, although social media sites like Instagram prefer 1:1. So what are the true 16:9 resolutions?

How to tell if it is true 16:9 resolution? There is a simple way. Divide the width number of resolution by 16. And you should get the greatest common factor. If the height number is divisible by the greatest common factor and the result is 9, then it is a true 16:9 resolution.

When the ratio is fixed, you can easily calculate how many pixels are in width and height for various types of videos. Take 4K 16:9 videos as an example. The resolutions can be 3840 x 2160, 3968 x 2332, 4096 x 2304, and 4224 x 2376.

To prevent distortion, do not make pixels exceed either side of the source video frame. For example, if your source video is 1080 x 1080 at 1:1 and you set it to 1920 x 1080 at 16:9, then the result will be expanded. In such case, 1080 x 720 is the best option for you.

When we talk about resolutions, we mean the total number of pixels of an image, expressed as A x B. While 16:9 is the ratio of the width (in pixels) of an image to its height. So accurately speaking, 16:9 resolutions are resolutions that can be used for videos/images at the 16:9 aspect ratio.
