WebA projection lens is the part of a projector that magnifies an image and casts it onto a screen. These lenses typically feature multiple lens elements and come in two main types: zoom and fixed focus. Zoom projection … WebNov 3, 2024 · Figure: Out-lens Method and In-lens Method. The higher resolution is the in-lens method, which shortens the focal length, but it cannot be used if the sample is affected by a magnetic field. In that case, the out-lens method, which is less affected by the magnetic field, will be used.

Understanding Camera Zoom & Lens Focal Length

WebUsing the average value of your focal length measurements, calculate the image distance i if the object distance is 1.5 x your focal length (e.g, if your measured focal length were 10 cm, you would do the calculation for an object distance of 15 cm).
