摘要: The present invention provides an optical imaging lens. The optical imaging lens comprises five lens elements positioned in an order from an object side to an image side, each of which has an object-side surface facing the object side and an image-side surface facing the image side. Counting from the object side to the image side, the five lens are labeled as a first lens element, a second lens element, a third lens element, a fourth lens element and a fifth lens element, all of which have refracting power. Through controlling a variable air gap formed between two adjacent lens elements and parameters to meet an inequality, adjustment distance required for focusing the optical imaging lens will be shortened.
