Problems solved by technology

[0005] However, in the molding method using a metal mold or the photolithography method, since the formation of the microlens requires a metal mold or a complicated manufacturing process, the cost of this part is increased. In addition, it is difficult to form a microlens of any shape at any position. lens problem
[0006] In addition, if only the droplet discharge method is used alone, although it is easy to form microlenses at any position, it is difficult to control their shape according to the desired shape.

Abstract

A micro lens is provided with proper optical characteristics, such as a condensing function. Furthermore, a fabrication method of a micro lens is provided as well as, an optical device, an optical transmitter, a laser printer head, and a laser printer. The micro lens is equipped with a lens member formed by a liquid droplet ejection method, including: a base member formed on a substrate, a lens member formed on an upper surface of the above-mentioned base member to which the lens material is ejected in a plurality of dots by the liquid droplet ejection method, the upper surface of the base member having a concavity and a convexity with at least a part of the upper surface of the base member being subjected to repellant treatment.

Description

technical field [0001] The invention relates to a microlens and a manufacturing method of the microlens, an optical device, an optical transmission device, a spray head for a laser printer and a laser printer. Background technique [0002] In recent years, optical devices having a plurality of tiny lenses called microlenses have been provided. Such an optical device includes, for example, a light-emitting device including a laser, an optical interconnection with an optical fiber, and a solid-state imaging device including a condensing lens for condensing incident light. [0003] However, the microlens constituting such an optical device has conventionally been formed by a molding method using a metal mold or a photolithography method (for example, refer to JP-A-2000-35504). [0004] In addition, in recent years, it has been proposed to form microlenses, which are fine patterns, using a liquid droplet discharge method used in printers and the like (for example, refer to JP-A...
