Problems solved by technology

In the traditional process, due to the thin air layer between the first prism and the second prism, the operation accuracy is often not enough when laminating, and glue overflow is prone to occur, which leads to the scrapping of the internal total reflection prism

Embodiment Construction

[0029] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0030] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

Abstract

The invention discloses a total internal reflection prism comprising a first prism, a second prism, optical cement layers and optical oil layers. The first prism comprises a first bonding layer. The second prism comprises a second bonding layer. The first bonding layer is bonded with the second bonding layer through the optical cement layers to make the first prism and the second prism formed into an integral body. The optical oil layers are arranged in parallel on edges of the optical cement layers and bonded with the first bonding layer and the second bonding layer. In the total internal reflection prism, a layer of optical oil layer can be printed on the first bonding layer and / or the second bonding layer at first, then optical cement is applied onto the first bonding layer and / or the second bonding layer, and finally, the first bonding layer is bonded with the second bonding layer. The optical oil layers have a certain thickness and arranged between the first bonding layer and the second bonding layer, so the space between the first bonding layer and the second bonding layer can be controlled accurately to prevent the occurrence of the excessive cement condition in the bonding process. Meanwhile, a total internal reflection prism manufacturing method is further provided.

Description

technical field [0001] The invention relates to total reflection prism technology, in particular to an internal total reflection prism and a manufacturing method thereof. Background technique [0002] Today, total internal reflection (TIR, Total Internal Reflection) prisms are widely used in fields such as projectors and cameras. Since the internal total reflection prism is two triangular prism-shaped prisms, that is, the first prism and the second prism are laminated, and the first prism and the second prism must form a thinner air layer, so the lamination process has higher precision requirements. high. In the traditional process, due to the thin air layer between the first prism and the second prism, the operation accuracy is often not enough when laminating, and glue overflow is prone to occur, which leads to the scrapping of the internal total reflection prism. Contents of the invention [0003] Based on this, it is necessary to provide a method for manufacturing an...
