Abstract

The invention discloses a lightweight surface glass Ti metal plane reflector, comprising Ti metal substrate, special type glass layer and reflecting film, where the Ti metal substrate is of pure Ti (TA1,TA2 or TA3), or Ti alloy (TC1, TC2, TC3, TC4, or TC6), and is of a plate structure or of a cellular structure with lightweight design, and the Ti substrate surface is processed by machining or laser method and has roughness of 0.8-15 mu m, and the special type glass layer is 0.2-2.5mm thick and comprises SiO2 25-40wt%, PbO 50-70wt%,R2 O1-5wt%,RO 0-2wt%, and As2O3 0.2-0.5wt%, and has expansion coefficient of 80-90*10-7 / deg.C; the reflecting film is a metal reflecting film vacuum-plated on the special type glass layer and having high reflection ratio. And its advantages: properties of special type glass and Ti metal match, its structure is simple, convenient to install and debug, and applied to optical systems in various fields of spaceflight, aviation, weapon, etc.

Description

technical field

[0001] The invention relates to an optical device, in particular to a light-weight surface vitrified titanium metal plane reflector of a military optical system, and also relates to a special glass formula used in the reflector. Background technique

[0002] With the continuous development of precision guidance, fire control, radar, aerospace remote sensing and other technologies, higher requirements are put forward for military optical systems, requiring reflectors to have good imaging quality in a wide range of electromagnetic bands. In addition to meeting optical requirements In addition, it is also required to increase the aperture, reduce the quality of the mirror and improve the imaging stability.

[0003] At present, the reflectors mainly include: 1. Glass reflectors. This solution uses glass as a mirror, bonded to a metal substrate with epoxy resin. Glass is a traditional optical material with good optical performance and optical processability, and...
