Problems solved by technology
[0015] The disadvantage of these protection methods is that they provide only temporary protection and must be removed before obtaining the glass or final optical system
A step to remove the protective layer must therefore be provided, which makes the manufacture of the optical system or the glass more tedious and complicated

Embodiment Construction
[0059] Several specific embodiments of the invention are described below. It is to be understood that the present invention is by no means limited to these particular embodiments and that other embodiments may, of course, be practiced.
[0060] like figure 1 As shown, the present invention relates to an optical system 10 comprising at least:
[0061] - an optical element 20 comprising a glass functional substrate 1 and an electrochromic stack 2 formed on the substrate 1, and
[0062] - a protective layer 3, which is provided on the electrochromic stack 2, said protective layer 3 comprising an inorganic lubricating compound.
[0063] A protective layer 3 can in particular be deposited on the electrochromic stack 2 .
[0064] Here, the electrochromic stack 2 comprises:
[0065] - the first transparent conductive layer,
[0066] - a working electrode disposed above the first transparent conductive layer,
[0067] - a counter electrode, which is arranged above the working el...

Abstract
The invention relates to an optical system (10) comprising:-an optical element (20) comprising a functional glass substrate (1) and an electrochromic stack (2) formed on the substrate (1), the electrochromic stack (2) comprises a first transparent conductive layer, a working electrode disposed over the first transparent conductive layer, a counter electrode disposed over the working electrode, a second transparent conductive layer disposed over the counter electrode, lithium ions introduced within the electrochromic stack, and a separate ion conductor layer preferably interposed between the electrode and the counter electrode; -a protective layer (3) disposed on the electrochromic stack (2), the protective layer (3) comprising an inorganic lubricating compound.
Description
technical field [0001] The present invention relates to an optical system, an insulating glass (vitrage isolant) including such an optical system, a method of manufacturing the insulating glass, and a related optical system protection method. Background technique [0002] These devices have certain characteristics that can be changed under the action of an appropriate power supply to change the state of the electrochromic device between a clear state and a colored state. Said characteristics that can be varied include, inter alia: transmission, absorption, reflection of electromagnetic radiation at certain wavelengths, especially in the visible and / or infrared range, or scattering of light. Changes in transmission usually occur in the optical (infrared, visible, ultraviolet) range and / or other ranges of electromagnetic radiation, and are thus referred to as devices with variable optical and / or energy properties, however the optical range is not necessarily the only relevant...
