Embodiment

[0017] Example: a structure such as figure 1 As shown, an antistatic optical substrate preparation method, the process is as follows: clean the substrate - put the substrate on the jig (frame for fixing the substrate) - put the jig into the vacuum machine - -Evacuate the vacuum machine to a certain condition--coating process (the specific process is as follows)--the machine is deflated--take out the substrate.

[0018] Coating process: After the substrate is cleaned, it is placed in a vacuum and pumped to 1x10 -5 Torr to 5x10 -5 In Torr’s high-vacuum machine, alternating high-refractive index film layers and low-refractive index coating layers are sequentially deposited on the substrate, and then the super waterproof coating material WR5 is evaporated and deposited on the film layer in a molecular state to form a new A film layer, and the thickness of the WR5 new film layer is 120-220nm, take out the substrate to form an antistatic optical substrate.

[0019] The at least o...

Abstract

The invention discloses an antistatic optical substrate preparation method, pertaining to the lens coated optics manufacturing technology. The method includes: cleaning the substrate and then placing in a fine vacuum machine whose vacuum degree is pumped to1*10 [-5] Torr to 5*10 [-5] Torr, depositing a film with alternated high refractivity film layer and low refractivity coating film layer in sequence on the substrate, and then evaporating a super water proof coating material WR5 and then evaporating and placing on the film layer in molecular status to form a new layer of film (wherein, the film thickness is 120-220nm), and then removing the substrate to form an antistatic optical substrate. The optical lens can play an antistatic (electrostatic isolation) role, which is not liable to adsorb dust and can remain cleanly and sanitary for a long time.

Description

technical field [0001] The invention discloses a method for preparing an antistatic optical substrate, which belongs to the technical field of lens coating optical manufacturing technology. Background technique [0002] Static electricity is an objective natural phenomenon, which can be produced in many ways, such as contact and friction. Static electricity is characterized by high voltage, low power, small current and short action time. Electrostatic discharge is the abbreviation of Electro-Static discharge. When two materials are separated, either by pressure or by frictional contact, electrons are freed from the surfaces of the materials, creating an electrostatic zone. The surface of a material with fewer electrons is positively charged, while the surface of a material with excess electrons is negatively charged. These two charged materials will attract surrounding materials with opposite charges to neutralize the charge. If the charged material is conductive, then sta...
