AR Coating

MULTI IR Visible Light—AR Anti-Reflection Coating/Anti-Reflective Coating is a core optical coating product developed specifically to optimize the light transmission performance of optical components in the visible light band. Its core function is to reduce the reflection loss of visible light on the optical surface through multi-layer dielectric film system design and advanced vacuum coating processes (such as ion beam sputtering and electron beam evaporation), while reducing stray light interference and significantly improving light transmission efficiency. As an important category of industrial optical coatings, it uses high-purity dielectric materials such as silicon oxide and titanium oxide, and is accurately adapted to the full 400-760nm visible light band or specific sub-bands (such as 550nm green light band, 650nm red light band). The reflectivity can be as low as less than 1%, and some high-end customized models can even reach less than 0.2%. It also has excellent environmental stability—within the temperature range of -40℃~85℃, the film has strong adhesion, wear resistance, moisture and heat resistance, and no film peeling or optical performance attenuation.

This product is widely used in optical lenses (such as DSLR camera lenses, security monitoring lenses), display devices (such as LCD screens, projector lenses), biomedical instruments (such as microscope optical components), industrial testing equipment (such as machine vision sensors) and other fields: in camera lenses, it can reduce glare and ghosting during backlight shooting and improve imaging clarity; on display screens, it can reduce ambient light reflection and enhance picture contrast and viewing angle; in biomedical testing, it can reduce the reflection loss of optical components and ensure the accuracy of detection signals.

In line with the "Custom Optical Filter" requirement in the keyword list, this antireflection coating from MULTI IR supports full-dimensional customization services: it can design exclusive film system solutions according to the customer's optical component substrate (such as optical glass, sapphire, resin), target band, and application scenario (such as harsh outdoor environment, precision laboratory), adjusting film thickness, transmittance indicators and protective performance; at the same time, it is compatible with standardized mass production and small-batch personalized customization, meeting the strict requirements of consumer electronics, industrial manufacturing, scientific research and medical fields, and is a key supporting component for improving the overall performance of visible light optical systems.
