With rapid advances in electronics and wireless technology, electromagnetic interference (EMI) has become a major concern, often impacting the performance of sensitive equipment. ESGs have therefore become crucial, especially in optical machining, where electromagnetic stability is key. These fine metal meshes act as barriers against electromagnetic waves, creating a controlled environment that allows for high-accuracy operations. Here’s a closer look at how ESGs work, their core parameters, different types, and the roles they play in optical machining.
What is an Electromagnetic Shielding Grid?
An electromagnetic shielding grid is a metal mesh structure designed to reduce or block electromagnetic waves, EMI from affecting nearby devices. ESGs work by reflecting or absorbing the electromagnetic waves, creating a buffer zone around sensitive electronic or optical equipment. In optical machining—where accuracy is paramount—their use minimizes interference that could skew measurements, affect equipment stability, or impact machining quality.
