Introduction

Sung-Chul Hohng is a notable inventor based in Seoul, South Korea. He has made significant contributions to the field of microscopy and photolithography, holding a total of 2 patents. His work focuses on advanced optical devices that enhance imaging and detection capabilities.

Latest Patents

One of his latest patents is a confocal fluorescence microscope. This innovative microscope consists of a light source unit that includes one or more short wavelength laser beams. It features a lens unit that converts parallel light emitted from the light source into linear light of appropriate size. Additionally, a multi-color mirror reflects the light source while allowing fluorescence to transmit, effectively separating the light source from the fluorescence. The device also includes a scan mirror that radiates the light source over a wide area and scatters the fluorescence onto a large-area camera. The microscope unit collects the emitted fluorescence from the target object and outputs the collected signal. A detecting unit is incorporated to remove background noise from the fluorescent signal, allowing for clearer observations.

Another significant patent is related to surface plasmon optic devices and radiating surface plasmon sources for photolithography. This device features a periodic array of apertures in a dielectric substrate with a metal film on top. It emits light from the metal-air interface and includes various components such as a surface plasmon generating apparatus and a surface plasmon detecting apparatus. The design allows for efficient reflection, division, and control of surface plasmon propagation, enhancing the capabilities of photolithography.
