SPHERICAL VS. ASPHERIC LENSES

HOW THEY’RE USED IN IMAGING APPLICATIONS

Optical Lenses are often categorized by their shape. Two common surface shapes are spherical and aspherical. Each offers unique characteristics that make it suitable for different use cases.


JML Optical has been delivering custom-engineered optical solutions for nearly 50 years and is one of the leading optical manufacturers in America. We provide rapid design, prototyping, and fabrication services for demanding industries, including the semiconductor industry. Throughout this industry, wafer inspection equipment is used that requires complex assemblies featuring precision optics.

As semiconductor features have become smaller, the silicon wafers used as substrates have become larger.  This creates a demand for advanced inspection tools that can accurately assess the wafers quickly and reliably. JML Optical manufactures custom optics and optical assemblies that are vital to the semiconductor industry.

Applications 

Click to Expand

The technology used to manufacture semiconductor chips requires state-of-the-art inspection tools to ensure chip architecture and performance are accurate. These tools utilize high-quality optics, precision passive and active mechanics, and optical assemblies. 

Optics used in semiconductor manufacturing must be be high-performing and expertly manufactured. There are many uses for optical components and assemblies in the semiconductor industry, including:
