In this post, we break down why these ultra low expansion materials are essential to aerospace and optics, what makes them so stable, and how they’re fabricated to meet the most demanding technical standards. Whether you're designing advanced mirrors, lenses, or filters, understanding ULE materials is key to building systems that stay precisely aligned—no matter the temperature.

A practical overview of common questions in optics manufacturing, emphasizing the gap between what customers often specify and what they actually need.  Highlighting how scratch/dig, flatness and homogeneity specifications can significantly increase cost and complexity without necessarily improving performance. 

By choosing Esco, you gain access to a trusted partner with expertise in precision optics, advanced manufacturing capabilities, and a commitment to delivering high-quality optical solutions tailored to your needs. 

SPIE’s Defense + Commercial Sensing (DCS) is an invaluable opportunity for Esco to engage with our customers and vendors, and demonstrate our commitment to advancing military and sensing technologies with precision infrared optics. If you’ll be attending, we’d love the opportunity to connect in person.
