✨ Introducing the classic... the reliable... double Gauss lens design

✏️ This optical design was created in 1888 and is still a go-to way to reduce optical aberrations over a large focal plane

🔭 The doubled elements result in wider apertures than many other lens types, especially when made unsymmetrical

📝 Double Gauss lenses typically have little field curvature or chromatic aberration, but they do often suffer from oblique spherical aberration and astigmatism
