Borosilicate glass is a silica-based glass with boron trioxide added to the mix. That one addition changes how the glass behaves under heat and chemical attack enough that it's become the default choice anywhere ordinary glass isn't tough enough — lab glassware, high-end cookware, and precision optical and industrial components.

Optical prisms redirect, invert, rotate, or split light using refraction and reflection rather than a curved surface. Because the same basic block of glass can do very different jobs depending on its geometry, picking the right prism starts with knowing exactly what you need the beam or image to do.

An achromatic doublet — often just called an achromat or achromatic lens — is made of two glass elements with different refractive index and dispersion, cemented together. That combination brings two design wavelengths to a common focal point, which sharply reduces chromatic aberration compared with a single lens element. It's the go-to...
