Low-iron glass is soda-lime glass with the iron content stripped down. That single change is the whole story — but it has a visible effect on color and a measurable effect on light transmission, which is why the two aren't interchangeable in every application. Key Comparison Property Standard Soda-Lime Glass Low-Iron Glass Base composition Soda-lime-silica Soda-lime-silica, low-iron sand Iron oxide content Higher...

Soda-lime glass and borosilicate glass are both silica-based, but a difference in composition gives them very different performance under heat — and that difference decides which one belongs in your application. Key Comparison Property Soda-Lime Glass Borosilicate Glass Main components SiO2, Na2O, CaO SiO2, B2O3, Na2O, Al2O3 Thermal expansion coefficient ~9 × 10⁻⁶ /°C ~3.3 × 10⁻⁶ /°C Thermal shock resistance Moderate...

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.
