An optical mirror reflects light using a coated surface rather than refraction, which makes it useful anywhere a lens's chromatic aberration or transmission loss would get in the way. Choosing the right one comes down to two decisions: what surface shape you need, and what coating will reflect your wavelength efficiently.

Borosilicate glass and fused silica both handle heat better than ordinary glass, but they're not interchangeable. Fused silica pushes every one of borosilicate's advantages further — at a meaningfully higher price. Key Comparison Property Borosilicate Glass Fused Silica Composition SiO2 + B2O3 (+ minor oxides) 99.9%+ pure SiO2 Thermal expansion coefficient ~3.3 × 10⁻⁶ /°C ~0.5 × 10⁻⁶ /°C Max use temperature...

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...

Ultra-thin glass is glass thin enough to flex — in some cases enough to fold — while keeping the scratch resistance, chemical stability, and optical clarity of standard glass. The property that makes it useful isn't the material itself; it's simply how thin it can be made without breaking. Key Specifications at a Glance Parameter Typical Value Thickness range 0.03 mm–1.1 mm...

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...

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. Key Specifications at a Glance Property Typical Value Main components SiO2, B2O3,...
