vorgestellt Optical Mirror Buying Guide: Flat, Concave & Convex Mirrors
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. Key Specifications at a Glance Parameter Common Options Common substrates N-BK7,...

Plano-Convex vs. Biconvex Lens: Differences & Focal Length Formulas
Plano-convex and biconvex lenses are the two most common positive (converging) lens shapes. Both bend parallel light rays to a focus; the difference is that a plano-convex lens has only one curved surface, while a biconvex lens has two. Key Specifications at a Glance Parameter Typical Value Substrate N-BK7, UV fused silica Diameter 5 mm–100 mm Focal length range 15 mm–1000 mm...
