Optical convex mirrors are precision-engineered reflective components designed to diverge incident light, making them ideal for beam expansion, illumination control, and wide-field optical systems. Shapeoptics offers high-quality convex mirrors suitable for UV, VIS, and IR spectral regions, manufactured to meet demanding optical and environmental requirements.
Our convex mirrors are available in a wide range of configurations, including laser mirrors, metal-substrate mirrors, focusing mirrors, and specialty optical mirrors, with multiple reflective coating options to ensure optimal performance across specific wavelength bands. By selecting the appropriate coating and substrate, high reflectivity, durability, and long-term stability can be achieved even in challenging environments.
Convex vs. Concave Mirrors
Convex Mirrors
Reflect light from the outer (bulging) surface
Always form a virtual, upright image
Image appears on the same side as the object
Commonly used for beam expansion, wide-angle viewing, and illumination systems
Concave Mirrors
Reflect light from the inner (curved-in) surface
Can form real or virtual images, depending on object position
Often used for focusing and imaging applications
Reflective Coating Options (Typical Performance)
Choosing the proper coating ensures high reflectivity at the required wavelength or wavelength range:
Protected Aluminum: Ravg > 90% (0.4–0.7 μm)
Enhanced Aluminum: Ravg > 92% (0.45–0.65 μm)
Protected Silver:
Ravg > 95% (0.5–0.8 μm)
Ravg > 95% (2–10 μm)
Protected Gold:
Ravg > 95% (0.8–2 μm)
Ravg > 84% (0.7–0.8 μm)
Dielectric Mirror Coatings: Ravg > 99.99% (>400 nm)
