Focusing (Concave) Mirrors | 聚焦反射鏡

Concave mirrors, also known as focusing mirrors, are ideal for applications that require efficient light collection and reflection to a focal point. Unlike lenses, concave mirrors do not introduce chromatic aberration, making them highly effective in precision imaging systems, beam shaping, and illumination setups.

Edmund Optics offers a wide selection of concave mirrors with either spherical or parabolic surface profiles and a variety of durable metallic coatings. Choose from Aluminum for enhanced reflectance in the UV and visible spectrum or Gold for high performance in the near-infrared (NIR) and infrared (IR) regions. Protected coatings improve environmental durability and long-term performance. Parabolic concave mirrors are especially useful when minimizing spherical aberration, and off-axis designs allow light to be focused away from the incident beam path—ideal for applications requiring beam steering or separation.

FAQ(s)

What is a concave mirror used for?

Concave mirrors focus light to a single point, making them ideal for beam shaping, imaging systems, and optical instrumentation.

How do I choose the right coating for my concave mirror?

Select coatings based on your wavelength range of interest, desired performance, and environmental conditions. Be sure to consider the mirror's intended usage (e.g., laser, imaging).

What focal lengths are available?

Focal lengths vary by diameter/dimension and radius of curvature. Edmund Optics offers a selection of focal lengths, ranging from approximately 4mm to 3200mm, for precision focusing needs.

Are these mirrors suitable for laser applications?

Yes, many within our selection support laser use. Check the laser damage threshold and coating type to match your laser specs.
