Product Description

Focusing Mirrors, or Concave Mirrors, are often used in applications that require light collection. Focusing Mirrors are also ideal for use in imaging systems, as they do not introduce chromatic aberration. As light strikes the surface of a Concave Mirror, the mirror’s surface profile causes the reflected light to focus to a point.

Spherical metalic mirrors

Ebetter Optics offers a variety of Focusing Mirrors with a range of metallic mirror coatings, or with either spherical or parabolic surface profiles. Metallic mirror coatings include Aluminum or Gold. Aluminum metallic mirror coatings are ideal for enhancing the reflectance of Ultraviolet (UV) or Visible wavelengths. Gold metallic mirrors coatings are used for applications requiring high reflectance in the Near-Infrared (NIR) or Infrared (IR) regions. Protected mirror coatings increase the coating’s durability. Parabolic Focusing Mirrors do not introduce spherical aberration into the system. Off-axis parabolic surfaces redirect the reflected light so that the light is not focusing back towards the source.
