A concave mirror is a spherical mirror with reflective surface curved inwards. Concave mirrors produce real and virtual images. These mirrors find applications in laser beam concentration and quality imaging. Holmarc's concave mirrors have protected aluminium coating and offer high reflection throughout UV, visible and NIR region. Custom sizes and focal lengths are available as well.
