Concave mirrors (quality grade)

What are you looking for in Stock?

Concave mirrors can be used to create images of light sources.  Concave mirrors can be tricky to use as the object and image will now exist in the same space. However concave mirrors have one incredible characteristic in that the image location and quality is completely independent of the wavelength and so does not create chromatic aberration unlike equivalent lens optics. This allows the design of very wide spectral range instruments and does allow a system that will work in the IR to be aligned using visible light.

Concave mirrors are typically used in reflecting telescope, electron microscopes and a range of scientific instrumentation applications where there is a requirement to image distant objects.  

Our range of quality concave mirrors are coated for use in the visible and near infra-red regions.  We can also strip the aluminium coating from our stock concave mirrors and coat with a desired coating, i.e. Protected Gold or UV aluminium.  This can be done at short notice to create your bespoke custom concave mirror.  This can be very helpful with development work.
