Front surface mirrors (1λ over 25mm)
What are you looking for in Stock?
This range of front surface mirror (first surface mirrors) are selected for guaranteed flatness of 1 wave over 25mm aperture and individually tested to ensure they meet specification.
These mid-range quality front surface mirrors are manufactured from standard pre-coated sheet material. We stock this range from UV though to infra-red to meet most scientific instrumentation applications.
Knight Optical stock range of front surface plane mirrors are manufactured from pre-coated stock sheets ranging from 145x100mm sheets to 1000mm square sheets in thicknesses of 1mm, 3mm and 6mm thk as standard.
We stock these 1 wave mirrors in a wide range of coatings to meet most applications:
- Enhanced aluminium 94%R for visible applications.
- 99.9% dielectric for laser use in visible applications.
- UV aluminium for UV applications down to 180nm.
- 98.5% dielectric for laser use in the NIR applications.
- Ion plated silver for NIR-2000nm applications.
- Protected gold for 750nm to far infra-red applications.
Our guaranteed 1 wave front surface mirrors are typically used in more demanding imaging applications where image quality is important.
