Knight Optical supplies a range of custom UV grade mirrors for use as reflectors specifically for ultraviolet applications between 180nm and 400nm.
UV grade custom concave mirrors: We offer UV grade custom concave mirrors, also known as focussing mirrors. Concave mirrors work in precisely the way one would expect, focussing light to a point. The choice of substrate is generally unimportant for optical mirrors as performance depends on coatings however a choice of suitable materials are available for your specific custom UV mirror requirement. High quality aluminium/Mgf² protective overcoat is applied achieving over 85% reflection at 180nm to 650nm, however alternative UV coatings are available for your custom UV mirror.
We are able to provide custom UV grade concave mirrors with increased performance and tight tolerances for imaging quality. Custom UV grade concave mirrors can be supplied with short focal lengths to long focal lengths over 2000mm long. Diameters are unrestricted however generally range from 5mm to over 350mm diameter.
UV grade custom plain mirrors: UV grade custom plane mirrors also known as front surface mirrors or first surface mirrors are used in beam steering or reflecting in a range of UV applications. Our custom UV range of plain mirrors specifically for use in UV applications are generally coated with aluminium/ Mgf² protective overlay coating suitable for use at 180nm. Custom UV mirrors can be supplied as UV grade precision λ/4 front surface mirrors which have tightly controlled precision polished flat faces. Custom UV grade general purpose front surface mirrors are made from high quality float glass and are generally available in thicknesses of 1mm, 3mm and 6mm thk as standard. Coating runs are maximised with 145x100mm plates so that we remain competitive, these savings are passed onto our customers.
We can also provide custom mirrors in a wide range of coatings to meet most applications:
- Enhanced aluminium coating, 94% reflectivity for use in visible applications.
- 99.9% dielectric coating for laser use in visible applications.
- 98.5% dielectric coating for laser use in the near infra-red region.
- Ion plated protected silver for use in NIR to 2000nm.
- Protected gold for use from 750nm to far infra-red applications.
Stock UV mirrors can also be edges to smaller diameters and other shapes at short notice to produce your custom UV mirror at short notice.
Knight Optical supply high quality custom UV grade mirrors made to our exact specification. Every component is individually tested on our Agilent Cary 5000 spectrophotometers fitted with UMA and DRA devices which operates from 175nm to 3200nm. Our UMA accessory can test reflection and transmission at any angle of incidence (AOI) Our Agilent 660 FTIR spectrophotometer is used for testing spectrums between 3.5µm and 45µm. All tested by our highly skilled technicians in our state of art metrology lab to ensure all components meet our high quality standards.
