Knight Optical’s Lithium Fluoride Windows for UV Applications

08 Jun 2020

Knight Optical can offer Lithium Fluoride Windows for use within UV Applications.

We supply a range of lithium fluoride windows for a range of applications.  All individually QA checked and metrology tested for quality to ensure parts meet customer specification.  Supplied in a range of sizes and shapes with custom coatings tailored to meet your individual applications.

Knight Optical supply precision optical components to customers using UV optics such as UV lasers. UV lasers are beneficial in some applications as opposed to longer wavelengths such as infrared or visible light as they do not heat the areas around the target. This allows the laser the cut materials by breaking atomic bonds, rather than melting the material.

Due to the large band gap for Lithium fluoride, it’s crystals are more transmittive to short wavelength UV radiation than any other material and are ideal for use in X-Ray monochromators, as for use in VUV, UV, Vis and IR spectrums.

Typical specs:

Material:                                             Lithium Fluoride (LiF)

Shape:                                                  LiF Circular Windows, LiF Square Windows

Dimensional Tolerances:              +/- 0.1mm

Parallelism:                                        < 3 arcminutes

Surface Quality:                                                               < 0.5 λ PV@ 633nm

Coating:                                               Antireflective coatings for application bandwidth (if required)

                                                                Typically BBAR @1-6μm

Diamond-Like Carbon (DLC) coating @1-6μm

All our Lithium Fluoride Windows are fully inspected on their quality in our ISO 9001 certified, state-of-the-art Metrology laboratory, using our Zygo Verifire Interferometer and Trioptics PrismMaster. This allows us to work to the highest QA standards and meet the tolerance specifications on these precision components.
