L/10 Mirrors from Knight OpticaL

Knight Optical can offer you stock and custom lambda/10 mirrors for use in Spectromters, in a range of materials such as BK7 or equivalent, Zerodur, Quartz, UV Fused Silica and many more. Mirrors are made from low expansion glass for optimum stability to maintain the lambda/10 flatness. The mirrors help produce high quality signals and can be coated with a variety of coatings to ensure that the perfect quality image in the wavelength you require is achieved: •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 Lambda/10 mirrors are used to produce a better quality signal from the mirror, resulting in a higher quality result for transmission.

Knight Optical can offer Toroidal Mirrors for use within Optical Systems. We supply a range of Toroidal Mirrors 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 with Optical Systems. Our Toroidal Mirrors are designed to minimise astigmatism when used in off-axis geometry. They are easier to manufacture than parabolic or ellipsoidal mirrors and therefore can be made much cheap with the same quality. Toroidal mirrors are used for correction of aberration in a range of scientific instrument applications such as spectroscopes monochromators and imaging devices. For more details read PDF…

The laser mirrors can be custom made to include the following range: 1 YAG laser mirrors (High power grade) 2 Excimer laser mirrors (High power grade) 3 Argon-ion laser mirrors (High power grade) 4 Diode & broadband (Ti:Sapphire) These mirrors are made from vacuum depositing thin films of material that have differing refractive indices & thickness onto suitable substrates. Typical custom laser mirror substrates are calcium fluoride, germanium, sapphire, fused silica and Zinc Selenide which produce a high efficiency reflecting surface at the laser wavelength. The coatings are assembled assuming that the mirror will be working in the plane of incidence. This is essential as any off-axis angles will push the pass band toward the shorter waveband that could be beyond the pass band for one or both polarizations (s and p). If off-axis reflections are needed, such as at 90°, then this coating needs to be applied for an Angle of Incidence (AOI) of 45°. READ PDF FOR MORE INFO ..
