As well as Knight Optical’s Low GDD Ultrafast Laser Mirrors, we can also provide broadband and wide-angle alternatives to cover more of a range of applications. Our Wide-Angle Laser Mirrors optimised for the fundamental and second harmonic (SHG) emissions of Ytterbium (Yb) doped lasers including diode-pumped solid-state (DPSS) and fiber lasers, and therefore have a design wavelength of either 515nm or 1030nm. They exhibit > 99.9% reflection when used between 0 to 45°. The Broadband Laser Mirrors work from 700-900nm ideal for applications using a Ti:Sapphire laser, again demonstrating > 99.9% reflection within this wavelength range. Their key features include: •Ion beam sputtered (IBS) coating which is compact and durable. •Reflection > 99.9% within their design wavelength range. •Broadband laser mirrors work at 45° •Exhibit minimal group delay dispersion (GDD) to prevent pulse broadening •High laser induced damage threshold (LIDT) •Precision flatness and surface quality to Material::UV Fused Silica Diameter::+0/-0.1mm Thickness::+/-0.1mm Surface Quality S1:< 10/5 for 12.7mm/25.4mm diameters Surface Quality S2::< 80/50 Flatness Clear Aperture::80% or specified aperture Parallelism::< 5 arc mins Chamfer::0.1-0.4mm Coating S1::R>99.9% @ 700-900nm, AOI 45°, |GDD Rs| < 20 fs2

Knight Optical can offer dichroic bandblocking filters for use in Fluorescence Microscopy. We supply a range of dichroic bandblocking filters 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 in fluorescence microscopy. Dichroic bandblocking filters are used to block a specific wavelength band and transmit the rest. Our Dichroic bandblocking filters are usually made for bands between 300-1200nm. Our dichroic filters are usually specced for a 0° AOI. Use at a 45° results in a CWL shift of around 35-50nm. They are used as beamsplitters in fluorescence microscopy to transmitting For more information read PDF….
