Laser Optics

Befort develops and manufactures laser optics for a wide range of applications since more than 20 years. Befort offerings range from a simple AR coated protective glass with a high laser damage threshold to a complex focus readjustment unit for ultrashort pulse lasers (Zoombox). Our laser optics are made of high quality Schottglass or quartz glass. Befort coats the optics precisely for their wave length. The coating exhibits a particular high laser damage threshold (LDT). We develop and manufacture for you Laser mirrors (metallic or dielectric) Laser filters Laser optics Telecentric laser optics Ultrashort pulse laser optics

Knight Optical’s Low GDD Ultrafast Laser Mirrors are ideal for demanding laser applications, especially where femtosecond ultrafast lasers are utilised. Our product catalogue consists of 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. Their key features include: •Ion beam sputtered (IBS) coating which is compact and durable. •Reflection > 99.9% within their wavelength range of either 500-530nm or 1010-1050nm. •Available as 0° and 45° angle of incidence •Exhibit minimal group delay dispersion (GDD) to prevent pulse broadening •High laser induced damage threshold (LIDT) •Precision flatness and surface quality to minimise laser scattering All of the above are important criteria for mirrors used to form a laser resonator, making these laser mirrors ideal.

Differentiation between ANSI and DIN / EN ANSI eyeglass blinds differ from DIN / EN eyeglass blinds in terms of pressure levels, sealing strips and materials. In German-speaking countries, glasses blind disks are also called blind disks or throttle disks. However, the English terms “spectacle blind”, “blind paddle” are also often used in Germany. Pressure ratings according to ANSI in lbs The following pressure levels for blind disks according to ANSI are available 150, 300, 600, 900 and 1500 lbs. Sealing strips The following forms of sealing strips are available: SMF, FF, RF and RTJ. Materials The steel materials A 516 GR 60 and A 516 GR 70 are available. In the stainless steel sector, the materials TP 304 / L, TP 316 / L and TP 312 are possible.
