Knight Optical’s Laser Optics range include Thin Film Polarisers which separate the s- and p-polarised light with negligible absorbance within the coating for low loss performance. The laser thin film polarisers are optimised for 515nm and 1030nm design wavelengths, ideal for Ytterbium (Yb) doped lasers including diode-pumped solid-state lasers (DPSSL) and fiber lasers, as well as Nd:YAG lasers emitting at 1064nm. Currently, we stock thin film polarisers which work at either 45° or at Brewster angle (55.4°), both of which have been coated using ion beam sputtered (IBS) technology, creating a compact and durable coating, with a LIDT suited for ultrafast laser applications. Often used within a laser resonator to separate the different polarisation states and can be used as an alternative to polarising beamsplitter cubes or Glan-type polarising prisms. The following are the tolerances for the laser polarisers:

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

inear precision growing line systems for use in the production of wind towers, monopiles, pipes and more. Since 2002, we have designed, manufactured and supplied Fit Up and Growing Line Systems that optimise the production of onshore and offshore monopiles, towers, pipes, tanks and more. Key Plant growing line and automated can joining systems enable individual motorised adjustment of each axis under load, the work piece sections can be manipulated left, right, up, down (X, Y, Z axis) to join the cans together. We manufacture linear precision systems with ball screw operation for smooth precision control and hydraulic options for thin wall material. Key Plant growing line and ACJS systems reduce time & cost, increase customer productivity and gives a consistence to the fitting up and joining of cans.

Enhance your automated welding processes for inner, outer, circumferential and longitudinal welding applications with Key Plant column and boom welding manipulators. Key Plant column and boom manipulators are developed to upgrade your fabrication throughput, and augment the quality of your weld production. We supply machines for a range of manufacturing environments; from pipe fabrication shops to tanker assembly lines, Key Plant provide the best solution to suit your project requirements. Key Plant have built a portfolio of global leading column and boom welding manipulators, available to buy, rent or lease. Our range consists of Mobile Pipe, Standard, Extra-Heavy and Telescopic models. But if your project demands are non-typical, our in-house capabilities and next-level engineering expertise enable us to develop special purpose machines for those more ‘complexed’ project needs.

Our heavy duty, built to last conventional welding rotators are designed and manufactured to tolerate the hardest, hard-wearing and unrelenting workload environments. The powered drive units are controlled by a five-function pendant with a variable speed potentiometer, giving the operator full control of the rotating workpiece.
