Cutting photovoltaic cells

High efficiency and low cost in a short time in prototype works, More economical than machining, More flexible working opportunity in design, Production at lower costs in a short time without requiring molds in small quantities, Using the material in the most efficient and waste-free way in production, Allowing production without molds, Cutting No crushing of the material since there is no contact with the material during cutting, Burr-free and minimum roughness cutting process

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:

TF Metals offers a flat sheet laser cutting service for sheet metal up to 30mm in iron/steel - stainless/aluminum. We have 2 laser cutting machines: - Fiber Laser Cutting HK N-Light Corona 12KW with automatic loading and unloading - CO2 Laser Cutting HK Panasonic 4KW

STEEC has been a pioneering company in cutting and laser micro-cutting in France. Since the first YAG industrial laser in France was installed in the premises of the company in 1983. 30 years ago STEEC developed unique know-how and competence in this field which it offers its customers as part of its subcontracting service. The company now has 5 laser cutting machines which enable it to meet a wide range of requirements. These machines, in which the company continually investing, have been custom designed according to STEEC specification in order to comply with the quality and precision standards demanded by the customers. Using its highly efficient innovating machines STEEC carries out very high precision cutting on flat and tubular parts with thickness ranging from 3mm to 2µm !
