Optical films - Import export

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:

Key characteristics and advantages of this film: Three-layer structure : The film has a complex three-layer structure, which makes it durable and reliable. Heat-Sealable Layers : Two heat-sealable layers provide excellent sealing characteristics, making this film an ideal choice for packaging and sealed packaging solutions. Antistatic properties : The material does not slip and does not accumulate a static charge, which makes it convenient and safe to use. Optical Properties : The transparency and optical clarity of this film ensures that the packaged product remains visible and attractive to customers. Anti-glare properties : Additional anti-glare properties help prevent glare and reflections on packaging, making it more attractive and informative. Food Approval : This film is used to package a wide range of food products, which emphasizes their safety and compliance with quality standards.

+ big availability on the market + good sealing properties + has very good slow puncture resistance, however the tearing strength is very low - bad optical properties (the film is milky) - the mechanical properties of the film are average

+ it's possible to downgauge with 20% from LDPE without loss of mechanical properties + Has good shrinking properties - The film is sensible to electric statisticity - The optical properties of the film are average - Possbible formation of angel hair when cut-sealed

It is a very fine and pure talc specially developed for release polyolefin films. It provides very good mechanical properties of the film without compromising optical properties. This talc makes it possible to obtain highly filled compounds.
