Knight Optical can offer UV Fused Silica Lenses for Flame Detection Applications. UV Fused Silica can be used in Flame Detection Applications, due to its high transmission into the NIR range (approximately <92% avg 400-2000nm) meaning that a clear distinction can be made between different wavelengths of light. UV FS also has a very low coefficient of thermal expansion 0.55x10-6K-1 at 300K) compared to N-BK7 (7.1x10-6K-1), meaning that it can still provide optical performance under high temperature. UV FS also has a high melting point compared to N-BK7, providing further protection for your application in high temperature environments. UV FS is comparable to N-BK7 or other similar optical glasses in its performance, having a very similar average transmission over the VIS range up to approximately 2000nm and a slightly lower refractive index. The Abbe constants of UV FS are also very similar to that of N-BK7, although slightly higher. Read PDF for more info

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 Heat Shielding. Infra-red interference Shortpass filters are designed to transmit wavelengths shorter than the “cut-off” of the filter and to block bands above that. In many systems that require heat shielding while still needing visibility a shortpass filter can be used. These can attenuate infrared radiation and allow through visible light, which allows your temperature sensitive equipment to be visible. They can also be paired with a longpass filter to make a bandpass filters. Read PDF for more Information…..

The Star HM range are bag sealers designed for lighter gauges of materials. The impulse sealers are capable of sealing up to 250 µm (1000g). There is also a constant heat machine for laminates and complex materials. Both hand and foot operated machines are finished in painted mild steel. A stainless steel food shop counter top bag sealer and tube sealer are also available. The robust construction allows for years of service with a full spares and service back up. Removable sealing bars allow for ease of maintenance and replacement of consumable items.

The Star 56 range of bag sealers consists of a power pack and a set of sealing jaws designed for heat sealing products in situ or for a bag sealer to be incorporated into a parent machine. The range of sealing heads is ideal for uses such as sealing valve sacks, foil or plastic machinery covers and sealing straps onto bulk bags. We also produce a range for sealing dangerous/ toxic products where the seal incorporates a cut so no product can escape. Seal cycle initiation can be via foot switch, push button or automatic (when the jaws are closed). The power pack is connected to the jaws by a lead, allowing the jaws to be used in awkward positions. Adjustable weld and cool timers control the sealing cycle, allowing them to be used on most materials. The indicator lights on the power pack or sealing jaws advise the operator when the weld and cool cycle are complete. Special sealing heads producing shaped welds can be made for almost any application.

The Star Platen Sealer is available either bench-mounted or free-standing, producing shaped or multiple welds. The Star Platen Sealer can be manually or pneumatically operated with either foot switch or push button operation. The Star Platen Sealer can seal most modern plastic, biodegradable, foil, paper and laminate packaging materials and is constructed from anodised aluminium profile to give rigidity whilst keeping the weight down. The Star Platen Sealer is available with: A variety of seal shapes, sizes and widths Multiple seals can be produced at the same time Automatic cutter for a straight or shaped cut out A variety of jaw openings dependant on application Interchangeable sealing heads for different welds from the same machine Either one or both jaws heated A range of control options are available including the ARTICS and MkVI C controllers

The Star Medical sealers have been developed for applications where ease of cleaning is critical, such as in the food, medical and pharmaceutical industries. The machine body can be built in a number of different designs with the jaws operating vertically (when a product is best sealed laying down) or horizontally (when a product is best sealed standing up). With the cylinders moving the top jaw directly, jaw alignment and pressure are much more controllable. This machine design is available with all the Star controllers. The Star Medical Vacuum sealer allows for the air to be removed from a bag prior to sealing. The machine is available with a range of vacuum pumps or vacuum generators dependant on your application. Gas flushing is available for modified atmosphere packaging. This machine design is available with either our ARTICS or Medical controllers.

The Star 66 free-standing sealer is designed specifically for sealing bags where the product is best standing upright. Typically, this lends itself to the bagging of bulk product such as aggregates, prepared foods and chemicals. The Star 66 is available in a range of formats to suit the product, working environment and bag type. The rugged, powder coated mild steel body is built to withstand the rigours of hostile working environments, such as builders' yards or coal merchants. The foot switch initiated solenoid jaw operation allows the operator to be preparing the next bag whilst one is being sealed. An IP65 stainless steel machine is available for food environments. Constant heat jaws for heavy weight foil and multi-wall bags are also available. For applications where seal quality is paramount, such as hygroscopic compounds, the Star MkVI C or ARTICS controller should be specified.

The Star 96 is available as a bench mounted or free-standing bag sealer, designed for sealing bags when the product can be laid down. The Star 96 is the industry standard, sealing a whole host of products ranging from pet bedding to pharmaceutical supplies. The Star 96 is solenoid operated as standard, with foot switch operation. The solenoids close the jaws and keep them closed for the duration of the weld and cool cycle, allowing the operator to prepare the next bag. If the machine is being used quickly, the Star MkVI timer board can be set to compensate the heat built up. A variety of product support tables and machines are available on request. Constant heat machines are available for special bag materials such as paper bags. For the sealing of medical and pharmaceutical products, the Star ARTICS controller can be specified to give unparalleled seal quality and consistency.

ISPM15 is an international standard for phytosanitary measures which is being progressively implemented throughout the world. Already some 28 countries have adopted the standard; a further 21 are in the progress of doing so and about another hundred countries have signalled their intension to bring the requirement to their national regulations. Countries which have signed up to ispm-15 are entitled to refuse entry at their frontiers to goods on wooden pallets, crates, spools or any other wood packaging unless it has been treated, marked and certified in accordance with their regulations. Associated Pallets Ltd has been providing a heat treatment which meets the demands of ISPM-15 and since the introduction of the plant some four years ago, has become experienced in all needs of the wood packaging producer and user.
