Knight Optical offer a complete range of Stock Polarisers for a range of applications that could be used for Head-mounted Displays. Our stock polarisers cover wavebands <0.2 to >2µm, we can also supply custom polariser options made to your complete custom specifications. A head-mounted display (abbreviated to HMD), is a display device worn on the head or part of a helmet that has a small display optic in front of one (monocular HMD) or both eyes (binocular HMD) and can be used in applications within gaming, aviation, engineering and medicine. There are also optical head-mounted display (OHMD) which is a wearable display that can reflect projected images and allows a user to see through it (often used in conjunction with a Beamsplitters).

Enercon has two coil design types, each with several variations, to ensure the perfect coil is available for the size and type of your container and cap for your application to deliver perfect, consistent seals. Tunnel coils facilitate higher throughputs than the more traditional flat coils. The Deep Tunnel Coil is used for conical, spouted and other shaped caps. The All-in-One Coil is a variation of the Flat Coil. It is available with the Super Seal™ range and Super Seal™ Touch. This flat sealing head can be pivoted to accommodate various applications. Capable of sealing containers with cap diameters ranging from 20mm to 140mm, it is ideal for packagers who seal a variety of containers and offer the highest degree of sealing versatility. Packagers often don’t realise that the efficiency of the sealing operation depends on the design of the sealing head.

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 use of a head gradient coil insert together with a whole body gradient coil allows for higher gradient strength and potentially higher stimulation limits. The use of a head gradient coil insert can result in higher resolution imaging, in particular of the inner ear. (Head gradients are used in combination with Whole body gradients within MRI systems for superior imaging). Important factors in head gradient coil design are: - Design of the head gradient coil insert's magnetic field to match the whole body gradient's magnetic field, - Robust, durable and rigid construction to maintain a fixed position within the whole body magnetic field, - Efficient cooling of the head gradient. ** Click for more **
