Stable solution of the seven most common brain metabolites at physiological pH and concentrations. Two sizes available: 18cm and 11cm diameter spheres. Assess the performance and reproducibility of both standard and edited Magnetic Resonance Spectroscopy sequencees. he SPECTRE (Spectroscopy Reference) phantom is designed for Quality Assurance measurements of Magnetic Resonance Spectroscopy (MRS). It contains a set of metabolites found within the brain at physiological concentrations and pH, all housed within a HDPE spherical shell. Up to 30 SPECTRE phantoms can be made from the same batch, providing identical phantoms for use in multi-centre studies. SPECTRE uses a set of metabolites typically used in MRS QA; with the addition of GABA (gamma-Aminobytyric acid) at 2mM, to allow performance testing of both standard (e.g. PRESS, LASER) and J-edited (e.g. MEGA-PRESS) MRS acquisitions.

Knight Optical offer a range of Stock N-BK7 Precision Grade Windows, for use with Thermal Imagining Cameras. Infrared radiation is characterised by the wavelengths ranging from 750nm to 1000µm. Although typically used for the visible range, N-BK7 does have transmission within the near infrared spectrum also. Where IR materials such as Germanium are limited to a small band in the IR spectrum, N-BK7 works well throughout the entire visible and into the NIR, making it a perfect material for a protective window for using within a Thermal Imaging Camera. A low cost material, it is perfect substrate for your protective window. We can supply both stock and custom N-BK7 windows to protect your thermal imaging application. The high optical quality and uniform transmission of N-BK7 as well as low absorption in the entire visible wavelength range is a key feature for this application.

Knight Optical are very experienced within the Thermal Imaging market, including anti-reflective and diamond-like-carbon coatings used on the optical components in these systems. Knight Optical know exactly what you are looking for. Thermal imaging uses infrared materials such as Germanium and Silicon, however in there raw form the transmission is not the best it could be. For example, Germanium typically transmits at <45% but with an AR coating applied, it can improve transmission to >60%. This increase in transmission means that the camera sensor receives a better signal through the protective window. Also with protective windows, we can provide high quality DLC coatings. We ensure the coating is Salt Fog Tested to MIL-SPEC standard to ensure that the coating withstands harsh environments. The coating has high mechanical hardness and high resilience to external stress. Read PDF for more information

Knight Optical offer a range of Stock Sapphire Windows, for use within Infrared Systems. Knight Optical can offer Sapphire (Al2O3) Optics for Infra-red systems over the waveband of 0.2 to 5µm.

Knight Optical can offer Custom Homogenizing Rods for use within Fluorescence Imaging. Knight Optical supply precision optical components to customers in the medical industry for applications such as fluorescence illumination, microscopy and imaging. Homogenizing Rods are used within the application of surgical procedures; within systems designed to help identify which tissues have been exposed to the fluorescent indicator. The Light source will enter a light pipe at a variety of incident angles, which is designed to utilise its total internal reflection to channel the light from the entrance of the light pipe to the exit. The material’s refractive index is the only factor which affects the light pipes critical angle; this defines the angle of acceptance which the total internal reflection will occur at. With this it helps to control the light source being used in medical systems.

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 **
