![]() ![]() ![]() Leica Geosystems therefore uses either the stated reflective coating or a patented system for the prevention of fogging and condensation. Errors occur in the use of prisms without copper coating on the back side when moisture droplets accumulate or the prism becomes foggy. Measurement errors occur frequently at close ranges when prisms without anti-reflex coating are used, as the front of a prism always directly reflects a certain percentage of a signal. The faces other than the top and bottom of a. For example, if a prism has a triangular base it is called a triangular prism. A prism is named after the shape of these bases. The top and bottom faces are identical and are called bases. The production process of these coatings is so complex that only a very few manufacturers worldwide meet the requirements of Leica original prisms. A prism is a solid shape that is bound on all its sides by plane faces. An additional anti-reflex coating on the sensitive front surface of the prism provides a tough resistance to scratches. Working together, the copper coating and the lacquer increase the life of the prism significantly. The special adhesive lacquer protects the underlying layers from corrosion and detachment. In contrast to many conventional prisms, the reflective copper coating on the reverse side of Original prisms consists of a support coating, a vacuum-metallised copper coating, a protective coating and an overlying coat of lacquer. The returned signal quality defines the maximum range of a measurement. The smaller the beam deviation (measured in angle seconds), the greater the directly reflected signal strength to the sender optic. The beam deviation of a prism defines the its maximum range, according to the principle "entering beam should equal the exiting beam". The smallest dimensional change in the geometry of a glass prism or on the holder can lead to a deviation from the centring axis and thereby create measurement errors. The holder and the prism constitute a unit with which the centring and repeat accuracy is defined. Substitutes are not configured according to Leica Geosystems criterion and often exhibit displacement between prism, holder and recording pin. Measurement errors occur if Original prism holders are not used. Professional 1000: COST EFFECTIVE MEASURING These are standard prisms, special prisms, mini prisms as well as monitoring prisms. ![]() Leica Geosystems offers a transparent selection of prisms in various sizes for different areas of application. The glass dimensions, the position in the holder and with it the areal orientation, are important for measuring accuracy. The workmanship and the durability of the copper coating are decisive for a long life. Without these, the range of distance measuring, ATR and Powersearch would be reduced by up to 30%. A number of Original prisms from Leica Geosystems have a special coating on the reflective surfaces – the Anti-Reflex Coating, and a copper coating on the reverse side. _dialogService.ShowNotification(message, r =>Įlse if (r.Result = ButtonResult.The range of a prism results from, among other things, its coating and the glass geometry. Then to call your Notifications use the new and improved API that you created specifically for your app. _closeDialogCommand ? (_closeDialogCommand = new DelegateCommand(CloseDialog)) Public DelegateCommand CloseDialogCommand => Private DelegateCommand _closeDialogCommand public class NotificationDialogViewModel : BindableBase, IDialogAware Here is a simple example of what an IDialogAware ViewModel may look like. Void OnDialogOpened(IDialogParameters parameters) Next you need a ViewModel that implements IDialogAware which is defined as follows public interface IDialogAware Preferably, it will utilize the ViewModelLocator The only requirement it has a ViewModel that implements IDialogAware set as it's DataContext. Your dialog view is a simple UserControl that can be designed anyway you please. ![]()
