In case of smallest image details and large magnifications please use macro-lenses which are specially designed for these applications.įurther details on optical calculations can be found in chapter Optical basics. Note the right angles between the line of sight and the Earth radius R0 at the. Especially in case of very small working distances of several centimetres, the calculated values are no longer realistic. This radar horizon and target visibility calculator determines the. The eNPS Calculation: Employee Net Promoter Score (eNPS) is calculated in the same way as product or brand NPS - the difference is in the question that is asked employees. The calculated working distances refer to the optic centre of the lens housing.

By means of additional spacers, however, the lens distance can be reduced ('see calculation of close-up rings'). In case of F-mount lenses and other lenses for larger image circle diameters, the minimum lens distances are often considerably larger. Hinweis: Zur einfachen Berechnung bitte einen Wert in der Dropdownbox selektieren! Eingabe eigener Werte durch Auswahl von 'User def.' in DropDown-Liste!Ĭalculating the working distance using object size and opening angleĪttention: Calculated working distances below 150 to 300 millimetres cannot be focused using normal C-mount lenses. Send your calculation with your own email program (MailTo-link).Īrbeitsabstand: mit Pixelgröße Sensor, Brennweite und Bauteilgröße rechnen Usually, flat-earth supporters run into such articles and begin to refute the calculation based on personal experience. The article, as you may have noticed, is based on the assumption that the Earth is spherical. We respect your privacy: We do not store any inputs, results or recipients. Line of sight As shown in the picture, line of sight distance is simply an addition of two prospect distances. Length/ size of inspected object in mm (field of view FOV): Note: Even when using the drop-down lists own values can be entered.
