Our product range contains a wide range of Spiegel Relaskop
The Spiegel-RelaskopThe Spiegel-Relaskop fulfills multiple requirements for a forestry measuring tool on a global scale. The instrument finds versatile applications in forestry as well as in science.Areas of ApplicationThe Spiegel-Relaskop is mainly used to capture the stock footprint using the angle-count sampling method to determine basal area density in forests by simple counting. Thus, the forest can be optimized for forestry or the results can be used for investigations. However, it is also possible to visually measure heights, distances, trunk diameters and gradients. It automatically corrects any inclination in the line of sight. The Spiegel-Relaskop is available in four different versions, which differ in the built-in scales. Depending on the environment and nature of the forest, the optimal scale should be chosen to successfully perform measurements.ScalesWhile the optical-mechanical function is the same for all different variations of the Spiegel-Relaskop, they differ in four scales, depending on the focus of use. A detailed comparison of the individual scales can be foundhere. MS Metric Standard, is especially suitable for forestry conditions of temperate climates with tree diameters up to 0.8 meters and for measuring heights from the standard distances of 15, 20, 25 or 30 meters. WS Wide Scale, also called virgin forest scale, is a special scale developed for the measurement of large tree diameters at different heights and for angle-count sampling with large basal-area factors. CP Metric CP, combines the functions of Metric Standard and Wide Scale. It can be used as a universal instrument for all measurements of any suitable distance with different counting factors and for precision measurements. It also has a CP correction scale to find the horizontal distance. AS American Scale, has functions analogous to the Metric Standard Scale, but the units are in American measures (feet and inches).History & BackgroundThe Spiegel-Relaskop was developed by Dr. Walter Bitterlich. Dr. Walter Bitterlich was a scientist, university professor and forester at the Austrian Federal Forests. Thanks to his research and inventions, he became the founder of the modern forest inventory. He was considered one of the most well-known personalities of the forestry and published various scientific works, among other things the angle count sampling method. This revolutionary idea prompted him to develop the Spiegel-Relaskop in 1955. Since then, it has been built in almost unchanged form and is one of the most important measuring instruments in forestry internationally. Since the beginning of 2018, the Spiegel-Relaskop has been manufactured and distributed by Silvanus.
