Except for very thin trees, the error for 1 cm classes is negligible. Errors due to the observer include failure to identify breast height correctly or consistently, failure to measure perpendicular to the length axis of the tree, and varying or inconsistent contact pressure. The error due to ...
Small aspheric glass lenses can be made by molding, which allows cheap mass production. Due to their low cost and good performance, molded aspheres are commonly used in inexpensive consumer cameras, camera phones, and CD players.They are also commonly used for laser diode collimation, and for ...
