Patent abstract
A target for a surveying instrument, which receives from the surveying instrument a laser point light indicating a position and a distance measuring light to measure a distance, comprising a reflection diffusion layer for reflecting and diffusing the distance measuring light, a wavelength filter layer for selectively transmitting the laser point light passing through the reflection diffusion layer, and a transmission diffusion layer for spreading in a given direction and for transmitting the laser point light passing through the wavelength filter layer, wherein a projecting position of the laser point light can be confirmed.
