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.
