摘要
A laser transmitter adapted for use in small spaces such as pipes and sewers includes a housing having two exit windows positioned in generally orthogonal planes. The laser transmitter includes a leveling mechanism that is capable of directing a collimated beam through a select one of the two exit windows, in a generally horizontal direction at a specified grade irrespective of whether the laser transmitter is oriented generally horizontally or generally vertically.
