ABSTRACT:
An optical measuring apparatus includes an environmental chamber which has a blowing opening to which a temperature-controlled gas is supplied from an external device and an exhaust opening for exhausting the air outside the environmental chamber, a light-emitting unit for irradiating a light beam onto an object to be measured arranged in the environmental chamber, a light-receiving unit for receiving the light beam reflected by the object to be measured, and outputting a signal corresponding to a position of the object to be measured. A heat source is provided in the environmental chamber and forms an air layer having a temperature higher than the gas immediately after the gas is supplied from the blowing opening. There is provided a partitioning wall which is arranged between an optical path of the light beam and the heat source to divide a flow of the gas.
