Abstract:
An extreme ultraviolet light sensor unit according to one aspect of the present disclosure includes a mirror configured to reflect extreme ultraviolet light, a filter configured to transmit the extreme ultraviolet light reflected by the mirror, an optical sensor configured to detect the extreme ultraviolet light having passed through the filter, a purge gas supply unit disposed to supply purge gas to a space between the mirror and the filter, and a pipe part configured to allow plasma light including the extreme ultraviolet light entering from an opening to pass therethrough toward the mirror and allow the purge gas flowing to the space between the mirror and the filter to flow out of the opening.

Claim (Index 5):
The extreme ultraviolet light sensor unit according to  claim 1 , wherein\n the purge gas supply unit is disposed to allow the purge gas to flow to the space between the mirror and the filter, from a second optical path among a first optical path and the second optical path, the first optical path being an optical path for the plasma light to be made incident on the mirror from the opening while passing through the pipe part, and the second optical path being an optical path on which the extreme ultraviolet light reflected by the mirror travels toward the filter.
