Excel Precision manufactures the 1160A Weather Station and 1024A Refractometer for laser wavelength compensation.
Are you worried about air turbulence affecting your ultra-precision machine alignment accuracy? Are you worried about local heat sources affecting the stage accuracy? Are you worried about light absorption affecting the stepper lens working depth of focus?
Excel Precision’s patented Weather Station can assist you in resolving these problems!
The 1160A Weather Station is an electronic device that measures temperature, relative humidity, and barometric pressure in real-time. It is very compact, and can be mounted on top of the plane mirror interferometer, or on the moving X-Y stage. For more accurate position measurements, one 1161A Sensor Head can be attached to each axis of the interferometer.
The physical dimensions for the 1161A Sensor Head is very compact in that it can be mounted at the proximity of the measurement path and accomplish best laser wavelength compensation. For maximum accurate position measurement, one 1161A Sensor Head can be attached to each axis of the interferometer.
The 1161A Sensor Head can be attached to 1065 Signal Processor and readily be used after configuration via GUI (graphic user interface). The 1161A Sensor Head measures temperature, relative humidity, and barometric pressure with an updated rate of one minute.
