Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If dedicated interferometer measuring instruments
Chapter note 5 prioritizes measuring instrument classification over general optics.
If specifically for lasers (not interferometers)
Laser parts have separate provisions from other optical appliances.
If general mirror adjustment mechanisms
Multi-purpose adjustment parts default to 9033 catch-all.
