Spherical mirrors are easier to manufacture but introduce spherical aberration at off-axis angles, suitable for low-resolution systems. Parabolic mirrors eliminate spherical aberration completely, providing superior image quality for high-resolution spectrometers but require precise alignment.
With proper handling in controlled environments, focusing mirrors typically require cleaning every 6-12 months using approved optical cleaning procedures. Replacement is only necessary if surface damage, coating degradation, or permanent contamination occurs, which can happen after 3-5 years of continuous use.
