Which limitation arises when coating optics using interference?

💡 Explanation

Narrow achieved bandwidth arises in multilayer coatings because thin-film interference dictates that specific wavelengths constructively interfere, resulting in high reflection only over a limited spectral range. Therefore, the filter works for that band, rather than offering broad achromatic performance.
