Lens systems - including those of apochromats, catadiopters or eyepieces - are traditionally optimized for the spectral range around 540nm, since this is where our eye has the highest sensitivity. Compared to the previous model with a 10nm half-band-width, this filter has a half-band-width of only 7.5nm, which increases the contrast even more.
