The birefringent KCaII filter is ready for new observations

Spectral and filter observations in KCaII line play a crucial role in studying the structure and dynamics of chromospheric formations and in analyzing solar magnetism. However, most monochromatic filters for KCaII observations have a full width at half maximum (FWHM) 0.3–3 Å, whi...
