Quantum Calcium II H 5Å PE magnesium fully baffled 2 element telecentricDaystar is proud to offer Calcium H ( 3969 ) and two Calcium K line (3933. 7 ) filtering systems. Traditionally, university research has employed the Calcium K line for studies of Calcium on the Sun. These studies have been instrumental in determining depth of the solar atmosphere. Calcium offers TWO strong absorption lines at 393. 3nm and at 396. 9nm, known as the K and H lines. Researchers have previously avoided the H line for academic research, as
