When an in-line filter is needed, Avantes offers two types of in-line filter holders: the FH-INLINE-1” and the FH-INLINE. The FH-INLINE-1” is designed to hold one inch filters from 1-60 mm thick. The FH-INLINE is designed for 1/2” or 12-13 mm filters of 1-8 mm thick.

Both in-line filter holders come with two quartz collimating lenses for the UV/VIS/NIR range. Avantes offers a wide range of round 12 mm filters (for FH-INLINE).
