When an in-line filter is needed, we offer two types of in-line filter holders - the FH-INL-1” and the FH-INL.

 

The FH-INL-1” is designed to hold one inch filters from 1-60 mm thick. The FH-INL is designed for 1/2” or 12-13mm filters of 1-8mm thick.

​

Both in-line filter holders come with two quartz collimating lenses for the UV/VIS/NIR range. We also offers a wide range of round 12mm filters (for FH-INL). For more specifications please see the table below.
