Blocking >OD6,0
(0,0001%) Available
Limited materials for
UV or IR designs
Easy to handle and clean More limited selection
transmission and blocking Very angular sensitive
Insensitive to
angle of incidence
Since light is absorbed, can be damaged
by high heat or laser power
Many bandpass, edge,
dichroic, and neutral density
options to choose from
Coatings can be damaged
by cleaning or handling
Many bandpass, edge,
and dichroic designs
to choose from
Coating costs scale considerably
with size and complexity
