7. Flexible dichroic filters

We design and manufacture high-quality super thin flexible short pass and long pass filters.

Main features of flexible filters are:

  • Thickness from 30-40 μm.

  • Filter can be rolled up to a diameter of 5 mm without losing its lighting characteristics

  • Stop band blocking OD > 4

  • Pass band transparency > 85%

  • High environmental resistance

  • Operating temperature range -60 to 220 °С

Light filters on flexible substrates are indispensable for making miniature sources of non-actinic light.

For example, flexible filters are used in post lights and lamp holders of helicopters adapted for night use.
