LEE Filters 100mm System Polyester 87C Infrared Filter is used in Black & White infra-red photography to absorb unwanted visible light up to approximately 780nm.
Light transmission then begins above 780 nanometres.
This filter is great for creating infra-red effects with both digital and film cameras.
These filters are made from a flexible high quality polyester material that is approximately 0.1mm thick.
They are supplied un-mounted by default and as such are incompatible with the standard 2mm filter slots on Lee Filters holders.
This is to allow them to be cut & shaped to fit alternative applications where a rigid resin filter would not be suitable.
If you do wish to use these filters with the 100mm System Holder then you will need to either purchase a pack of 100x100 plastic filter mounts or modify the holder with 1mm Side Blades.
