courtaulds_filters

Format

A vector of character strings.

Details

1) Films (0.115 mm thick) stretched 25 cm below Q-Panel UVB313 lamps and exposed to UV radiation from different lengths of time per day. All films were installed and sampled at the same time inside a greenhouse. The digits give the number of minutes per day that the lamps were on.

2) New films of different thickness.

Note

Individual measurements of single samples, not a specification. Instrument used: Hewlett-Packard 8453 diode array spectrophotometer without an integrating sphere. These films are no longer available, but similar material from other suppliers may be still available.
