IMAGELINK HD Microfilm offers high resolving power and extremely fine grain. It is ideal for filming a wide range of originals, from technical drawings to business records and historical documents.
Processing
IMAGELINK HD Microfilm is suitable for high-speed processing at high temperatures in “deep tank” microfilm processors and tabletop processors such as the IMAGELINK Archive Processor.
Spectral Sensitivity
IMAGELINK HD microfilm features a panchromatic emulsion. The absolute spectral sensitivity is equal to 1/H, with H representing the radiation energy per wavelength in mJ/m2 necessary to obtain a density of D 1.10 above the fog.
Average Sensitivity Index: 80 ASA (20 DIN)*
After measuring the incident light using an exposure meter, which is set to the given ASA/DIN value, you can adjust exposure in relation to the time/diaphragm setting of the camera. The values given are only an indication and are not related to the sensitivity index in pictorial photography.
*This value was obtained using the formula 45/H, with H representing the exposure dose needed to obtain a density of D1.2 above the fog
Unexposed film storage
The unexposed film can be kept for the length of time indicated on the packaging, provided the film is stored under normal conditions: below 22°C (72°F) with a relative humidity of 40-60%.
Cassette and camera loading
Handle unprotected film only in complete darkness. Film on camera reels can be loaded in subdued light.
Life expectancy 500
The processed film can be stored indefinitely provided it is processed and stored in accordance with relevant ISO and ANSI standards.
