The Microfilm Shop has a full range of Diazo and Silver Microfilm products including our very own Ozaphan range of Diazo including our patented M Black Diazo and the full Fujifilm range of silver microfilm products – for which Genus – The Microfilm Shop are the master European, African and Middle East distributor.
In January 2025 Fujifilm Japan announced the discontinuation of microfilm production with last orders being taken in December 2025. In America, Fujifilm USA decided to ration supplies of microfilm consumables to the USA market. Outside of North America, Fujifilm Europe allocated large volumes of microfilm consumables to Genus and The Microfilm Shop in the UK – enough for 3 years’ worth of supplies. We have therefore been supplying large volumes of Fujifilm microfilm to the USA market since June 2025, via our exclusive USA distributor, Microfilm Products Company.

A duplicating film is used to make copies of the original silver-based camera film. These duplicate films are required for off-site storage, security, distribution etc. Duplicate film is available in the same formats as the original silver halide camera film i.e.. 16mm, 35mm, 105mm in roll or A6 sheets and aperture cards.
i) Diazo Film
This is a very low cost copying medium with up to 50 years archival life. For normal commercial purposes this is the ideal economical, very hard wearing, copying medium. Diazo film is processed using ammonia gas or liquid to produce either a blue or black image from the original film.- ii) Silver Film
Silver duplicating film is available in 2 formats: – - a) Positive Print Film – to produce a duplicate that is opposite to the original (i.e. negative original changed to a positive copy).
- b) Direct Duplicate Print Film – where the duplicate is the same as the original (i.e. a negative original produces a negative copy).
Compared with diazo and vesicular duplicating film, this is a more expensive duplicating process but has exceptional image quality and an archival life of 100 years+ when filmed and stored properly. It is an ideal archival storage medium.
The Microfilm Shop offers a complete diazo, vesicular and silver duplicating service.
105 X 148mm Sheets (Microfiche) Standard Formats
Cut Corners
One corner of each diazo sheet is normally cut off. If the cut corner is positioned to the top right then the emulsion is on the reverse side of the material.
Diazo duplicating film uses ammonia to develop the film once it has been exposed. The Microfilm Shop can supply a full range of ammonia liquids and gases. Also available is absorber (DABSORBER) which is used to absorb excess ammonia during the development process thus avoiding unnecessary ammonia fumes.
Silver duplicate film requires developer and fixer.
Fiche labels are available in 127 x 11mm size (JLF) on sheets of computer stationery. These are ideal to place over old or incorrect existing headings.
Camera film or silver halide film, is the original film that is loaded into your camera when you are microfilming your documents and is therefore the basis of every microfilm system.
i) 16mm film
Held on a spool, 16mm films are usually on a 2, 4 or 5mil thick base and many lengths are available to suit particular applications. The most commonly used are 30.5m (100ft) and 61m (200ft).
ii) Specialised Cartridge films
In these applications the unexposed 16mm film is pre-loaded into a cartridge. Although this makes loading film into the camera easier it usually ties you to a single supplier. In Europe Bell and Howell’s cartridge PAK film is usually Fuji and the 3M G01 film has varied between Kodak and Agfa (and back again) over the last few years. The Microfilm Shop is able to supply both types of cartridge loaded with any of the three makes of film.
iii) 35mm film
These are usually used in 30.5m (100ft) rolls for flatbed cameras or cut into frames and mounted onto aperture card/camera cards.
iv) 105mm film
105mm film is normally cut into sheets, 105mm x 148mm, for use in a variety of microfiche cameras.
Most films are available with a choice of two types of emulsion.
- i) High Speed Emulsion
As a general rule these films are used in Rotary Cameras. This type of camera has an exposure time whose duration is dictated by the constant speed at which the camera physically transports the document past the film. Therefore, to ensure quick filming a high speed emulsion is needed. - ii) Medium Speed Emulsion
As a general rule these films are used in Flatbed Cameras. This type of camera usually controls the exposure time to suit the document and light source whilst the document lies on the camera bed without moving. Medium speed emulsions have a smaller grain size thereby tending to give better quality images at the expense of the speed of filming.
We can provide all the consumable items required for a processing department including film handling gloves, processor leaders, control strips, test wedges, self-threaders, self-adhesive processing tape and postal return bags.
Resolution Test Charts can and should be filmed onto your roll of microfilm alongside your documents. Once the film is processed the Resolution Test Charts can be viewed on the microfilm to evaluate the quality of resolution of the roll of microfilm. Resolution Test Charts are essential for high quality microfilm production. A full range of these test charts and density patches are available from The Microfilm Shop depending on your camera type.
Essential for quality control checking of the density of your finished microfilms. The Microfilm Shop can provide a complete range.
