Microfiche Scanner Inner Workings And What To Expect

By Grace Rivas





A microfiche scanner is used to scan thin transparent films that store information. The films are miniature, and the most common method of reading the films is to use the machine to magnify the film and its information. These things are commonly found in libraries and museums. Any place that is interesting in preserving documents and images would benefit from the films because they have a longer life span than digital formats do.



In case it got by you, microfilms are much more durable and stronger than digital data mediums. A small film is around 155mm x 148mm. In inches, it translates to 4 in x 5.8 in. Typically, microfilms used to embed documents and images are made from a polyester base.



Microfiches are difficult, if not, impossible to view with the naked eye. You must place the films in a scanner that will magnify and project your document for your viewing ease. The machines are basically simple scanners and projectors.



The machines are costly. They are also unique and are employed in institutions that find documentation critical to their operations. Various optical scanners can be used to convert the films data into digital format that can be interchanged between computers. When storing a large amount of microfilm, a small storage cabinet is sufficient. A small storage cabinet of microfiches can hold up to 10,000 pages of context.



While the machines are expensive, they are not complicated to use and does not require specialized software or skill to use them. Digital storage media can only be read on things like computers. Some institutions do use microfiches and digital storage media interchangeably. The polyester material which the images are printed on is quite stable, and in temperature controlled environments, the films can last as long as 500 years.



In contrast, compact discs normally do not last beyond the span of 100 years. They can, but the owner would have to operate strict control in handling and storing compact discs. Microfiches are much more reliable in terms of durability and endurance. Computer-based data devices are much more delicate, and it turns, they have a short life span. Microfiches are conservative as far as its progressive technology goes, so it is much easier to replace films when copies are damaged or lost.



Microfiches do have some disadvantages, but its advantages outweigh the disadvantages. While the need of special equipment is required, it is still bulky and unideal for everyday transportation. The films and the machines to view them are not modern day trends and are considered specialized items.



Microforms are best viewed in black and white contrast. For example, a professional photographer would not be complete in his profession using microforms and the machines for professional photography quality images. Microfilms with deep concentration in color would have fading damage over time with exposure to bright lights.



While it is possible to share files from a microfiche scanner via digital formats, it can be difficult. If one has the right equipment, it is a relatively straightforward process to set up. If a document is only available via microform, one has to travel to the physical location where a reader is to view the documents.
