The film scanner on the market now is roughly divided into two kinds: One: industrial laser film scanner, applicable to various industrial fields, including nuclear energy, petrochemical, aerospace, military, marine and various types of special equipment and other industries. Mainly for industrial non-destructive testing (X-ray, γ-ray photography) after the negative digital scanning. The picture shows the world's only industrial laser film scanner with an optical density of 4.7, which has passed the product certification of German BAM and is the only industrial laser film scanner that meets the international standard (ISO/EN 14096-1/2 Non-destructive testing - Qualification of radiographic film digitisation systems). The only industrial laser film scanner that meets international standards (ISO/EN 14096-1/2 Non-destructive testing - Qualification of radiographic film digitisation systems).
Two: medical film scanners, optical density can also reach 4.3. for medical X-ray film digitization. In developed countries, large hospitals generally use CR, DR, CT, and MIR, and rarely use film scanners to digitize X-ray negatives, with the only exception being the digitization of breast cancer X-ray films.
