High-resolution photographic plates for holography

High-resolution photographic plates for holography

Photographic plates for holography are very different from conventional plates and films for photography. First, they tend to be sesitive (sensitized) not to the entire spectrum of white light but only to the area where the laser emits. Second, the resolution of the photographic plates for holography is very high. Below is a list of the photographic plates for holography manufactured by Slavich company.

Fields of Application       

VRP-M High-resolution photoplates for holography are designed to record holograms according to co-directed and counter-directed scheme using a continuous or pulse laser with 530 nm wavelength lasing for the purpose of non-destructive testing of equipment parts, optical data processing, for portrait and moving subjects registration.

High-resolution photographic plates for holographyPFG-01 High-resolution photoplates for holography are designed to record holograms according to co-directed and counter-directed scheme using a continuous or pulse laser with 633 nm wavelength lasing for the purpose of non-destructive testing of equipment parts, optical data processing, for portrait and moving subjects registration.

PFG-03M High-resolution photoplates for holography are designed to record counter-directed and reflectance holograms.

PFG-03C High-resolution photoplates for holography are designed to record color reflectance holograms.

PFG-04 High-resolution photoplates for holography on dichromated gelatin base are designed to record three-dimensional counter- and co-directed holograms.

Main sizes of the photographic plates (in mm) as follows:

50х50, 63х63, 76х76, 102х102, 102х127, 127х127, 90х120, 130х180, 180х240, 240х300, 300х406, 406х609 (on glass base of 2,10mm thickness) in plastic cases and cardboard boxes. According to an agreement between a customer and a manufacturer the photographic plates can be manufactured of other sizes.

Open and process the photographic plates under indirect safe light conditions with using a dark-red light-filter № 107 for VRP-M photographic plates and with using a dark-green light-filter № 170 for PFG-01, PFG-03M photographic plates.

Climate conditions for photographic plates usage: temperature of environment is (20 ± 5)оС, relative humidity of air (65 ± 15)оС.
