Aluminum Interspaced Grid
JPI grids contain the purest lead to ensure superior efficiency in removing scattered radiation.
- JPI grids contain the purest lead to ensure superior efficiency in removing scattered radiation.
- Superior quality images are achieved through the use of aluminum interspacers and lead strips, precisely milled to uniformity.
- Grid strips are sealed between smooth aluminum covers and finished with enamel, providing complete resistance to heat and moisture and guaranteeing years of trouble free service.
|Various Sizes||Manufactured to standard film sizes from 5×7″ to 14×51″. Grids for specially sized film are also available upon your request. The overall grid is one inch larger than the film size in each dimension.|
|Various Ratios||Available with ratios of 3:1 to 15:1. The ratio is the relationship between the height of the lead strips and the distance between them.|
|Focal Ranges||Available with standard focal ranges of short(26″-32), Medium(34″-44″), Long (40″ -72, 48″ -72″ and 60″ -72″) and infinity (Parallel).|
|Superior Densities||Available in Fine-line (60 pr 70 lines/inch), Micro-line (85 lines/inch), Ultra-line (103 lines/inch), Invisiable-line (150 lines/inch) and Super-invisible-line (170 or 200 lines/inch.)|
