The customer asked about the screen

On May 4, I received a call from a customer who wanted to buy a batch of filter grids to filter the excess light of their equipment. The customer did not understand the specific value and utility of the filter grids, so he explained the specific situation of the filter grids to the customer.

There are three important parameters of the grid, which are size, grid ratio and focal length. The sizes are


9X11 (23X28cm)

11X13 (28X33cm)

12X15 (30X38cm)

13X16 (33X40cm)

15X15 (38X38cm)

15X18 (38X46cm)

18X18 (46X46cm)

Grid ratio 8:1 10:1 12:1 focal length 0.7-1.8m optional

The size of filter grid and other parameters can be customized. The conventional gate density can be 40L / cm (103l / in), 52L / cm (130L / in) and 60L / cm (150L / in).

Newheek filter grid is composed of lead foil (i.e. thin lead strip with thickness of 0.05-0.1mm) arranged at a certain distance (0.15-0.35mm) according to the phase parallel or a certain slope. The lead strips are filled and fixed with aluminum, paper or wood strips that can pass X-ray, and both sides are supplemented with aluminum or synthetic resin protective layer.

Specific function: “the filter grid is used to filter out the influence of scattered rays on the film, which should be placed between the human body and the film. Most of the scattered lines can be filtered out, and only a small part of the scattered lines can be missed.”. Classification: according to the structure: 1 convergence grid: each lead bar inclines to the focus, i.e. the lead bar extension line is concentrated in the focus parallel grid: each lead bar is parallel to each other in the vertical plane 3 cross grid: it is composed of two layers of parallel grid, the lead bar direction is 90 ° arc grid: it is composed of equal radius from the center to the outside, Tile shape, the above is about the filter grid, interested friends can call 15628738102
