Shielded Window Provides Optical Clarity on CRT |
|
|
.....A
manufacturer of process control instruments needed to improve
the readability of shielded CRT displays on a number of its
models. Shielded windows used on the CRTs significantly reduced
light transmission, resulting in undesirably dark screens. Some
displays were also troubled with distorted text when the mesh
in the shielded windows presented moiré pattern problems. The
solution could not add cost or reduce the current shielding
effectiveness. |

.....Chomerics
provided WIN-SHIELD Elite™ EMI shielded windows to improve CRT
readability at costs less than the previous method. The shielded
windows feature a unique wire mesh weave developed for brighter
image quality through higher light transmission. These polycarbonate
windows are fully laminated with optically matched adhesives
to reduce losses from reflection and dispersion. Their front
surfaces have a non-glare hardcoat, and a clear hardcoat is
on rear surfaces. |

.....
Together, these construction features provided great improvement
to the CRTs' optical performance. They also provided better
shielding performance, surpassing 50 dB effectiveness at 100
MHz. The shielded windows were delivered in 2 weeks at unit
costs below the original window prices. |
