Product Description
SineImage YE0110 SECTOR STAR TEST CHART (36 SECTORS)
| Material | Film or HD photographic paper |
The test chart consists of 9 sector stars, distributed equally over the picture area. The unresolved center of the sector star is 10% of its outer diameter. Within the sector stars are two circular lines. The inner one marks a 625 line structure, the larger circular line marks a structure of 312 lines.
The test chart is designed for
·adjustment of camera lenses
·checking back focal distance
·checking resolution over the picture area

With the aid of a low transmission filter and by means of low level lighting make sure that the camera is not overmodulated with the aperture in the open position.
Optical focus: Adjust focus zoom lens at greatest focal length.
Back focus distance (lens): Adjust focus at shortest focal length by regulating lens mechanically with adjustment screw and optimize alternatively with a).
Back focal distance (pick-up tubes): If focus varies from channel to channel between greatest and shortest focal length, the individual pick-up tubes must be adjusted mechanically in the optical axis.
Select white channel. Set optical focus at greatest focal length. With shortest focal length and divergent focus adjust the pick-up tube in W-channel until optimum focus is achieved. If necessary optimize by alternating with optical focus adjustment.
With unchanged optical focus adjustment and shortest focal length adjust the red and blue pick-up tube until optimum focus is achieved. Image focus (focus adjustment) is maintained at all focal lengths (zoom-in) and constant distance from object by means of back focal distance adjustment.
