The YE0120 test chart is designed for the adjustment of camera lenses and checking back focal distance. It shows a 36 sector Siemens star on a white background.

The YE0120 test chart is designed for

  • adjustment of camera lenses
  • checking back focal distance

With the aid of a low transmission filter and by means of low level lighting make sure that the camera is not over modulated with the aperture in the open position.

a) Optical focus: Adjust focus of zoom lens at greatest focal length.

b) Back focal distance (lens): Adjust focus at shortest focal length by regulating lens mechanically with adjustment screw and optimize alternatively with a).

c) 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.
1、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.
2、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.

FAQs About Other Charts

Yes, we can offer Spectrodensitometer quality certification issued by our lab free of charge, or issued by third-party international inspection Organizations with extra charge, please contact us for confirmation.

To answer this question, you first need to clarify your specific needs: 

  • Is it for simple color quality control (QC)?

  • To coordinate with supply chain color management?

  • To monitor on-line color stability?

  • Do you require computer color matching or production color correction?

  • What is your budget?

  • Systematic supervision and evaluation of color performance in dyed products?

If you aren’t fully clear about your requirements at the initial stage, our color management engineers are ready to communicate with you. We will recommend solutions tailored to your needs. When conditions permit, we can provide prototype demonstrations and trial testing to ensure the instrument meets your practical application requirements.

There are three measuring apertures for NH310: Φ8mm (standard accessory), Φ4mm (standard accessory), extended Φ8mm (optional accessory)

a. Turning on

b. Removing measuring aperture, install the needed measuring aperture.

c. Select "Settings-Aperture Setting" in main menu to select corresponding measuring aperture.

d. After selecting aperture, the instrument will display "White and Black Calibration" interface. White and black calibration must be performed.

e. Replace completed.

a. When the colorimeter is disconnected to the PC, "Connection Timeout" will occur. At the moment, you have to check whether the USB cable is well connected the colorimeter and the PC. Then you can re-plug the USB to try out.

b. After ensuring the colorimeter is connected to the PC with USB cable, turn on the colorimeter and enter the main menu. Select "Comm" and press "Enter" key to start communication.

c. Turn off CQCS3 software, and reopen it.
