Thank you very much for your continuous business with us.

Regarding our product of Bräce-köhler compensator 'U-CBR1 / U-CBR2', it was identified that the orientation setting of Gamma axis (Gamma axis : direction of slow optical vibration) was different from the indication of the products when shipping. We would therefore like to replace the applicable products free of charge.

We sincerely apologize to our customers, our clients, and concerned parties for the great inconvenience caused by this issue. We will enhance our quality control system and make every effort to prevent any recurrence, and we would like to ask you for your understanding and cooperation.

[Products in scope]

Bräce-köhler compensator

  • U-CBR1 (items manufactured between 1994 and September in 2014)
  • U-CBR2 (items manufactured between 1994 and September in 2014)

U-CBR2 has the same shape as U-CBR1. The product name indicated on U-CBR2 is 'U-CBR2'
* The compensator is a phase plate to change the retardation level, which is used for the measurement of retardation.


When measuring retardation, the direction of Gamma axis for a specimen is different from the direction indicated on the instruction manual by 90 degree. As a result of this, the checked result in determining the Gamma axis for the specimen will be different from the correct result by 90 degree. This problem does not affect the operation for the purpose of retardation measurement or enhancement of contrast.
