CK40-TBI A. OUTLINE OF PRODUCT
1. Outline
This product is a tilting binocular tube to be usedin combination with a CK 40 culture microscope
for observation in the standing position.
2. Features
(1) Since the eyepoint height can be changed from 390 mm to 465 mm (observation tube tilt
angle 30” - 60”) the best eyepoint height can be setfor individual users.
(2) At an observation tube tilt angle of 60” (eye point height: 465 mm), a standing user can
observe a specimen through the microscope in a comfortable posture.
(3) At an observation tube tilt angle of 45” (eye point height: 430 mm), the sameeye point as
IX canbe obtained.
f‘
3. Using conditions
(1) A CK40-TBI can be combined a CK40 microscope only. It cannot be combined with any
other model.
(2) In somecases,an eyepieceof field number 20 causesinsufficient peripheral light intensity
during 10X observation.
(3) A CK40-TBI cannot be combined with CK40-EPA.
(4) An infinity correction tube cannot be combined with any other UIS observation tube.
(5) In somecases,a specimenof high reflectance or high contrast produces aghost.
4. Specifications
tube can be stopped at any angle within
