CH3-B145 A. OUTLINE OF PRODUCT
1. Outline
CH3-BI45 is a Siedentopf type binocular tube with inclined at a viewing angle of 45” (fixed), and
combinedwith thesystemmicroscopeCH30 or CH40for educationandlaboratory, etc.,
2. Features
(1) One-sidehelicoid ring enablestheleft/right diopter difference compensation,
(2) The siedentopf type observationtube preventsthe optical path length from varying with
theinterpupillary.distance,andenhancesthedustproof andfungusproof performance.
r
f ‘
(3) It is possible to observein wide range of field number 20. (Conventional field number
was18.)
(4) The interpupillary distanceis adjustablefrom 48 mm to 75 mm, applicable to various
observer’seyes.(Conventionalrangewas53 mm to 72 mm.)
(5) The eyepieceis antitheft asit canbefixed with the clampingscrew.
3. Using Conditions
(1) Applicable frame: CH30-F,CH40-F
(2) Applicable eyepiece: WHKlOX, CWHKlOX
(3) Applicable objective: EDAch, DA+ series
(4) Usingenvironment: Temperature 0 to 40°C
Humidity 30 to 90
%
(5) Others: Fixableat anarbitrary position in anangleof 360”
(horizontal direction) only when,the interbupillary distanceis at
themaximum.

f- objective) with theBI unit installed
Revolving axis and
left/right optical axis
with sleeveinstalled
Adjust the optical axisat theabovetwo points. The internal prism position is adjustment-free
in principle.
Adjustment 0:
Adjust the revolving axisin theri$t sleeve. (“Revolving axis” meansthemechanicalrotation
center upon interpupillary distanceadjustmentand the phenomenonwhich occurs when the
optical axis is displaced. The optical axismentionedhere is the center of the sleeve. Ali@
the optica! axis with themechanicalrotation centerby changing the sleeveposition so that the
imagein the field of view doesnot moveuponobservation.)
The left sleeve is usedto adjustonly the left/right optical axis. (Align the right sleevecenter
with a point of a specimenbeforehand,then match the left sleevecenter with the point of a
specimen.)
Adjustment 0:
Almost the sameasthe adjustmentmethodperformed for installation of the BI unit of the U-
BI30.
Mount the standardobjectiveon therevolving nosepieceof adjustedframe. Mount theBI unit
with the srandard eyepieceinserted into the right sleeve on the frame. Changethe BI unit
