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.

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.
