AX-REXBA*

The use of a dual-band filter allows

simultaneous observation of double-

stained specimens. With the

conventional observation method,

photomicrography or image

documentation with optimally

balanced light intensity is difficult

since one of the two fluorochromes

may emit fluorescence that is too

weak or too strong. However, by

simply turning the dial of the AX-

REXBA, easy control of the

fluorescence balance is assured for

photomicrography with ideally

balanced light.

U.S. patent pending.

(1) Use of a dual-band filter, allows

observation of and photomicrography

with a double-stained fluorescing

specimen under optimum conditions,

regardless of the conditions of the

stained specimen.

(2) As the AX-REXBA allows

adjustment of excitation light,

unnecessary irradiation is prevented

and damage to the specimen is

minimized.

(3) The 25EBFB/G filter

accommodates a double-stained

fluorescing specimen using two types

of fluorochromes – FITC/TRITC and

FITC/Texas Red. This filter is

designed for general use with double-

stained specimens with G/B

excitation. The 25EBFU/B** filter

designed for U/B excitation is also

available.

To be released October 1997.

(4) With single-band excitation, the

AX-REXBA can serve as a continuous

light control unit. (When 25EBFB/G is

used, the AX-REXBA is applicable for

B or G excitation).

(5) The AX-REXBA is easily installed

into the AX70's aperture stop position.
