BH2-RFL Reflected Light Fluorescence Attachment
The development of new optics makes it possible to use high-energy exciting light,
providing brighter fluorescence and improved results.
.Three levels of exciting light intensity
are available: 100%, 25% and 0%.
.An aperture diaphragm allaws ttle precise
regulation of exciting light intensity and
fluor- image contrast.
*Features a built-in field diaphragm with
centering mechanism. This feature eliminates
stray llgM which caw flares and
reduces image clarity.
*The synchronized exciting filters, dichroic
mirrors and barrier fitters all move together,
allowing swttch over between two wave
h g b at a single touch. F i types of
exciting filter sliders are available, each
Wing two exciting fitters. Exciting filters
come in five combinatians: U-V, B-G, U-B,
Bu and UG.
*Additional exciting filters and barrier filters
W Y be employed.

excitetian.
BH2-FITW
These hNo transrnittdQht fluorescence
units are designed specifically for B
excitation and emplay the lmtt halogen
lamp in BHS microscope as their light
source. The secondary transmission region
at about 630n m in these FtTC filters enables
the observation of non-fluorescence areas
under red &Meld illumination.
