<strong>BH</strong>2-RFL Reflected Light Fluorescence Attachment<br />
The development of new optics makes it possible to use high-energy exciting light,<br />
providing brighter fluorescence and improved results.<br />
.Three levels of exciting light intensity<br />
are available: 100%, 25% and 0%.<br />
.An aperture diaphragm allaws ttle precise<br />
regulation of exciting light intensity and<br />
fluor- image contrast.<br />
*Features a built-in field diaphragm with<br />
centering mechanism. This feature eliminates<br />
stray llgM which caw flares and<br />
reduces image clarity.<br />
*The synchronized exciting filters, dichroic<br />
mirrors and barrier fitters all move together,<br />
allowing swttch over between two wave<br />
h g b at a single touch. F i types of<br />
exciting filter sliders are available, each<br />
Wing two exciting fitters. Exciting filters<br />
come in five combinatians: U-V, B-G, U-B,<br />
Bu and UG.<br />
*Additional exciting filters and barrier filters<br />
W Y be employed.<br />

These hNo transrnittdQht fluorescence<br />
units are designed specifically for B<br />
excitation and emplay the lmtt halogen<br />
lamp in <strong><strong>BH</strong>S</strong> microscope as their light<br />
source. The secondary transmission region<br />
at about 630n m in these FtTC filters enables<br />
the observation of non-fluorescence areas<br />
under red &Meld illumination.<br />
*D Plan Apo UV Series objectives<br />
feature an apochromatic design to correct<br />
