A wide range of accessories to enable different kinds of

fluorescence imaging.

Fluorescence illumination light source

Bright excitation illumination for cell observation/manipulation

The Olympus lineup for fluorescence illumination equipment meets a wide variety of needs

including multi-color fluorescence, ratio imaging, photobleaching and uncaging observa-

tions. The brightness at low magnification is greatly improved.

*1: Can collect light more efficiently than conventional aspherical optics.

*2: Even illumination and no lamp focusing shift, even when changing excitation light wavelengths.

*3: Suitable for multi-color staining or ratio imaging because of flat light source spectrum.

Reflected light fluorescence illuminators

[ L-shaped fluorescence illuminator/IX2-RFAL ]

Provides easy access to burner centration

and removable aperture and field stops.

The L-shaped design maintains access to

both back frame ports.

[ Double lamphouse illuminator/IX2-RFAW ]

Two light sources can be used

simultaneously, so that light stimulation can

be performed during observation.

[ Double lamp housing adapter/U-DULHA ]

Allows simultaneous attachment of two light

sources such as halogen and mercury.

Selection mirror

is replaceable

for custom

applications.

Configuration example

Illumination modular units

[ Rectangular field stop/U-RFSS ]

This unique field stop allows the user to control the area of

fluorescence excitation anywhere inside the visual field. For

example, photobleaching and phototoxicity can now be limited to

only the area that is being imaged by the CCD improving overall

brightness and cell viability over long term observations. The unit is

attached at the field stop position of the fluorescence illuminator

IX2-RFAL.

[ Pinhole field stop/IX2-RFSPOT ]

Flexible field stop options IX2-RFSPOT pinhole field stop module

can be mounted in the L-shaped illuminator for photobleaching

experiments.

IR camera adapters

[ C mount camera adapters/U-TV0.35XC-2, U-TV0.5XC-3,

U-TV0.63XC, U-TV1X-2 , U-TV1XC]

These low-magnification camera adapters cover from visible light to

near infrared red wavelength spectrum. U-TV0.35XC-2,

U-TV0.5XC-3, U-TV0.63XC and U-TV1X-2 are attached to the left

side port.
