Up to three of the above filters can be loaded in the filter cassette. Moving

the levers 6 on the left and right sides of the cassette to the IN position

brings the corresponding filter into the light path.

* When an IF (interference) type filter is used, flare and ghost may be

observed. These phenomena may be reduced by adding ND filter(s) to

the IF filter.

} The LBD filter is not required when the LED lamp is used.

What is LBD filter?

The color of the sun at the noon of a clear day is called the daylight

color, which looks white to human eyes. On the other hand, the

halogen bulb used as the light source of this microscope does not

emit the daylight-color light. so the LBD filter is engaged in the light

path to convert the color of halogen bulb light into daylight. In general,

engaging the LBD filter makes it possible to observe specimens in

natural color tones.
