2.3d Color Filters

[image: filter holder with filter]

32mm filters can be used with this microscope to alter the color of light. Common filters include green, yellow, and blue.

A green filter is commonly used to concentrate light in the middle of the spectrum, as most optics are designed to pro-

duce optimal results using these center wavelengths. Blue filters can be used to compensate for light sources with warm-

er color, or to better image certain specimens. Yellow filters can be used with cooler light sources like LED to decrease

higher-intensity wavelengths which can fatigue the eyes over long periods.

The condenser is equipped with a filter-holder located on its bottom. The holder has a small peg which can be pulled in

a clockwise motion to swing the holder outward. The condenser may need to be rotated to allow the space needed to

open the holder. Once the holder has been fully opened, a 32mm filter can be placed within the holder's recess. Close

the holder to engage the filter.
