- Product Description
- Additional Information
- "Dry" darkfield condenser for our T490 compound microscopes "Oil" darkfield condenser included
- Improved contrast in translucent specimens
- 100X objective with iris included
- Designed for lower & higher NA objectives
This is a darkfield condenser set for our 490 series compound microscopes, designed for dry use with lower magnifications, and for oil use with higher magnifications. The dry condenser will accommodate lower-magnification objective lenses with numerical apertures lower than 1.0, and the oil condenser up to 1.36 NA. A plan 100X objective with its own iris is included for optimal image quality at high darkfield magnification levels.
The darkfield condenser uses principles of light-diffraction to suppress field-illumination, while illuminating the edges of otherwise-transparent or translucent objects. This is particularly useful for quantitative analysis of low-contrast specimens.
