# Description and specifications:
- Part: "0" Disc with Phase Contrast Ring
- Compatible with 10x objective lenses
- Accepts the following phase objectives: Ph (Zernike, green band), PhA (negative, anoptral, yellow band*), PhS (positive, gray band), and A (amplitude phase contrast, brown band).
- Position: Can be screwed into any position on the PZO KFL condenser

The PZO KFL condenser is a universal microscope condenser with interchangeable discs. It can be fitted with both phase contrast and darkfield discs (which can be mixed). Each disc is focused to perfectly match the microscope objective. PZO KFL = "Fluorescence Contrast" is an accessory to the PZO fluorescence kit and was originally sold with the PZO Biolar FL and PZO MB30 FL microscopes, among others. It can be used with any microscope from any manufacturer that accepts a 39.5 mm condenser, although the top lens can be replaced with a 37 mm lens.

*Note: The yellow stripe on PZO PhA phase contrast objectives sometimes turns orange over time.

# Examples of use
- if you have a PZO KFL condenser that is missing this phase disc
- if you have a PZO KFL condenser equipped with darkfield discs and want to use phase contrast with a 10x objective
- if the disc in your condenser is damaged (e.g., scratched)
- if you want this item as a spare part
