Chrysotile Asbestos

"Darkfield image of a Chrysotile asbestos specimen in 1.550HD index mountant. You can see that the oil immersion 1.25 NA objective can be used at full resolution without a funnel stop using darkfield above 1.25 NA provided by the LOMO 1.40 NA condenser with the right size stop. I see no need for me to own a darkfield condenser, especially when none of them have a high enough NA to use with a 1.25 NA objective without a funnel stop to reduce the NA to 1.0"
