Live Cell Imaging Silicone Immersion Objectives and the FV3000/ IXplore
Silicone Immersion Objectives
Silicone immersion objectives are optimized for live cell and live tissue imaging. With a refractive index similar to that of living tissue, silicone immersion objectives offer bright images of cleared tissue. And because silicone oil doesn’t dry out at 37 °C (98.6 °F), time−lapse observations are more reliable and less complex.


Effects of Refractive Index Mismatch on Sample Shape
Matching the refractive index of a sample and immersion media is very important to get accurate 3D images.
The Brightness of Water/Silicone/Oil 60X Objectives
Oil immersion objectives are the brightest at superficial depths while silicone immersion objectives are brighter than water and oil immersion objectives at all other focus depths.
The brightness of each objective is normalized to the 60X oil objective at the sample’s surface. The sample's refractive index is 1.38.
