Description

ZEISS Immersol HI 661 is a high refractive index immersion oil with a refractive index of n = 1.661 (23 °C).
It has been specially developed for high-index objectives such as the α Plan-Apochromat 100×/1.57 Oil-HI Corr DIC M27 and ensures maximum resolution, optimal correction of spherical aberrations, and the highest image quality in demanding high-NA applications.

The 20 ml brown glass oiler bottle allows for precise, clean dispensing and protects the medium from light exposure.
