Olympus Europa has introduced UPLSAPO30xS and UPLSAPO60xS - two new silicon oil-immersion objectives - for live cell experiments, particularly those investigating thick samples or requiring long-term imaging.
Unlike water, silicon oil is stable, viscous and of low volatility, meaning it does not dry out over time as water can.
Silicon oil does not absorb moisture from the surrounding air like glycerol, making it the medium of choice for performing reliable, reproducible long-term imaging.
Each of the new objectives features a correction collar, making it easy to reduce spherical aberration even further via simple collar adjustments, optimizing resolution, contrast and fluorescence performance.
By integrating the new UPLSAPO30xS and UPLSAPO60xS lenses into their microscopes, researchers can build a complete system, optimized for clarity, resolution and reproducibility when performing deep-tissue and long-term imaging.
Olympus said, with its 30x magnification and high NA of 1.05 the UPLSAPO30xS delivers highly resolved images of an extensive sample area.
The Olympus UPSLAPO60xS provides increased magnification (60x) and NA (1.30), allowing researchers to produce highly detailed live sample images using fluorescence, confocal laser scanning and multiphoton excitation techniques.
This objective is also ideal for high resolution 3D imaging applications by offering improved spherical aberration correction and a shorter working distance of 0.3 mm.
