【Guidance on Selecting Your Olympus Objective】
When making a purchase, please consider the following crucial factors to ensure perfect compatibility with your existing microscope system:
Infinity Correction: Most modern Olympus microscopes (e.g., BX and IX series) utilize the Universal Infinity System (UIS/UIS2). Ensure the objective’s labeling matches your system.
Numerical Aperture (N.A.): The NA value is critical for determining resolution and brightness. A higher NA means sharper details and better light collection.
Working Distance (W.D.): Pay close attention to the working distance, especially if your application involves live-cell imaging or complex manipulation.
