LUPLAPO25XS Multi-Immersion Silicone Gel Pad Objective
The LUPLAPO25XS is a 25X, NA 0.85 multi-immersion objective designed for deep imaging of organoids, 3D cell cultures, and multi-well plates. It supports water, silicone oil, and silicone gel pad immersion, offering up to 2 mm working distance (1 mm with gel pad) and a 26.5 mm field number.
The silicone gel pad matches the refractive index of living tissue, enabling deeper signal penetration and more accurate 3D morphology imaging without liquid immersion. The gel pad moves with the objective, simplifies well plate navigation, eliminates reapplication steps, and provides stable conditions for time-lapse experiments.

Key specifications:
• Magnification: 25X
• Numerical aperture: 0.85
• Working distance: 2 mm (water, silicone oil), 1 mm (gel pad)
• Cover glass thickness: 0.13 to 0.19 mm
• Chromatic correction: APO (silicone oil and gel pad)
• Gel mechanical properties: flexible, durable, low adhesion to containers; returns to original shape after thousands of uses; continuous usable period around one month under normal conditions
• Stability & safety: resistant to moisture and heat; properties stable over long periods with no expiration date; manufactured in high-class cleanroom for low contamination and bubble-free gels
• Operational support: cellSens™ software control for automated gel-pad escape and recontact during XY movement to enable multipoint acquisition without image quality loss; stage navigator visualizes observable range for gel immersion
