CFI Plan Apo Lambda S 25XC Silicone Immersion Objective

The Nikon CFI SR HP Plan Apochromat Lambda S 25X is a premium silicone immersion objective engineered for super-resolution microscopy and deep tissue imaging at mid-magnification. As part of Nikon's SR HP (Super-Resolution High Performance) Lambda S series, this objective combines apochromatic correction with silicone immersion technology, delivering exceptional optical performance for imaging thick specimens at depth. The silicone immersion medium (refractive index ~1.40) closely matches the refractive index of biological specimens, dramatically reducing spherical aberration when imaging deep into thick samples compared to oil or water immersion. With a high numerical aperture of 1.05, this objective provides outstanding resolution and light-gathering efficiency for super-resolution techniques and detailed cellular imaging in thick specimens. The Lambda S designation signifies Nikon's advanced optical design optimized for extended spectral range and superior flatness of field. The 0.55mm working distance provides excellent clearance for imaging into thick specimens, making it ideal for deep tissue applications. Compatible with Nikon's CFI infinity optical system, this objective integrates seamlessly with Eclipse Ti2, Ni-E, and A1 series research microscopes, making it essential for laboratories conducting super-resolution microscopy, 3D cell culture imaging, organoid research, and thick tissue imaging at mid-magnification. This objective is in new condition.
