Nikon S Fluor 4x/.20 M25 Thread Size Microscope Objective

Nikon S Fluor 4x/0.20 Objective – Refurbished/Used

The Nikon S Fluor 4x/0.20 (Model: MRF00040) is a high-performance objective designed to provide excellent contrast, resolution, and light transmission at low magnification. As part of Nikon's Super Fluor series, it offers superior correction for spherical and chromatic aberrations, making it ideal for fluorescence, brightfield, and transmitted light microscopy.

With a numerical aperture of 0.20 and an M25 thread mount, this objective is compatible with modern Nikon Eclipse microscope systems and delivers outstanding image quality across the field of view. Its high transmission and fluorite optics make it especially suited for applications that benefit from widefield fluorescence at low magnification.
