Olympus Plan Achromat Microscope Objective 10x, 0.25 NA (RMS10X)

Description

Infinity-corrected, imaging microscope objective for visible wavelengths provides 10X magnification. Used very gently in a research laboratory on a project that has since finished. The item is in perfect lik-new condition. Please do not hesitate to reach out to me with any additional questions. Direct link to the Thorlabs website from which the objective was purchased provided below. Thank you for your interest :)

When Used with a 180 mm Focal Length Tube Lens
Entrance pupil diameter (EP) is defined at the back aperture of the objective and calculated as EP=2*NA*EFL.
M = Magnification
WD = Working Distance
EFL = Effective Focal Length
NA = Numerical Aperture
EP = Entrance Pupil Diameter
OFN = Optical Field Number
PFL = Parfocal Length
