Abstract
The present application relates to the field of optical lenses, and in particular, relates to a microscope objective lens suitable for use in a device such as a microscope. The microscope objective lens includes in order from an emitting side to an objective side: a first lens having a positive refractive force, a second lens having a negative refractive force, a third lens having a positive refractive force, a fourth lens having a positive refractive force, a fifth lens having a negative refractive force, and a sixth lens having a positive refractive force. The following relationship expressions are satisfied: −5.00≤R/R≤−1.50; 0.40≤WD/TTL≤0.60; 1.00≤R/((n−1)*f)≤4.00; 2.00≤d/d≤6.00. The microscope objective lens of the present application lens has excellent optical performance, low distortion, and a long working distance, which is particularly suitable for optical microscope.
