Field: Optics (Instruments)
Classification: CPC G  H | IPC G  H

Claim 0:
1. A microlens comprising:
a first side;
a second side opposite to the first side;
a first lens layer having a first aspheric-surface shape provided on the first side; and
a second lens layer having a second aspheric-surface shape provided on the second side,
wherein the microlens is configured to deliver a wavelength range of 1290 nm to 1610 nm,
wherein a working distance (WD) is 0.160±0.05 mm, and a beam divergence angle is less than 1 mrad by satisfying Equation 1:

R1/R2=1.8 to 3.5  [Equation 1]

where R1 is a curvature radius of the first lens layer, and R2 is a curvature radius of the second lens layer.
