This laser lens is a high permeability optical component used for as Industrial testament, Lab, DIY. They are commonly used in laser beam printers, bar code scanners and sensors. Typically, the laser diode is collimated with one lens and a second lens is used to focus the beam. Notice how an image may be formed on the back surface of the lens if the pitch is chosen appropriately. collimating objective lens. The following equation describes the refractive index distribution of a SELFOC lens: Equation 1:  Model. The index of refraction is highest in the center of the lens and decreases with radial distance from the axis.

It has high quality, high reliability, and good performance advantages for laser diode collimation. Collimators for VCSELs and VCSEL Arrays: It is relatively easy to collimate the output of a vertical cavity surface-emitting laser (VCSEL), since the output beam is usually circular and exhibits a quiet moderate beam divergence.
