Rod Lens

https://www.lens66.com/products/rod-lens/

Rod lenses are used to focus, expand, or converge light into a single dimension. Incoming collimating light passes through the circumference of the glass rod lens to form a line. A variety of laser and imaging applications use rod lenses as line generator optics. Solar Valley uses ultra-precision CNC machining machine, the precision of the machine tool is less than 0.05 microns, the use of diamond abrasives, under the condition of precise control of the machine tool and the processing environment, to achieve ultra-precision grinding of the optical surface plastic field, and directly grind out high-precision spherical or aspherical grin rod lenses that meet the optical quality requirements. The use of ultra-high precision correction polishing technology to polish the surface of the rod lens can achieve the precision polishing of the optical surface accuracy ≤0.1 micron, surface roughness Ra≤0.01 micron.
