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.

Features of Rod Lens

One-stop customized production: Solar Valley processes a variety of diameter and length of rod lenses according to customer requirements.

Material: The use of optical quartz, optical glass, sapphire and other materials.

Rod lens performance: Grin rod lens focuses the incident light into a line, or changes the aspect ratio of the image. A rod lens has a single cylindrical surface that focuses incoming light on only a single dimension, thus stretching the image. Rod lenses can provide positive or negative focal lengths and are suitable for laser line generation or deformed beam shaping.
