F2, H-K9L Optical Glass Rod Lens D5-10*L20-40mm
The F2 and H-K9L Optical Glass Rod Lens is a high-precision cylindrical lens designed for efficient light focusing, collimation, and beam shaping in compact optical systems. Manufactured from premium F2 or H-K9L optical glass, it offers excellent optical homogeneity and reliable performance. The lens features a diameter range of 5–10 mm and a length of 20–40 mm, with customizable dimensions available. Both surfaces are precision-finished to 60/40 scratch-dig and coated with a multi-layer AR coating, achieving R ≤ 0.2% at 480–643 nm for minimal reflection loss and high transmission.

Optical Rod Lenses focus laser beams into a uniform straight line for high-precision imaging and laser processing applications.
Homogeneous type: Uses a polished cylindrical surface to generate a linear spot. Ideal for laser marking, barcode scanning, and laser measurement.
GRIN type: Features a radially varying refractive index for smooth light bending. Ideal for contact image sensors in printers and scanners.
