Cylindrical lenses focus or expand light in one axis. The orientation, EFL, clear aperture and line uniformity matter more than the catalog shape. Send the beam size, working distance and required line length so the lens and mount can be reviewed together.
- Laser line generation
- Beam shaping
- Astigmatic correction
- Plano-convex or plano-concave
- N-BK7 / UVFS options
- AR coating
