Product Info
EL-10-42-OF-NIR and EL-10-42-OF-532
The electrically focus-tunable lens EL-10-42-OF with integrated proprietary optical feedback (OF) is dedicated to 2.5D and 3D laser applications. It sets the highest standards in terms of spot quality and speed.
With a focus tuning range of -2.0 to +2.0 diopters, a constant laser spot can be controlled over a large range along the z-axis (up to 250mm), with a long term repeatability of <0,02 dpt.
The EL-10-42-OF comes in two versions, one designed for use in the NIR (950-1100nm) up to 50 W, the other for the visible (532 nm) up to 20 W.
Applications
Optotune's EL-10-42-OF is the ideal choice for a range of laser applications where reliable beam focusing in 3D volumes is a must:
Laser marking and engraving
Laser cleaning, welding, drilling
Micromachining
Medical, Ophthalmology (OCT)
3D-printing, additive manufacturing
Laser projection templating
