LASER LINE BI-CONCAVE LENSES (DAR Coated)

Laser line bi-concave lenses are fundamental tools in photonics research, providing essential capabilities for manipulating laser beams, correcting optical imperfections, and enabling advanced experimental techniques. Their diverging nature makes them indispensable for beam expansion, light sheet generation, and integration into complex optical systems.

For laser applications, bi-concave lenses often feature specialized anti-reflection coatings optimized for specific laser wavelengths. These coatings minimize light loss due to reflection at the lens surfaces, maximizing transmission and preventing unwanted interference or damage from high-power lasers.
