Product Description
- Optical Material: N-BK7;
- Reflectivity less than 0.25% at 532nm & 1064nm;
- Applications: Beam expander, imaging, beam reducer;
- V-coating provides higher damage threshold;
The plano-convex lenses from LBTEK feature one convex surface and one flat surface, providing positive focal lengths typically used for beam reduction, focal length shortening, or imaging magnification applications. To minimize spherical aberration, when a plano-convex lens is used for focusing a collimated beam, the beam should be incident on the curved surface. When collimating a point source, the beam should be incident on the flat surface. LBTEK manufactures various lenses using N-BK7, the most common lens material widely used in visible light and near-infrared applications. The 532 nm/1064 nmV coating exhibits lower reflectivity at the operating wavelength and higher damage thresholds, making it suitable for diode lasers and applications where light passes through complex optical systems. All lenses undergo precision machining and strict quality control, ensuring LBTEK delivers high-quality optical products at competitive prices.
