Laser Material ProcessingLaser Cutting & Welding: These lenses focus high-power laser beams into micron-scale spots for precise material ablation. Orienting the flat surface toward the laser minimizes energy loss. Illumination EngineeringProjectors & Fiber Optic Couplers: Plano-convex lenses collimate light from LEDs or fiber outputs to ensure uniform illumination. Solar Simulators: Used to focus sunlight onto photovoltaic cells for efficiency testing. FAQOptical Plano Convex LensQ: Which surface should face the collimated light source?A: For optimal performance, the convex surface should face the collimated light. This minimizes spherical aberration, especially in infinite conjugate setups.Q: What is the maximum power handling capability?A:N-BK7 lenses with AR coatings: up to 10 W/cm2 (CW) in visible wavelengths.Fused silica lenses: withstand >100 W/cm2, suitable for high-power lasers. Q: How does temperature affect focal length?A:N-BK7: Moderate thermal expansion (7.1×10-6/°C). Fused silica: Superior thermal stability (0.55×10-6/°C), ideal for high-precision, temperature-varying environments. Q: Can these lenses be used for fluorescence microscopy?A: Yes. Fused silica plano-convex lenses with UV-AR coatings are excellent for fluorescence applications, transmitting both UV excitation and visible emission wavelengths.InspectionsProduction LineCompany HistoryCertifications
