| High index planoconvex lenses can have very little aberrations for a monochromatic on axis object. This makes them ideal for focussing laser beams. Generally they are cheaper than achromatic doublets but do not perform quite as well. The higher index gives them a greater residual surface reflection unless they are AR coated. We can offer custom planoconvex lenses to meet your requirements or alternatively edge stock lenses for a quick turnaround, please enquire Specifications: | Material: | SF11 | | Diameter: | +0.0 / -0.10mm (  63mm) +0.0 / -0.15mm ( > 63mm) | | Centring Accuracy: | < 0.1mm (F.L 40mm) < 2.5mrad (F.L > 40mm) | | Focal Length: | ± 0.2% (<10mm) ± 2.0% (10-1000mm) ± 5.0% (>1000mm) | | Centre Thickness: | ± 0.35mm | | Surface Quality: | <40-20 scratch/dig | Coating: HighIndex Planoconvex Lenses are coated with Anti Reflective (SLAR) MGF2 Centred at 550nm Options available: >> Mounting (all items) >> Stock lenses can be edged to smaller diameters |
