Product details

Our N-BK7 plano-convex lenses are polished to great tolerance with master test plates to ensure minimum wave front distortion for demanding electro-optic focusing purpose. N-BK7 is a great lens material for most visible applications. N-BK7 is the most common crown optical material, it provides good performance at a good value. Our single layer Magnesium fluoride AR coating is a common coating that offers an extremely broad visible wavelength range at a reasonable price. Compared to the uncoated surface, the MgF2 coating provides a significant improvement by reducing the reflectance to less than 1.5%. Broadband multilayer AR coating is also available, 350-650nm, 400-700nm and 650-1050nm.

Custom capabilities:
Diameter range: 3mm to 750mm
Tolerance: +/-0.04mm
Scratch-dig: 40-20 or 20-10
Surface accuracy: Lambda/2
Focal length tolerance: +/-1%
Bevel: 0-0.5mm
Coating: Single layer MgF2, Broadband anti-reflection coating.

For custom made lenses, please send us drawings.

Select plano-convex lenses guide.
Plano-convex lenses are the best choice for focusing parallel rays of light to a single point, or a single line in the case of cylindrical lenses. These lenses can be used to focus, collect and collimate the light. The optimum case is where the object is placed at infinity and the final image is a focused point. Although infinite conjugate ratio is optimum, plano-convex lenses will still minimize spherical aberration up to 5:1 conjugate ratio. For the best performance, the curved surface should face the largest object distance or the infinite conjugate to reduce spherical aberration.
