BK7 Plano-Convex Lens

The BK7 plano-convex lenses are available in a variety of laser lines. We can offer laser anti-reflection coatings with different wavelengths including 405nm, 468nm, 650nm, 808nm, 980nm, 1064nm, 1319nm, and 1550nm. Designed with high light transmission rate at the specified laser wavelength, our lens is ideally used in low power Ne-He or Nd: YAG laser sources. With a maximum reflectivity of less than 0.25% per surface at the design wavelength, it is able to achieve superior light transmission through integrating with multiple optical components. Our company can offer as many as thousands of ready-made radius of curvature model. Also, we can fabricate new models according to the requirements of our customers.
