The ESK52-B is a lens set containing 57 AR-coated plano-convex lenses (LA Series) and 44 AR-coated bi-convex lenses (LB Series). Click on the Complete Product Details link above to see a list of the exact lenses included in this kit.
These lenses are fabricated from RoHS-compliant BK7 glass (N-BK7). N-BK7 is probably the most common optical glass used for high quality optical components. It is typically chosen whenever the additional benefits of UV fused silica (i.e., good transmission further into the UV and a lower coefficient of thermal expansion) are not necessary.
