CaF2 plane-concave lens D12.7* 2.5R-10.8F: 25type: 3 (0.5) C: < 3 ', no coating
These Plano-Concave lenses are fabricated from RoHS-compliant N-BK7 glass. N-BK7 is one of the most common types of 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. However, for particularly harsh environments where the optic will be exposed to alkalis and acids, consider our N-SF11 plano-concave lenses. Since the Abbe Number of N-SF11 (25.76) is lower than that for N-BK7 (64.17), lenses fabricated from N-SF11 will exhibit higher dispersion than those fabricated from N-BK7.
N-BK7 lens kits are also available. Please click here for
information.These lenses, like all plano-concave lenses, have
negative focal lengths and can be used to diverge collimated beams.
In this case, the curved surface of the lens should face the source
to minimize spherical aberration. In addition, they can be employed
to offset the effects of spherical aberration caused by other
lenses in an optical system.
Map optics technology provides uncoated, coated anti - reflection
film of Plano-Concave Lenses sheet.
Anti-reflection membrane options include UV, VIS, NIR, and SWIR.
Germanium, silicon, or zinc selenide substrates are suitable for
infrared applications, while fused quartz is suitable for uv
applications.

FAQ
A: Optical lens,mirrors,windows,filters,prisms
A: In general delivery time is about one month for custom produced optics.except stock ones or some special optics.
A: We can provide free samples if we have stock optics as your request,while custom produced samples are not free.
MOQ is 10pcs for most of the optics, while MOQ could be only one piece if you need a element in big dimention.
