Product Description

l Substrate: CaF2

l Operating Wavelength: 200 nm-8 μm (uncoated)

l Application: Imaging, beam expansion or reduction, convergence

     Plano-convex lenses have one convex surface and one flat surface, and have a positive focal length. They are typically used in applications such as beam reduction, focal length reduction, or image magnification. To reduce spherical aberration, when a plano-convex lens is used to focus a collimated beam, the beam should be incident on the curved surface of the lens; when used to collimate a point light source, the beam should be incident on a flat surface. Tuniu uses CaF2 to manufacture a variety of lenses. CaF2 has high transmittance in the ultraviolet and infrared spectral ranges and an extremely high damage threshold, making it widely used in the excimer laser industry. CaF2 material has a low refractive index, ranging from 1.35 to 1.51 in the operating range of 180 nm-8.0 µm. CaF2 is also very chemically inert compared to similar materials such as barium fluoride and magnesium fluoride. It also has high hardness characteristics. It is an ideal choice for lenses used in the ultraviolet and infrared bands. Our lenses are carefully processed and strictly controlled to ensure that Tuniu can provide users with high-quality lens products at reasonable prices.

Attributes

Plano-Convex (PCX) Lenses, CaF2, Uncoated: 200 nm-8.0 μm, Mounted or Unmounted

     Plano-convex lenses are commonly used in applications such as beam reduction, focal length reduction, or image magnification. Tuniu offers various lenses using CaF2, which exhibits high transmittance in both ultraviolet and infrared spectral ranges, along with an extremely high damage threshold, making it widely applicable in the excimer laser industry. All circular lenses from Tuniu can be mounted in Tuniu standard lens tubes, fixed lens mounts, and various coaxial mounting plates. The surface of these mechanical parts is engraved with the product model, type, diameter and focal length, making it easy for users to quickly identify lens parameters.
