  • Much like surface flatness for flat optics, spherical surface power is a measure of the deviation between the surface of the curved optic and a calibrated reference gauge, typically for a 633 nm source, unless otherwise stated. This specification is also commonly referred to as surface fit.

Features

  • Ø1/2" and Ø1" Lenses Available in SM-Threaded Mounts

  • Focal Lengths Available from 20.0 mm - 500.0 mm

Thorlabs' UV Grade Fused Silica Plano-Convex lenses, which are available in Ø1/2" and Ø1" sizes in threaded mounts, are available here with a AR V-Coating centered at 1064/532 nm deposited on both surfaces. Each size is compatible with a multitude of Thorlabs lens mounts. 

UV-grade fused silica offers high transmission in the deep UV and exhibits virtually no laser-induced fluorescence (as measured at 193 nm), making it an ideal choice for applications from the UV to the near IR. In addition, UV fused silica has better homogeneity and a lower coefficient of thermal expansion than N-BK7.

The V-coating is a multilayer, antireflective, dielectric, thin-film coating that achieves minimal reflectance over a narrow wavelength range. Reflectance rises rapidly on either side of this minimum, giving the reflectance curve a "V" shape (see Graphs tab for performance plots). When compared to broadband AR offerings, dielectric V-coats achieve lower reflectivity over a narrower bandwidth and incident angle.

With a reflectance of less than 0.25% at the specified coating wavelengths, these V-Coated lenses provide exceptional transmittance and are ideal for use with Nd:YAG (532/1064 nm) lasers, as well as applications where light is transmitted through complex optical systems. 

Plano-convex lenses have positive focal lengths and are the most popular type of lens element. They are commonly used to focus a collimated incident beam; in such cases the collimated light source should be incident on the curved surface to minimize spherical aberrations. When image quality is not critical, plano-convex lenses may be a suitable alternative.

When deciding between a plano-convex lens and a bi-convex lens, both of which cause collimated incident light to converge, it is usually preferable to choose a plano-convex lens if the desired absolute magnification is either less than 0.2 or greater than 5. Between these two values, bi-convex lenses are generally prefered.

Thorlabs also offers unmounted versions of our UV-grade fused silica lenses, either uncoated or with an AR coating for one of the following wavelength ranges: 245 - 400 nm (UV), 350 - 700 nm (-A), 650 - 1050 nm (-B), 1050 - 1700 nm (-C), or 532/1064 nm (-YAG).

V-Coating:
The V-coating is a multilayer, anti-reflective, dielectric thin-film coating designed to achieve minimal reflectance over a narrow band of wavelengths. Reflectance rises rapidly on either side of this minimum, giving the reflectance curve a “V” shape, as shown in the following performance plots. Thorlabs' V-coats have a minimum reflectance of less than 0.25% per surface and are designed for angles of incidence (AOI) between 0° and 20°. Compared to the broadband AR coatings, V-coatings achieve lower reflectance over a narrower bandwidth when used at the specified AOI.

The lenses sold on this page are also available with broadband antireflective coatings, the reflectance traces of which are shown in the graph below.

These high-performance multilayer AR coatings have an average reflectance of less than 0.5% (per surface) across the specified wavelength ranges and provide good performance for angles of incidence (AOI) between 0° and 30° (0.5 NA). The plot shown below indicates the performance of the standard coatings in this family as a function of wavelength. Broadband coatings have a typical absorption of 0.25%, which is not shown in the reflectance plots.
