Thorlabs' UVFS plano-concave lenses diverge a collimated beam from a virtual focus and are commonly used in Galilean-type beam expanders. Plano-concave lenses have a negative focal length and negative spherical aberration, which can be used to balance ou
Thorlabs' Mounted Plano-Convex Round Cylindrical Lenses focus or collimate light along a single axis. The lenses sold on this page are fabricated from a zinc selenide (ZnSe) substrate that provides high transmission throughout the mid-IR spectral region, as shown on the Graphs tab. They are av...
Thorlabs' Ø1/2 and Ø1 Silicon (Si) Plano-Convex Lenses are available with a broadband AR coating optimized for the 2 µm to 5 μm spectral range deposited on both surfaces. This coating greatly reduces the surface reflectance of the substrate, yi
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. ...
where n is the index of refraction and R is the radius of curvature of the lens surface. These lenses are fabricated from N-BK7, which has an Abbe Number of 64.17; this value is an indicator of the dispersion.These N-BK7 Plano-Convex lenses are also available with one of five ...
These Plano-Convex Lenses are fabricated from RoHS-compliant N-BK7 glass and feature an antireflection coating for the 650 nm to 1050 nm range. N-BK7 is typically chosen whenever the additional benefits of UV fused silica (i.e., good transmission further
These Plano-Convex Lenses are fabricated from RoHS-compliant N-BK7 glass and feature an antireflection coating for the 1050 nm to 1700 nm range. N-BK7 is typically chosen whenever the additional benefits of UV fused silica (i.e., good transmission furthe
These Plano-Convex Lenses are fabricated from RoHS-compliant N-BK7 and feature an antireflection (AR) coating that provides <1.0% average reflectance per surface over the 400 nm to 1100 nm wavelength range. N-BK7 is typically chosen whenever the additional benefits of UV fused silica (i.e.,...
