Thorlabs Plano-Convex Lens Lot of 2 — LA1002-A, LA1740-A, Ø75mm N-BK7
Two large-aperture lenses that make a beam expander on their own
At 75 mm diameter these are considerably bigger than the usual 1 and 2 inch stock, and that aperture is the point. Large optics collect more, tolerate wider beams and let a focused spot stay small because the numerical aperture is higher.
The two focal lengths here, 85 mm and 150 mm, are close to a convenient ratio: put them confocally and you get a beam expander at a little under twice. Both are N-BK7 with the A antireflection coating and both are new, sealed in their original packaging.
Where it earns its place
- Beam expansion using the pair in a confocal arrangement
- Large-aperture collection from a divergent or extended source
- Wide-beam collimation where 2 inch optics clip the edges
- Building relays and imaging paths at large aperture
