About this gig

Need a clean collimated beam from a laser diode or VCSEL, but not sure which lens to buy?


Send me the datasheet of your source and your target beam size. I will pick off-the-shelf lenses from major catalogs (Thorlabs, Edmund Optics and similar) that fit, and tell you where to place them.


What you get:

  • Recommended catalog lens with part number
  • Expected beam diameter and divergence after the lens
  • Lens-to-source distance and how sensitive it is to position error
  • A short PDF you can hand to whoever builds it

What I need from you:

  • Source datasheet (wavelength, divergence angles, emitter size)
  • Target beam size or working distance
  • Any size or budget limits

This gig covers lens selection with catalog parts. It does not include custom lens design, mechanical housing or drivers. If you need more than that, message me first and I will send a custom offer.


I am a senior optical engineer working in the laser and precision optics industry, using Zemax OpticStudio, Code V and LightTools.
