About AbbeTrex LLC

I couldn't find the Abbe diagram I wanted, so I made one and am here to share it and other useful tools with you.

How It Started

AbbeTrex was born in October 2025 from a single Reddit post that wouldn't leave my mind. Over on r/Optics, a user shared a spinning Abbe diagram generated by sweeping the reference wavelength range. After seeing how the glasses rotated around in that post, I searched for a manufacturer's Abbe diagram that would let you choose a custom wavelength range. I couldn't find one - every Abbe diagram was for the visible spectrum.

So I built an abbe diagram website from scratch! The first version read from a single Schott catalog CSV file and reloaded the entire page after every change. It was rough, but it worked. Now we use real databases and have so many more features that I'm excited about!

Where It Is Now

Today, AbbeTrex LLC has grown far beyond that first prototype. I keep having neat ideas of things to add next, but here's what's on AbbeTrex now:

  • Interactive Abbe Diagram - Explore refractive index vs. Abbe number with fully customizable wavelength ranges.
  • Glass Catalog & Comparison - A large catalog of optical materials from manufacturers worldwide, with side-by-side comparison tools.
  • Achromat Builder - Design achromatic lenses by selecting chromatically complementary glasses.
  • Partial Dispersion 3D - Visualize partial dispersion relationships in three dimensions.
  • Blog - Articles on optical engineering, glass selection, and what's new on AbbeTrex. It's a little bit of a work in progress, but let me know what you want to hear about!
  • User accounts - Save preferences, track favorites, and get the most out of the platform.

And there's plenty more in the pipeline. I'm looking forward to sharing what I have planned - check out the Welcome to AbbeTrex blog post for a look at what's coming, and follow the blog for ongoing updates.

About Me

Morgan Trexler

Optomechanical Engineer

My path to photonics has been roundabout. In high school, I got hooked on 3D printing. At the Colorado School of Mines, I looked for opportunities to research 3D printing and ended up spending three and a half years developing feedback systems for laser powder bed fusion metal 3D printers with Jeff Squier.

My experiences with laser systems under Jeff's mentorship opened doors across the photonics industry. I interned at Advanced Thin Films, developing an assembly robot for laser satellite communications systems, and at Meadowlark Optics, working on arbitrary-wavelength recalibration of spatial light modulators (SLMs), design-for-manufacturing housing revisions, and development of a solderless indium tin oxide (ITO) connection for liquid crystal variable retarders (LCVRs).

Now as my day job, I work at Momentum Optics developing novel techniques for freeform lens fabrication. If you need a custom freeform optic please reach out! I build AbbeTrex LLC on the side to give the optics community the tools I find myself craving.
