A beam splitter is primarily made by Honing / Lapping / Polishing. Lapping and polishing rub the part against a tool with fine abrasive slurry to reach mirror finishes and sub-micron flatness. Below is the full route to make a beam splitter, the materials it suits, the tolerances to expect and the main design points. The route is free, from the finder.
Step by step
How a beam splitter is made
The usual route, raw material to finished part. The amber step is where the beam splitter gets its basic shape.
Rough machining
Machine the beam splitter close to size, leaving grinding stock.
Tooling None Tolerance ±0.125mm, to ±0.025mm Lead 1 to 10 days
Heat treatment
Harden the beam splitter first so the finished surface stays hard.
Tooling n/a Tolerance can distort Lead days
Honing / Lapping / Polishing
Hone, lap or polish the critical surfaces to the tightest tolerance and finish.
Tooling Low Tolerance ±0.001 to 0.01mm Lead days
Clean and inspect
Clean and measure surface finish, size and roundness.

What a beam splitter should cost
Honing/lapping/polishing for the finest finish and flatness; slow and costly, use only where function needs it.
PER-PART COST vs VOLUME
Per-part cost drops as volume spreads tooling and setup over more parts. The exact figures for a beam splitter at your volume, in your currency, are in the dossier.
