## Description

Prism Echo puts you in charge of a tiny optical workshop where every prism is made to order.<br><br>Run the full production line across six hands-on stages. Grind the blank while the angle error drifts with machine noise, then lock it in before you overshoot. Tune polishing fluid concentration and disk speed into their sweet windows and watch the interference rings converge. Fire the autocollimator at the perfect moment for the angle self-check. Hold vacuum steady in the coating chamber and stop deposition right at the target film thickness on the live reflectivity curve. Align and cement prism pairs, then certify your work on the spectrometer.<br><br>Orders rotate between right-angle, roof and beam-splitter prisms, each with its own angle tolerance and base pay. Settlement is simple: angular accuracy times transmittance decides your coins.<br><br>Spend coins in the workshop shop on six permanent upgrades that all truly work: a CNC grinder that tames angle noise, a thermal polish lab that widens the sweet windows, a laser interferometer that reveals the exact ring count, an ion-assist coater that adds transmittance, an auto cement station that doubles the tolerance zone, and a partner contract that boosts every payout.<br><br>No ads, no timers, just craftsmanship. Can you earn three stars on a roof prism?
