Optical metrology
Tools for beam propagation, lens selection, focal systems, and measurement verification.
星尘矩阵实验室 / Optical metrology tools
A small research software lab building local-first tools for optical measurement, calibration, and repeatable engineering analysis.
The lab focuses on compact web tools that turn optical formulas, calibration procedures, and engineering datasets into reproducible browser workflows.
Tools for beam propagation, lens selection, focal systems, and measurement verification.
Single-purpose calculators and analyzers with explicit formulas, visible outputs, and exportable records.
Browser-native processing that keeps source files on the user machine whenever possible.
Released tools are small, auditable, and built around one measurement workflow at a time.
Import Excel beam readings, fit propagation curves, calculate M², waist position, and divergence angle.
Calculate effective focal length for separated thin lenses, or search stock lens combinations by target focal length.
Solve repetition rate, period, duty cycle, pulse width, and off time from any two known pulse timing parameters.
