| 6 ELEMENTS / 4 GROUPS |
| f ≈ 39.0 mm |
| F/2.8 |
| 2ω ≈ 58.0° |
| 1 ASPHERICAL SURFACE (GMo PRODUCTION CORRELATION) |
CONSTRAINED_RECONSTRUCTION: source whole-system focus mechanism, but no finite-focus spacing table. The existing 0.30 m endpoint and intermediate BF interpolation are approximate product-correlated unit-focus states; production internal motion is not established by this source.
