# Zemax-compatible lens data for: meniscus_positive_BK7
# Description: Positive meniscus R1=30, R2=60 mm (f ~ 110 mm)
#
# Test conditions
#   Primary wavelength: 1.3100 um
#   Source: collimated on-axis plane wave
#   Aperture: clear semi-diameter = 5.0000 mm (diameter 10.0000 mm)
#   Stop surface index: 1
#   Paraxial EFL (at this wavelength): 115.285 mm
#   Residual (piston+tilt+defocus) RMS (slant): 53.12 nm
#   Expected OPD in Zemax: compare to the piston+tilt+defocus-removed trace; the two should agree to the Zemax sampling limit for aberration shape (spherical, coma, higher).
