The optically polished cell windows are heat-fired only, so there is no distortion.
All cells are checked for transmittance, and only those that pass are given the same match code. Material: Spectrosil® Quartz glass (Q)

Transmitting surface: 5
Optical path length: 10±0.01mm
Average sample volume: 0.7mL
EXTH: 45mm
EXTW: 12.5mm
