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)

Matching error: Within 1.5% (240 nm)
Transmitting surface: 2
Optical path length: 10±0.01mm
Average sample volume: 3.5mL
EXTH: 48mm
EXTW: 12.5mm
INTW: 10mm
