unique technological expertise for exact measurement and precise results
Optical path length tolerances: Optical path length tolerance is a particularly important parameter for photometric applications because it influences the accuracy of the measurements and precision of the results. These tight tolerances make Hellma Analytics products ideally suited for collecting reliable and reproducible results.
- Quartz 0.01 mm to 0.05 mm ± 0.003 mm
- Quartz 0.1 mm to 0.2 mm ± 0.005 mm
- Quartz 0.5 mm to 20 mm ± 0.01 mm
- Quartz 30 mm to 100 mm ± 0.02 mm
- Special Optical Glass 0.1 mm to 10 mm ± 0.01 mm
- Special Optical Glass 20 mm to 100 mm ± 0.03 mm
- Optical Glass 10 mm to 20 mm ± 0.05 mm
- Optical Glass 20 mm to 100 mm ± 0.1 mm
These optical path length tolerances apply to absorption cells. For fluorescence cells, both for the direction of excitation and emission the tolerance is ± 0.05 mm.

transmission of empty cells made of different materials
When comparing the transmission values of various cuvettes, it is essential to ensure that the same measurement conditions are in place. Please note that the transmission curves shown were plotted using measurements taken from empty cuvettes (2 windows).
