Wavelength accuracy < 0.05.
Wavelength repeatability ≤ 5 pm.
Resolution ≤ 0.5 nm.
Spectral range of visual amplifier: from 200 nm to 850 nm.
Minimal delay duration < 3 ns.
Maximal photocathode repetition rate - ≥450 kHz without UV function - ≥ 4 kHz with UV function.

Application.  Determination of singlet and triplet energy levels.
