Frequency Change by Thermal Shock

The smaller frequency changes against thermal shock, the higher rate stability is. Besides, the smaller difference between each data is, the better the reproducibility is.

Halogen lamp irradiation starts at 10 sec-point, stops at 40 sec-point.
(ave: Mean value of frequency change, σ: Standard deviation)

Variation Distribution of Oscillation Frequency

The more crystals which have small frequency variation are, the more stable measurement is.

Measurement without deposition.
(ΔF: Frequency variation)
