    This work is oriented to comparison of methods for iodine absorption cells quality evaluation. Optical frequency references based on molecular iodine represent one of the most used references for stabilizion of laser standards working at visible spectral range. Unfortunately iodine is a media with very high sensitivity to contamination so the chemical purity of iodine cells must be preciselly controlled. Traditional methods for iodine absorption cells quality checking have several difficulties and disadvantages, these problems complicate their common using in labs. Due to this reason we propose an alternative method of spectral linewidths measurement, which overcomes these difficulties of traditionally used approaches and which serves as a tool for iodine cells quality evaluation. In this work we present the results of comparison of two laser induced fluorescence setups (with and without the compensation for the laser source spectral mode-hops) with proposed method of selected hyperfine transition linewidth measurements and we discuss advantages and limitations of these methods for practical using.
