These filters are designed to give the desired attenuation (optical density) at the laser wavelength and to give the maximum luminous transmittance. Although the optical density is usually measured with a relatively low intensity source such as the Cary 14 Spectrophotometer, it must be verified under simulated use since it is known that certain materials bleach under laser irradiation. Measurements of various filters and goggles have been made with a Q‐switched ruby laser. Accuracy and reproducibility comparisons are made between laser measurements and those obtained from the Cary 14. Safety considerations were discussed. Comparisons have been made between the absorption spectra of the filters and the CIE photopic observer. Problems associated with the use of these filters were discussed.","PeriodicalId":78011,"journal":{"name":"American journal of optometry and archives of American Academy of Optometry","volume":"50 6","pages":"477-83"},"PeriodicalIF":0.0,"publicationDate":"1973-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1097/00006324-197306000-00006","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"15616804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
