用应变片法测定了五种光学玻璃在室温至60 ℃范围内的线膨胀系数。两种冕玻璃的膨胀系数为7.6 × 106/℃。发现一种稀土玻璃的膨胀系数稍低，但两种闪光玻璃的膨胀系数比其他玻璃大10%。
Coeffi cients of linear thermal expansion of five opt ical glasses were determined by a strain gage method for t he range between room temperature and 60° C. The coeffi cients of expansion of two crown glasses are 7.6 X 106 per deg C. A rare-earth glass was found to have a slight ly lower coefficient of expansion, but the coeffi cients of expansion of two fl int glasses are 10 percent larger t han t he other glasses.
