Fluorescence observing apparatus and fluorescence measuring apparatus |
摘要 |
A fluorescence observing apparatus has an illumination system for irradiating a specimen with exciting light and an observation system for observing fluorescent light emanating from the specimen. Low-fluorescence glass is used for lenses of the first and seventh lens units of an objective lens used in both the illumination system and the observation system. The low-fluorescence glass has a platinum content of less than 1 ppm. Whereby, high-precision and high-quality fluorescence observations and fluorescence measurements become possible.
