Definitions
- a fourth aspect of the present invention is an objective lens for a microscope including an optical system including the above-mentioned junction lens.
- the third aspect of the present invention is an optical system including the above-mentioned optical element.
- the present embodiment an embodiment of the present invention (hereinafter, referred to as “the present embodiment”) will be described.
- the following embodiments are examples for explaining the present invention, and are not intended to limit the present invention to the following contents.
- devitrification-resistant stability means the resistance of glass to devitrification.
- devitrification means that the transparency of the glass is lost due to crystallization or phase separation that occurs when the temperature of the glass is raised above the glass transition temperature or when the temperature is lowered from the molten state to the liquid phase temperature or lower. It means a phenomenon.
- Li 2 O is a component that lowers ⁇ P g and F and improves the meltability of glass. If this content is too high, the devitrification resistance stability will decrease and the Abbe number will increase. From this point of view, the Li 2 O content is 2% or more and 8% or less. The lower limit of this content is preferably 3%, more preferably 4%. The upper limit of this content is preferably 7%, more preferably 6%.
- the image pickup device CAM is provided with an auxiliary light light emitting unit EF that emits auxiliary light when the subject is dark, a function button B2 used for setting various conditions of the image pickup device CAM, and the like.
- the multiphoton microscope 2 includes an objective lens 206, a condenser lens 208, and an imaging lens 210. At least one of the objective lens 206, the condenser lens 208, and the imaging lens 210 is provided with an optical element using the optical glass according to the present embodiment as a base material.
- the optical system of the multiphoton microscope 2 will be mainly described.
- the optical glass according to each Example and each Comparative Example was produced by the following procedure. First, glass raw materials such as oxides, hydroxides, carbonates, and nitrates were weighed so as to have a total weight of 100 g so as to have the chemical composition (mass%) shown in Tables 1 to 7. Next, the weighed raw materials were mixed and put into a platinum crucible, melted at a temperature of 1300 to 1400 ° C. for about 1 hour, and homogenized by stirring. Then, after lowering to an appropriate temperature, it was cast into a mold or the like and slowly cooled to obtain each sample.
- glass raw materials such as oxides, hydroxides, carbonates, and nitrates were weighed so as to have a total weight of 100 g so as to have the chemical composition (mass%) shown in Tables 1 to 7.
- the weighed raw materials were mixed and put into a platinum crucible, melted at a temperature of 1300 to 1400 ° C. for about 1 hour, and homogenized by stirring
- T l Liquid phase temperature
- the liquidus temperature (T l ) of each sample is set to a high temperature by holding the glass in a devitrification test furnace with a temperature gradient of 1050 to 1250 ° C. for 18 minutes, and then observing the presence or absence of crystals with a microscope at a magnification of 100 times.
- the minimum temperature was set so that devitrification does not occur when viewed from the side.
