- Metallurgical Microscopes
By: Kathy Brasch | - A metallurgical microscope is an optical microscope which differs from other microscopes in the method of specimen illumination. Since metals are opaque substances they must be illuminated by frontal/reflected lighting, therefore on metallurgical microscopes the light source is located within the microscope tube. This is achieved by a plain glass reflector installed in the tube. The image quality and its resolving power are mainly determined by the quality of the objective. The common magnifi ...

- Abbe Refractometers
By: Kathy Brasch | - Refractometers are measuring instruments which put the phenomenon of light refraction (bending) to practical use. They are based on the principle that as the density of a substance increases (such as when sugar is dissolved in water), its refractive index rises proportionately. Refractometers were devised by Dr. Ernst Abbe, a German/Austrian scientist in the early 20th century.
The prism in a refractometer has a greater refractive index than the sample solution. Measurements are read ...

- The Story Of The Microscope Stage
By: Andrew Long | - The microscope stage has simple beginnings. As first, for Anton Leeuwenhoek, it was merely a needle-like projection that held a drop of water before a glass sphere for magnification. The tip of the needle had an eye that the water was suspended in, and then was screwed up in front of the magnifier.
When the first tube microscopes were developed, the microscope stage became more or less as it is today: Flat, with a hole for the light source to come through. The first stages di ...

- Advances In Microscope Technology Means Clearer Results
By: Andrew Long | - Microscopes have come an unbelievably long way since they were first developed in the late 16th century. While Antonie van Leeuwenhoek is often credited with being the creator of the first microscope, it was actually one of two optics pioneers who is the real father of the instrument: Zacharias Jansen or Hans Lippershey. Of the three, it is Lippershey who is most widely considered to be its inventor, an idea which is especially credible given that he was also the designer of the first modern-sty ...

- A Brief History Of The Microscope
By: Andrew Long | - From the beginning, man has suspected that there were worlds hidden from his naked eye. If he could look very closely at a drop of pond water, he could barely perceive things moving of their own accord. This tantalizing discovery led to the need to "see" closer.
Since Ancient times there has been glass and the forming of glass objects. During the time of Pliny the Elder, around the First Century A.D., there were globes of glass or crystal that were shaped just right, enabling the ...

- How Modern Technology Has Changed Microscopy
By: Andrew Long | - The simplest form of magnification is ironically a drop of water. It makes a perfect lens. Have you ever noticed the type of a magazine or newspaper while a drop of water rests on it? The type face becomes bolder, or magnified, due to the refraction of light coming back through the clear drop of water.
Refraction is the key to how lenses work. A lens made of crystal or glass can be concave or convex. The concave lens tends to refract light so that an image is smaller when viewed t ...

- Microscope Illumination Lights The Way For Scientific Discovery
By: Andrew Long | - Even the most sophisticated of microscopes will not yield high quality images which are genuinely of value to researchers without adequate microscope illumination. The light sources used in microscopy have advanced considerably since the days of van Leeuwenhoek's sightings of "wee animalcules" in the beginning, the only microscope light source available was natural sunlight or after sunset, candlelight.
Naturally, this was not conducive to capturing truly detailed, in depth viewi ...

- The Different Options For Lighting Your Microscope
By: Andrew Long | - The earliest known microscopes were primitive yet functional. They usually consisted of a tube with the lenses mounted within, and adjustment knob to raise or lower the objective over the specimen for focusing, and a mirror under the simple stage to illuminate the specimen with sunlight or candle. This limited the user to working with either sunlight, which moved across the room, or candle or oil lamplight, which flickered, thus making the observation of the specimen increasingly frustrating. ...

- Principals Of Refractometers
By: Kathy Brasch | - Water is placed in a reservoir. When a pencil is dipped into the water, the tip appears bent. Now put concentrated sugar water into a cup and try the same thing. The tip of the pencil should appear even more bent. This is the phenomenon of light refraction. Refractometers are measuring instruments in which this phenomenon of light refraction is put to practical use. They are based on the principal that as the density of a substance (e.g. when sugar is dissolved in water), it's refractive index r ...
