(A) refraction and refractive index

In a homogeneous isotropic medium, light is propagated in a straight line between two points, and when a transparent object is passed through different densities, a refraction occurs, due to the difference in the propagation speed of light in different media. When the light that is not perpendicular to the transparent object enters the transparent object (such as glass) from the air, the light changes direction in its interface and forms a refraction angle with the normal.

(B) the performance of the lens

The lens is the most basic optical element that makes up the Digital Microscope optical system, and the components such as eyepiece eyepiece and condenser lens are composed of single and multiple lenses. According to its different shape, can be divided into convex lens and concave lens two categories.

When a beam of light parallel to the optical axis passes through the convex lens and then intersects at a point, the point is called "focal point", through the intersection and the plane of the vertical optical axis, called "focal plane". The focus of the two, in the object of the focus of space, called "the focus of the object," where the focal plane, called "object side of the focal plane"; the other hand, in the square of the focus of space, called " Where the focal plane, called "cube square plane."

Light through the concave lens, into a positive image, and convex lens is a positive image. Real image can be displayed on the screen, and virtual image can not.

First, the Digital Microscope daily use of the Notes

1. The halogen lamp voltage should be adjusted to a minimum during the Digital Microscope switch.

2. When converting the objective lens, rotate the objective frame and do not turn the objective lens directly.

3. Fluorescent light source mercury lamp due to short service life, in order to ensure as much as possible to extend the use of time and safety, mercury lamp power on / off interval

Time must be greater than thirty minutes.

4. Digital Microscope of the optical components should be adjusted in place so as not to affect the Digital Microscope

The normal work. If not in place, then the observation will usually see the crescent-shaped shadow.

5. Use the oil mirror should be used with professional oil, do not use other media , so as not to damage the lens. Every time

After wiping the oil mirror, wipe the oil mirror. 

6. Do not touch the surface of the optical parts directly, so as not to leave your fingers printed on

Face, affect the observation effect.

7. In the demolition of automatic Digital Microscope condenser, fluorescent filter box and other components, should be in the case of power

To operate.

8. Because of the effective working distance / characteristic of each section of Digital Microscope, you should fully understand the characteristics and

Measuring range, so as to avoid improper operation, the Digital Microscope and its accessories damage.

Tip: 1. When observing the sample , do not hit the object with the sample, so as not to crush the lens lens.

2. Move the Digital Microscope, it should be done carefully, so as to avoid the vibration of the optical components and optical damage, affecting the Digital Microscope usage of. 

 The daily maintenance and routine maintenance of the two Digital Microscopes

1. Digital Microscope daily general maintenance

1) After the Digital Microscope is finished, turn off the power and cover the dust cover.

2) Do not place the Digital Microscope in a damp room and keep it well ventilated. The temperature of the Digital Microscope chamber should be kept at +10-

+35 degrees between the humidity at +35 degrees when not more than 75%. It is recommended to configure the dehumidifier.

3) Digital Microscope of the optical components, such as long-term do not have to be properly kept, it is recommended to place in the dry dish.

4) Do not touch the surface of the optical parts by hand, so as not to leave your finger on it.

2. Clean the Digital Microscope

1) Remove the dust on the surface of the optical parts, should use a soft brush, wash ear, mirror paper or long fiber skim cotton swab.

2) remove the soluble and water dirt, with an appropriate amount of harmful substances without detergent to wipe the water.

3) Digital Microscope of the optical components, such as long-term do not have to be properly kept, it is recommended to place in the dry dish.

4) Do not touch the surface of the optical parts by hand, so as not to leave your finger on it.

2. Clean the Digital Microscope

1) Remove the dust on the surface of the optical parts, should use a soft brush, wash ear, mirror paper or long fiber skim cotton swab.

2) remove the soluble and water dirt, with an appropriate amount of harmful substances without detergent to wipe the water. 3) Remove the oil or grease , with long fiber dipped cotton swab dipped in a specially prepared optical cleaning solvent to wipe.

Note:

1. Wipe the surface of the optical components, you should first use the ear to remove the surface of the larger parts of the dust particles, so as not to wipe

Scratch the surface of the optical part. And then use the cotton swab from the center of the optical components of the center, from the inside out to create a concentric circle to wipe,

Force to be uniform, not too hard. Do not wipe the surface of the optical parts with the same cotton swab. The wiping method is shown below:

Optical cleaning solvent configuration .

2. Fluorescent modules, etc. Special treatment of the optical components, do not use any solvent to wipe, so as not to damage.

3. Prohibit the use of benzene solvents.

4. When wiping the mold, you should contact the maintenance department before, so as to avoid the use of solvents on the optical components damage.
