Silica gel packets are small, moisture-absorbing sachets containing silica gel beads. They play a vital role in preventing moisture damage, mold growth, and corrosion in various products and packaging, ultimately helping to maintain their quality and integrity.
Shipping container desiccants are available in a variety of forms, including desiccant bags, canisters, and hanging bags. They are generally made from adsorbent desiccant materials such as silica gel, calcium chloride, and activated alumina, and are used differently according to their application. Each type of desiccant has its own advantages, applications, and uses, so it is important to choose the right one for your shipping container needs.
Features of JH-907 ITE Mini Hearing Aid Hearing Amplifier
1. The lightweight and easy operation, you won't feel anything after you wear, very comfortable;
2. Corresponding uncomfortable threshold properly adjust the maximum output, protect ear， low distortion;
3. 3 different earplugs are provided, which can fit different people's ear;
4. Mini ITC hearing aid type with small, it is even not as big as a fingertip, so that can it will be invisible after wear.
5. Beautiful design with a useful pulling line to take out the hearing aid from the ear, some hearing aid may too small to take off after using, with this pulling line, the user can be easy to take it;
6. The experienced manufacturer producing and factory directly sell, reasonable price, high quality.
Precautions of JH-907 ITE Mini Hearing Aid Hearing Amplifier
1. Adjust volume to the minimum level or switch off before wearing.
2. To choose the right size of ear tips to avoid any extra noise.
3. Increase volume gradually to avoid the sudden increase in sound.
4. If you hear a howling, check the ear (silica gel) is appropriate and whether the size of the plug is tight, the appropriate choice of earplugs and plugged, make sure no air leakage.
5. Please regularly clean the earplugs in order to ensure the normal use of hearing aids.
6. Use for long periods of time, please remove the batteries to prevent rot erosion hearing aid components.
7. Keep out of reach of children.
8. The device is not water resistant.
Micro Prisms, Rhomboid Prisms, Penta Prisms, PBS, Custom Coating
Hyperion Optics supplies a range of prisms to meet UV-Visible-NIR applications, with high surface quality and tight tolerance angles. Our materials selection ranges from flint/crown glasses, fused silica, ZnSe, CaF2 etc.
Introduction of Optical Prism
An optical prism is a transparent object which is formed by two intersecting but uneven dimensions. It is used to separate light or cause the beam to be dispersive, and the material is usually glass, crystal, etc. It is widely used in optical instruments.
Classification of Optical Prism
According to the uses of optical prisms , it can be divided into:
1. Deviation optical prism: let light change direction through a prism, and generally a prism less inclined is called a wedge or thin prism, the achromatic Fresnel biprism can also be used for deflection(no dispersion).
2.Dispersive prism: the refractive prism of a large Angle, mainly used in spectral instruments, the main function is in refraction.
3.Reflecting prism occupies a significant position in the non-dispersive prism, it can change the direction of the light as well as the image shift. It is usually used to reduce the light consumption with full reflection.
4. Polarizing prism: to separate polarized light from non-polarized light, it is used to study some physical phenomena of polarization or to control the strong light.
5.In the microscope, a prism is also used to complement the light.
Uses of Optical Prism
Optical prisms play many different roles in optics, and the combination of prism can be used as a beam splitter, a deflector, etc. But in most applications, only the dispersive function of the prism is used, or to change the direction of the image and the direction of beam propagation. The function of dispersion makes the prism an excellent dispersive element, the role of the prism plays in the spectrometer, spectrograph and monochromator. In many optical instruments, the prism is oft
