Nebula in Our Galaxy

The asteroid is a small point in the universe, but it has become a hot spot for the people of the earth this summer. First, Japan's ostrich 2 probe flew to the asteroid Dragon Palace on the 27th, and then the American Osiris-REx probe will fly to the asteroid Benu in August. Why do humans need to

With the UK going coal-free for a record-breaking 90 hours over the weekend, energy sources such as solar and onshore wind now play a key role in generating electricity. However, with the urgent need for new energy sources to replace the 60% of the electricity produced worldwide by fossil fuel combustion, it has become necessary to look further afield to alternative energy sources.

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
