Bk7 Optical Glass Beam Splitting Prisms Coated Options Penta Prism

Product Description

Product Description

A prism is a transparent object formed by two intersecting planes that are not parallel to each other, used for splitting light or causing dispersion of light beams. A prism is a multi-faced solid made of transparent materials (such as glass, crystal, etc.). It is widely used in optical instruments. Prisms can be classified into several types based on their properties and uses. For example, in spectroscopic instruments, the "dispersive prism" that decomposes composite light into spectra is commonly used; the more commonly used one is the equilateral prism; in periscopes, binocular telescopes, and other instruments, it is used to change the direction of light and adjust the imaging position, which is called a "total reflection prism", and generally a right-angle prism is adopted.

 

Fushi Optics can provide customers with a variety of replicated grating products such as diffraction gratings, transmission gratings and holographic gratings to meet different needs.

Optical Applications‌

Prism, a polyhedron made of transparent material is an important optical component. The plane where light enters and exits is called the side plane, and the plane perpendicular to the side plane is called the principal section plane. According to the shape of the principal section plane, it can be divided into prisms, right-angle prisms, pentagonal prisms, etc. The principal section plane of a prism is a triangle, and there are two refractive surfaces. The angle between them is called the apex angle, and the plane opposite to the apex angle is the base plane. According to the refraction law, light passing through a prism will be deflected twice towards the base plane, and the angle between the outgoing light and the incoming light is called the deflection angle. Its size is determined by the refractive index n of the prism medium and the incident angle i. When i is fixed, different wavelengths of light have different deflection angles. Among visible light, the deflection angle is the largest for violet light and the smallest for red light. In modern life, prisms are widely used in digital devices, science and technology, medical instruments, etc. Common digital devices: cameras, closed-circuit television, projectors, digital cameras, digital video recorders, CCD lenses, and various optical devices; science and technology: telescopes, microscopes, level meters, fingerprint scanners, gun sights, solar converters, and various measuring instruments; medical instruments: cystoscopes, gastroscopes, and various laser treatment equipment.
