    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

Elliptical Mirror, Ellipse Mirror - 1 views

  •  
    Elliptical Mirror is still a flat mirror, but the shape is cut into an oval, and the outer circle and the mirror into a 45 ° angle. When the elliptical mirror is mounted in the optical path by 45 [deg.], The optical aperture of the lens is just circular. Elliptical mirrors are also divided into metal coated mirrors and dielectric coated mirrors. The wide-band dielectric film reflector has a high reflectivity, and the metal film reflector has a wide reflection band. Elliptical mirrors are typically used at 45° where a circular cross section of a given size is asked for. Our stock range of elliptical mirrors are machined from standard sheets of enhanced aluminium giving 94% reflectivity for visible applications. Generally elliptical mirrors are used as secondary mirrors in Newton telescopes or mounting in a tube where maximum aperture is required such as in perescopes. Our stock mirrors have a guarenteed flatness of 1λ over 25mm. Where greater precision is required we offer elliptical mirrors with flatness better than λ/10 as a custom option. We also stock a range of standard front surface mirrors sheets for use in UV/ NIR and IR applications these can be cut and edged into elliptical mirrors at short notice. For more information on our stock elliptical mirrors, to place an order or to find out more about our custom capabilities please contact our technical sales team. Material: Soda lime float glass Diameter (minor-axis): +0 / -0.25 mm Thickness: ±0.15 Surface quality: 94%@450-650nm, AOI=0°-45° Hyperion Optics is a professional premium supplier. We provide Anamorphic Lenses, Collimating Lenses, optical assembly manufacturing, elliptical flat mirror, ellipse mirror and so on. Want to know more? Please contact us.

Penta Prism, Glass Prism - 1 views

  •  
    Penta Prisms are used to define right angles in optical systems. Penta Prisms, which provide right handed images, feature a ray deviation of 90°. Penta Prisms are five-sided prisms and unaffected by slight movements. Edmund Optics offers a variety of Penta Prisms for optimal performance in the Ultraviolet (UV), Visible, or Infrared (IR) spectrums. The Penta Prism will neither invert nor reverse the image. Penta prisms are extremely useful in alignment systems as they define a right angle very precisely and independently of angle of incidence. Rays entering one face emerge from the adjacent face at precisely 90 deg after they have undergone two reflections inside the prism for a total of 270 deg. The penta prism acts as a turning mirror which is insensitive to alignment. Penta prism is often used in Plumb Level, Surveying, Alignment, Range finding and Optical Tooling Factory Standard - Contact us for manufacturing limit or custom specifications Material: BK7 Grade A optical glass, Corning Fused Silica 7980, JGS1, JGS2 Dimension Tolerance: +/-0.1mm 90 Deviation Tolerance: Precision series: up to 2 arc seconds Flatness: Precision series: 1/4 at 632.8 nm Reflectivity: R > 95% per face from 630 to 680 nm Surface Quality: 60-40 scratch and dig Coating: On request Protective Bevel available Hyperion Optics is a professional premium supplier.
