    Fiber laser engraving is an advanced technical process that involves the removal of a layer of material by using a focused laser beam. The beam irradiates and vaporises the target layer down to the required depth. It is quite similar to fiber laser ablation and can be successfully used on a number of materials like ceramics, metals and silicon.

    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

Dove Prism, Buy Glass Prism - 1 views

  •  
    Dove prisms are used as reflective prism inverting the image. Dove prism is shaped from a truncated right-angle prism. Normally, dove prisms are used in the parallel optical path based on critical angle principle to meet total internal reflection with limited FOV. A beam of light entering one of the sloped faces of the prism undergoes total internal reflection from the inside of the longest (bottom) face and emerges from the opposite sloped face. Images passing through the prism are flipped, and because only one reflection takes place, the image is inverted but not laterally transposed. A beam of light entering the sloped faces undergoes total internal reflection from the bottom surface, and emerges from the opposite sloped face. Also interestingly whtn dove prisms optical are rotated along longitudinal axis, the image rotates at twice the rate of the prism which have applications in fields such as interferometry, astronomy, and pattern recognition. Dove prisms can be also used as right angle prisms with sloped faces HR coated. Hyperion Optics supplies standard and custom made dove prisms according to your requirement; please refer to following spec grid for further capability study.

Parabolic Mirrors Manufacturer, Off Axis Parabolic Mirror - 1 views

  •  
    Hyperion Optics is a parabolic mirror manufacturer and offer custom parabolic mirrors for use from the UV(200 to 400nm) to the IR (1to 40µm) wavebands. Parabolic mirrors are typically designed as a segment of a larger parabola, manufactured from a metal substrate such as aluminum and coated in either enhanced aluminum, silver or gold as a standard. These mirrors focus light similar to a concave mirror with the significant exception being that the off-axis parabolic design redirects the incident light through 90%. Custom mirrors may be manufactured in a range of substrates and alternative coatings as required by our customer's specifications including UV and IR coatings and materials and alternative reflection angles. Every component is individually tested by our highly skilled technicians in our state of art metrology lab to ensure all parts meet our high-quality standards. For more information on our custom parabolic mirror capabilities, or to enquire after a custom quotation, please contact our technical sales team. Parabolic reflectors can be parallel to the optical axis of parallel light completely converged to the focus; the spherical aberration is zero. Parabolic mirrors are typically made as off-axis parabolic reflectors whose reflective surfaces are equivalent to a portion of the parent parabolic mirror. These sections retain the ability of the parent paraboloid to focus on a collimated parallel beam or collimated wide-point light source. Such an off-axis design separates the focus point from the beam path. Click here for more information about mirror designs. Hyperion Optics is a professional premium supplier. We provide Anamorphic Lenses, Collimating Lenses, hyp design, off axis parabola, off axis parabolic mirror and so on. Want to know more? Please contact us.

    When engraving using fiber lasers, unwanted material is removed to the required depth and shape to create an engraving. The process has striking similarities to laser ablation, where a pulsed fiber laser beam is used to target unwanted matter on a surface. The laser is used to irradiate and vaporise the targeted matter, effectively cleaning the surface.
