Roof Prism

图片
  W hat I s R oof P rism ? The roof or Amici prism deviates or deflects the image through an angle of 90 degrees. It is a right-angle prism whose hypotenuse has been replaced by a 90-degree TIR roof. Glass that does not contribute to the clear aperture has been trimmed away to reduce size and weight. Description Of Roof Prism Ecoptik Roof Prism is made from N-BK7, an RoHS compliant version of BK7, and can be used when a right angle deflection of an image or laser beam is required. In passing through the prism, the image is both deflected right-to-left and top-to-bottom. The hypotenuse of the custom optical prism  utilizes total internal reflection (TIR) to reflect the image through the prism. Polarization states may become rotated during reflection.   The roof or Amici prism deviates or deflects the image through an angle of 90 degrees.

Rod Lens

  Rod Lens Rod Lenses  are polished on the circumference and ground on both ends. Optical performance is similar to a cylinder lens. Collimated light passing through the diameter of the rod lens will be focused into a line. Optical glass and UV Fused Silica substrates are available for a variety of UV, Visible, and NIR applications. Description Of Rod Lens The optical rod lens is primarily used to change the design requirements for imaging size. For example, converting a spot into a line spot, or changing the height of the image without changing the image width. Rod lenses can be applied to linear detector illumination, barcode scanning, holographic illumination, optical information processing, computer, laser emission. Also, a cylindrical lens is used in high-power laser systems and synchrotron beamlines. At the same time, the requirements for rod lens parts are becoming higher and higher, especially in the high-power laser cavity and long-distance line interferometers. Such as high-p

Right Angle Prism

  Right Angle Prism Right-angle prism mirrors are extremely versatile optical components, commonly used as individual prisms and components of optical assemblies. A beam of light entering the leg of a right-angle prism mirror will deviate by a nominal value of 90°, while precise rotation of the prism controls beam alignment. When light enters the hypotenuse of the prism, it is commonly called a Porro prism. In this configuration, a light beam will undergo 180° deviation that is invariant in the azimuthal axis, while precise adjustment of the prism controls beam elevation.   Description Of Right Angle Prism Mirror A  right angle prism mirror is usually used to turn a light path or deflect an image produced by an optical system by 90°.Depending on the orientation of the prism, the image can be aligned left and right, upside down and left and right.Rectangular prism can also be used for image combination, beam deviation and other applications. When a right angle optical mirror  is used, s

Rhomboid Prism

  Rhomboid Prism Rhombic custom prisms  are used to displace a beam laterally without changing its direction. They may be coated to transmit part of the beam and produce two parallel and displaced emerging beams. Can be coated to produce a polarizing beam separator. These rhombic prisms are manufactured from either BK7A or Fused Silica. They are supplied uncoated but many coating options are available. Rhomboid Prism Description Ecoptik  rhomboid prisms are commonly used to displace a laser beam without changing its direction. In imaging applications, rhomboid prism will displace the optical axis without inverting the image. The lateral displacement is equal to the length of the prism. Rhombus prisms are widely used in the fields of optics, imaging, and photonics. They can be used to replace optical centerline beam folding and three-dimensional systems of different sizes. In modern life, optical rhomboid prisms are widely used in digital equipment, science and technology, medical equip

Reticles

The precision custom reticle is generally installed on the focal plane of the right eyepiece of the telescope. It is a thin glass with reticle dense lines engraved on the  surface of the pole book. In theory, this thin optical reticle glass  also participates in imaging and extends the focal length of the objective lens, which will have more or less influence on the length of the right eyepiece. Ecoptik (also known as BRD Optical) is one of the few companies producing custom glass reticles because the precision custom reticles require extremely high cleanliness. Any tiny dust will produce large black spots during observation. At the same time, the accuracy of the installation position of the custom reticle is extremely high. Therefore, try not to disassemble it. If it is disassembled, it must be as it is recovery. Types of Reticles Dashed Crosshairs Custom Glass Reticles Applications The etched glass reticle is generally installed on the focal plane of the right eyepiece of the telesco

Pyramid Optical/Tetrahedral Prism

图片
  Pyramid Optical /Tetrahedral Prism A pyramidal prism/angular cube reflector is always used to reflect a beam of light into the prism, regardless of the direction of the beam. Corner prisms are widely used where accurate alignment is difficult. Corner optical prism rear reflector/pyramid prism is designed to reflect any light or beam entering the prism surface, regardless of the direction of the prism, can be reflected back to itself. The mirror can only be used at a normal Angle of incidence. Therefore, corner prism retroreflector is an ideal choice for accurate alignment. They have three total internal reflections that work even at very large incident angles. N - BK7 Corner Cube Retroreflectors is made by the precision of N - BK7, suitable for all kinds of visible light. Description Of Optical Pyramid/Tetrahedral Prism A tetrahedron prism, also known as a pyramidal prism, consists of four planes with different spatial directions. One of the four planes is the incidence/exit plane of

Quarter-wave plate

  The 1/4 wave plate uses the anisotropic characteristics of the material to have different refractive indexes and propagation speeds for light in different polarization directions, resulting in a phase difference between the two components, and converting linearly polarized light into circularly polarized light, or converting circularly polarized light into linearly polarized light.   The 1/4 wave plate can realize the mutual conversion between linearly polarized light and circularly polarized light. Clever use of wave plates can also generate optical isolators, or simultaneously change the propagation direction and polarization direction of light.   The 1/4 wave plate can be applied to the laser. In the laser cavity, two quarter-wave plates placed on both sides of the gain medium can achieve single-frequency operation. A half-wave plate is placed between the laser crystal and the resonator mirror to reduce the depolarization loss. The combination of a half-wave plate and a polarizer
