  BK7 and UVFS Corner Cube Retroreflector Prism   are designed to deviate incident light by 180 degrees independently of an angle of incidence. These corner cube prism   have three mirror surfaces with angles at 90 ° to each other, juxtaposed to form the corner of a cube with the entrance face perpendicular to the cube's diagonal.   Corner Cube Retroreflector Prism Description   A corner cube retroreflector, also known as a CCR or trihedral optical prism, is an optical structure that consists of three adjacent, mutually-orthogonal plane-reflecting surfaces which form the corner of a cube. The corner cube reflects an incident ray at a specific angle, independent of the prism and beam orientations.   Ecoptik corner cube prisms are used in a wide variety of applications such as spectroscopy, battlefield technology and satellites. Corner cubes enable range finding for weapons systems and aid in performing other precise displacement and distance measurements. For example, a satellite in

  An anamorphic prism pair   is a pair of prisms which is usually used for reshaping the profile of a laser beam. For example, the elliptical beam from a laser diode can be transformed into a beam with circular cross-section, as is needed for many applications, by using an optical prism pair as a beam expander for only one direction (e.g., the horizontal one). Of course, one can also just modify the ellipticity, or convert a circular beam into an elliptical one.   Anamorphic Prism   Description   Diode lasers usually have elliptical beam profiles. In most cases, though, the shape of the circular beam is required, such as pattern matching with the external resonator to make the beam size adapt to the small aperture through the isolator. A deformed pair of anamorphic prisms   is used to transform an elliptical laser diode beam into an approximately circular beam to amplify an elliptical beam in one dimension.   For more information about custom optical components   and custom optical pri

  Neutral optical density filter   is often used in imaging or laser applications to avoid strong light damage to camera sensors or other optical components. This kind of optical density filters absorb or reflect untransmitted light to evenly reduce transmission in a given part of the spectrum.   Ecoptik (also known as BRD Optical) provides different types of neutral optical density filter wholesale. If you want to get the neutral density lens filters   price, please feel free to contact us.   Description Of Neutral Optical Density Filter     Ecoptik makes fixed OD value neutral density filter by depositing Inconel film on a clear cubstrate. The advantage of the optical density filter is in the broader band and lower ripple than that of absorptive density filter. The coated wavelengthcan be extended to 200nm to 1100nm or more. The disadvantage is that there is some reflective light on the optical filter glass. The OD value can vary from 0.1 to 0.5. The OD value is controlled by coating

  A dielectric mirror , also known as a Bragg mirror, is a type of mirror composed of multiple thin layers of dielectric material, typically deposited on a substrate of glass or some other optical material. By careful choice of the type and thickness of the dielectric layers, one can design an optical coating with specified reflectivity at different wavelengths of light. Dielectric mirrors   are also used to produce ultra-high reflectivity mirrors: values of 99.999% or better over a narrow range of wavelengths can be produced using special techniques. Alternatively, they can be made to reflect a broad spectrum of light, such as the entire visible range or the spectrum of the Ti-sapphire laser. Mirrors of this type are very common in optics experiments, due to improved techniques that allow inexpensive manufacture of high-quality mirrors. Examples of their applications include laser cavity end mirrors, hot and cold mirrors, thin-film beamsplitters, and the coatings on modern mirrorshade

  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 Pyramid Optical/ Tetrahedron Prism   A tetrahedral 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 light, and the other three

  A plano- convex cylindrical lens   is used to condense light in one axis.  A positive plano cylindrical lens is able to create a line image from a point of light, to change the aspect ratio of an image or to focus collimated input light to a line. Plano- convex cylindrical lenses are typically used for illumination of slit and line detector arrays, laser projection, laser line focussing and anamorphic beam shaping. If you have any demand, please contact Ecoptik (also known as BRD Optical).   Plano Convex Cylindrical Lens Descriptions The plano concave cylindrical lens   acts symmetrically on the incident light in both directions, while the convex cylindrical lens acts in only one direction on the incident light. A typical application is to shape a deformed beam with a pair of plano-convex cylindrical lenses. A pair of positive plano-convex cylindrical lenses can be used to collimate and round the output of the laser diode. Another possible application is to focus the diverging beam o

  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 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.   Custom Glass Reticles Applications The glass reticle is generally installed on the focal plane of the right eyepiece of the telescope or scope. It is made of a thin glass wi

  Ecoptik (also known as BRD Optical) provides meniscus lens in both positive and negative focal lengths. These meniscus lenses are useful when used with another lenses to increase or decrease the focal length. This meniscus lens element configuration does not introduce any additional coma or spherical aberrations   Description Of Positive&Negative Meniscus Lens Ecoptik (also known as BRD Optical) provides meniscus lens in both positive and negative focal lengths. On the aspect of shape, it can be divided into convex meniscus lens   and concave meniscus lens . On the aspect of the effect, it can be divided into diverging and converging meniscus lens .   Positive Meniscus Lens A positive meniscus lens consists of two curved surfaces with similar radii of curvature and has a positive focal length. Positive meniscus lens are typically used for related applications such as reducing the focal length of another lens, increasing the numerical aperture, etc.In order to reduce spherical abe
