Spherical Lens is available in spherical shape to focus beam as well as expansion. As the lens doesn't focus parallel rays to a common point, its "focus" depends on the distance from the centre of the lens. This phenomenon of "focus shift" helps focusing the image with the diaphragm that is wide open. It is widely used in different applications; hence it should be selected carefully. It should be chosen on the basis of f/number, conjugate ratio, lens material, transmission, etc. In addition, wave front distortion, types of coating and scattered light also keep in mind.
This precision lenses is developed from high-quality optical materials for high transmittance. It is designed with careful considerations to ensure to provide the fine shape to the lenses and shapes. It is available with high surface exactness and surface quality. It is used as shaving mirrors, reflectors in the headlights of vehicles, street light bulbs, search lights, etc.
Features of Spherical Lens:
A cylindrical lens is designed to focus light into a line with its curved face. The faces of the lens are its different sections that focus the image into a line parallel to the intersection and a plane tangent to it. The lens carefully compresses the image in the direction perpendicular to this line. It leaves it unaltered in the direction parallel to the tangent plane. This cylindrical lens is kept in front of the illumination object to produce the light sheet that is further used in imaging.
This cylindrical lens is designed for a range of applications that need one-dimensional shaping and direction of the light source. It is available in plano-concave or plano-convex configurations that are designed for expanding or focusing light. This offered cylindrical lens is available in uncoated or anti reflection coated materials to ensure to provide the best performance.
Features Of Cylindrical Lens:
An Aspherical Lens has surface profiles. The prime benefit of the lens is to correct the spherical aberration and create an optical effect that makes the incident light rays focusing at different points while developing an image. This focuses light to a small point for ensuring no blur and improving the quality of the image.
It is used to replace complex multi-lens system to get smaller as well as lighter product. It is also employed to reduce aberrations in multi-element wide-angle as well as fast normal lenses. In addition, it can be used in combination with reflective elements and for collimating diode lasers. Its eyeglass lenses allow crisper vision while looking in different directions than the lens optical center. Its ability to reduce the magnification effect helps individuals to have different powers in the 2 eyes (anisometropia).
Features of Aspherical Lens:
1) Perfectly designed lens that minimizes aberration by correcting the conic constant as well as aspheric coefficients.
2) Allows optical designers to make the aberrations correct using elements.
3) Ensures to provide better optical results and reduces the overall cost of production.
4) Ideal to produce a wider field of view with improved peripheral vision.
Ball lens is a great optical component developed to enhance the signal coupling among detectors, fibers and emitters. This lens is designed using a single substrate of glass to focus or collimate light according to the input sourceâs geometry. It is widely used in ball pre-forms for aspheric lenses, imaging optics systems, endoscopy, projection optics systems, bar code scanning, astronomical optics, sensors and other applications. It is available with higher spericity of more than 0.6m with uniformly and precisely ground design. In addition, it is available with outstanding surface roughness to ensure to provide accurate and required results.
This is designed from BK7 Grade A Optical Glass having dimension tolerance is ± 0.002mm. The sphericity of the lens is up to 0.6Î¼m. In addition, this lens is available in different coatings available in varied specifications provided by the users.
Features of Ball Lens:
Mirror has a flat or planar reflective surface. It creates images of objects kept in front of it. It works on the principle of creating images in behind the plane. It produces virtual and upright images of the same shape as well as size as the object. Its optical power is zero and focal length is infinity. It is designed to be used in a variety of applications from beam steering, lab or OEM integration, folding to interferometry. In addition to this, it is also used within imaging systems as optical component. As surface flatness is a dimension of the surfaceâs roughness, high surface flatness reduces the light lost quality through dispersion.
It is provided in standard metallic mirror coatings using different materials from Gold, Silver, Aluminum, or Dielectric. It is also available with Fused Silica or other substrates to make it ideal to be used at the places where temperature fluctuation is the point.
Features of Mirror:
Beamsplitter is an optical component widely used to split the incident light into two separate beams at a designated ratio. This is developed from high grade glass materials having laser grade surface flatness. It comes with high surface quality for tighter tolerance. It is widely used to join two different beams into a single one. It is designed to offer general purpose laser beamsplitting as well as merging visible through near infrared usages.
It is available in two types as per their construction such as cube or plate. Cube beamsplitter is available in polarizing as well as non-polarizing models. On the other hand, the plate beamsplitter is available with a coated front surface to determine the beam splitting ratio as the back surface is wedged as well as AR coated for minimizing the ghosting along with interference effects.
Features of Beamsplitter:
Optical Filter is a device that transmits light selectively of different wavelengths. It is used as a plane glass or plastic devices in any optical path. The optical properties and features of the filter are shown by its frequency response that fuehrer demonstrates the degree and phase of each frequency component.
This selectively transmits light in a fixed range of wavelengths. It can easily pass long wavelengths, short wavelengths or band of wavelengths that blocks shorter as well as longer wavelengths. The created passband is wider or narrower and the transition between maximal and minimal transmission is sharp or gradual. This is widely used for photography in many optical instruments, scientific and technical work. It is also used in astronomical domain for restricting light passed to the spectral band of interest. In addition, it has also become a vital part in fluorescence applications like fluorescence microscopy and spectroscopy.
