    Custom dimensions, materials, and coatings available

    Dispersing Prisms

    Used to separate a beam of light into its component wavelengths, or to add dispersion to a system.  Often used at the minimum deviation angle so that incident and exit angles are equal, prism magnification is one, and reflection losses are low.

    High-quality surface polish for use in high power applications

    N-BK7, UV-grade fused silica, N-F2, and Suprasil 1 catalog options

    非球面透镜:

     

    Plano-Convex Cylindrical Lenses

    Used to condense light in one dimension only.  Positive cylindrical lenses can focus input collimated light to a line, transform a point of light to a line image or change the aspect ratio of an image. Useful for laser line focusing, laser projection, anamorphic beam shaping, and illumination of slit and line detector arrays. 

    Plano-Concave Cylindrical Lenses

    Used to expand light in one dimension only. Negative cylindrical lenses diverge input collimated light away from a line. Useful for laser line generation, anamorphic beam shaping, and one-dimensional compression of images.

    多元素透镜:

     

    Achromats

    Used to focus two or more wavelengths at the same point in the image plane.  Reduced spherical aberration and coma.  Well-suited to broadband applications like astronomical telescopes, plasma spectroscopy, biomedical instrumentation, and laser beam steering.  Also ideal for use at single wavelengths, as performance is far superior to simple singlet lenses.

    Aplanats

    Used with monochromatic light to generate the minimum focal spot size by eliminating coma and spherical aberrations.  Diffraction-limited performance.  Ideal for nonlinear optics, laser beam expansion and collimation, interferometers, materials processing, and fiber optic coupling.      

    Objective Lenses

    Achromatic or aplanatic lens systems designed to operate at lower f/numbers.  Used for collimation and focusing of laser beams, visual inspection, and microscopy.

    Beam Expanders

    Adjustable beam expanders used to increase or decrease beam diameter.  Compact Galilean design.  Used for illumination, laser communications and alignment, and light focusing.

    Shear-Plate Collimation Testers

    Ideally suited to assess and adjust the collimation of laser light. Composed of a high quality λ/20 optical flat mounted with a viewing screen, these shear plates allow rapid visual wavefront analysis via interferometry. They can be used to measure the wavefront radius of curvature and power of long focal length optics, and for evaluation of wavefront symmetry or aberrations.

    OD 3 extended blocking

    Lower power

    Neutral Density Filters

    Used to attenuate, split, or combine beams in a wide range of irradiance ratios, with no significant dependence on wavelength.

    Best suited to narrow bandwidth and operating temperature range

    Compound zero-order waveplates

    used to rotate polarization (λ/2 retardation) or convert between linear and circular polarization (λ/4 retardation).  Recommended for use with diode, tunable and femtosecond lasers.

    脉冲线超快光学:

     

    PulseLine Mirrors

    Broadband, high reflectivity, high laser damage threshold mirrors designed with low and controlled group delay dispersion characteristics specifically for ultrashort laser applications.

    PulseLine Polarizers

    Polarizers divide a beam of light into two highly polarized beams, making them ideal for isolation or routing of a specific polarization.  Extinction ratio and power handling are important factors to consider when choosing a polarizer, particularly for laser applications.  With plate and cube formats to choose from, as well as options for 45° AOI or Brewster angle operation, we have the right polarizer for your needs.

    PulseLine Prisms

    Prisms are used to steer light, with cut and material determining how they do so.  CVI Laser Optics offers a variety of prism types for bending light, reorienting images, separating wavelengths, and magnifying beams.
