Uncoated Window Substrates Controlled wedge or ultra-low wedge options to minimize angular deviation of the transmitted beam and reduce alignment errors. High surface quality and low wavefront distortion; suitable for achromatic beam sampling and sample or vacuum chamber windows. Wedge ≤ 10 arc sec for circular substrates Wedge ≤ 5 arc min for square or rectangular substrates Low wedge option: 30 ± 5 arc min Large wedge options: 1° or 3° |
棱鏡：
Uncoated Wedge Prisms Used to control deviation of an incident beam and eliminate stray beams due to back reflection. Applications in interferometry, quality testing of optics, and output coupling for high gain and sensitive lasers. Two wedge prisms can be combined for continuously variable beam steering through a cone of angles. Low wedge option: 30 ± 5 arc min Large wedge options: 1° or 3° Thicknesses from – mm standard, others custom Diameters from – mm standard, others custom |
Uncoated Right-Angle Prisms Used for routing a collimated beam of light through 90° or 180° via total internal reflection, depending on orientation. Also used for image rotation, for retroreflection, and as an external reflector. Broadbａnd performance with choice of antireflection coatings.
High-quality surface polish for use in high power applications N-BK7 and UV-grade fused silica catalog options 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 Equilateral prism has more dispersion; isosceles prism has better p-polarization transmission Custom dimensions, materials, and coatings available |
偏振片：
Cube Polarizers Available for narrow and broad wavelength bands from UV through near-IR, but prism interface can limit power handling (if epoxy is used for bonding). Easy to mount, mechanically durable High laser damage threshold options Laser line and broadbａnd wavelengths from 248 – 2000 nm, others custom |
Plate Polarizers Best for high energy applications, provided that broadbａnd performance is not needed. Minimal impact on beam quality (lowest TWE, low wedge, high surface quality). Highest laser damage threshold Lowest transmitted wavefront error (> λ/8) Nd:YAG & Nd:YLF laser wavelengths standard, others custom |
分束鏡：
Plate Beamsplitters Best for high energy applications, provided that beam displacement, “ghost" beams, and polarization sensitivity can be tolerated. High laser damage threshold Beam offset is ~ thickness of the substrate AR-coated back surface to minimize ghost reflections Available for power or wavelength separation |
Cube Beamsplitters Bonded interface avoids beam displacement, but interface can limit power handling (if epoxy is used for bonding). Ghost reflections are reduced, but still present. No beam displacement Easy to mount, mechanically durable High laser damage threshold options Available for power or polarization separation |
Beamsplitter Assembly High energy continuously variable beamsplitters combine a half-waveplate and polarizing beamsplitter, to achieve variable attenuation of the transmitted light.

非球面透鏡：
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. |
多元素透鏡：
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. |

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. |
