Plano-Convex Lens

Plano-Convex Lens

市场价:0.00

价格:0.00

 Plano-Convex Lenses are Optical Lenses with a positive focal length. Plano-Convex Lenses are ideal for light collimation or for focusing applications utilizing monochromatic illumination, in a range of industries including industrial, pharmaceutical, robotics, or defense. Lenses have one convex surface. For maximum efficiency, the second, plano (flat) surface should face the desired focal plane. Plano-Convex lenses are commonly used in a wide range of applications or industries.
Plano-Concave Lens

Plano-Concave Lens

市场价:0.00

价格:0.00

 Plano-Concave lens diverges light with a negative focal length, with one side flat and the other concave. It is often used for beam expansion, projection and focal length enlargement of optical system. we provides uncoated, anti-reflection film coated flat - concave lens.
Double-Concave Lens

Double-Concave Lens

市场价:0.00

价格:0.00

 Biconcave lens is similar to a plano-concave lens in that the focal length is negative, which can cause the rays of parallel incidence to diverge outwards.
Powell Lens

Powell Lens

市场价:0.00

价格:0.00

 Powell lens is used to generate straight line. With aspherical curvature on its apex, the output line from powell lenses is even distribution of energy. For comparision, Cylindrical lenses generate gaussian beam profiles with hot-spot centre points and fading edges. The uniformity of output line is also related with incident wavelength, beam size, divergence, and working distance. To get even distribution of energy, The apex curvature need to be slightly modified and optimized for particular laser beam.
Rob Lens

Rob Lens

市场价:0.00

价格:0.00

 Optical rod lens are mainly used to change the size of imaging design requirements. For example, to convert a spot spot into a line spot, or to change the height of an image without changing its width. Applications in linear detector lighting, bar code scanning, holographic lighting, optical information processing, computers, laser emission.
Double-Convex Lens

Double-Convex Lens

市场价:0.00

价格:0.00

 The double convex lens has two convex surfaces with the same radius of curvature, including the incident surface and the radial surface.Double convex lenses are used to concentrate light from point sources or to transfer images to other optical systems.Also used in many limited imaging applications, the double convex lens has symmetry, can make the spherical aberration to minimize, and eliminate the comet, distortion.
Concave-Convex Lenses

Lens

市场价:0.00

价格:0.00

 Concave-convex lenses are also called meniscus lenses. The lens has an external convex surface and an internal concave surface. If the radians outward are greater than the radians inward, the lens has a regular focal length and is used as a magnifying glass.
Achromatic Lens

Achromatic Lens

市场价:0.00

价格:0.00

 Achromatic doublet lens is a combination of a positive lens with a low refractive index (corona glass) and a negative lens with a high refractive index (flint glass).
Aspherical Lens

Aspherical Lens

市场价:0.00

价格:0.00

 Aspheric lens, the radius of curvature varies with the center axis, to improve optical quality, reduce optical elements, reduce the design cost. Aspherical lens has unique advantages over spherical lens, so it has been widely used in optical instrument, image and optoelectronic industry, such as digital camera, CD player，bar code scanners, laser diode collimation， high-end microscopic instrument etc.
Plano-Convex Cylindrical Lens

Cylindrical Lens

市场价:0.00

价格:0.00

 Cylindrical lenses are used for applications that require a point light source to be reshaped in one dimension. A single cylindrical lens is used to convert a collimator laser beam into a linear beam. A pair of cylindrical lenses can be used to shape an image.
Neutral Density Filter

Filter

市场价:0.00

价格:0.00

 Neutral density filters (ND filters) are commonly used in imaging or laser applications to avoid damage to camera sensors or other optical components caused by strong light. An ND filter absorbs or reflects untransmitted light to evenly reduce the transmittance of a portion of the spectrum.
Flat Mirror

Mirror

市场价:0.00

价格:0.00

 Flat Mirrors are Optical Mirrors designed for a variety of applications, including beam steering or folding, interferometry, or as optical components within imaging systems. Additionally, Flat Mirrors are ideal for lab or OEM integration. Surface flatness is a measurement of the roughness of the surface. High surface flatness decreases the amount of light lost through dispersion.
BeamSplitters

BeamSplitters

市场价:0.00

价格:0.00

 Cube Beamsplitters are a type of Beamsplitter used in many life science or laser applications. Cube Beamsplitters are used to split incident light into two separate components. Cube Beamsplitters are durable, easy to mount Beamsplitters that feature equal optical path lengths.
Flat Window

Window

市场价:0.00

价格:0.00

 Planar window is a kind of parallel planar plate, which is usually used as a protective film for electronic sensors or external environment detectors. We can provide window plate of various materials, including colorless optical glass, fused quartz, CaF2, MgF2, Si, Ge, ZnSe, etc. Windows are generally coated with anti-reflection film to reduce reflection, we can also provide a variety of coating services.
