Achromatic Lenses Cemented Achromatic Doublets Cemented Achromatic Triplets Achromatic Doublet Pairs Air-Spaced Achromatic Doublets Negative Achromatic Lenses Achromatic Cylindrical Lenses Aspherized Achromatic Lenses Near UV Achromatic Lenses Near-IR (NIR) Achromatic Lenses UV-to-NIR Corrected Triplets Mounted Achromatic Pairs -- +1 Cemented Achromatic Doublets Achromatic lenses consist of two optical components cemented together to form an achromatic doubled, which is computer optimized to correct for on-axis spherical and chromatic aberrations. +2 Cemented Achromatic Triplets An achromatic triplet is the simplest lens that corrects all primary chromatic aberrations. These triplets consist of a low-index center element cemented between two identical high-index outer elements and feature good on-axis and off-axis performance. +3 Achromatic Doublet Pairs Worldhawk offers Matched Achromatic Pairs for use in the visible or NIR spectral range. Matched Achromatic Pairs are ideal for image relay, NA conversion, or image magnification. +4 Air-Spaced Achromatic Doublets Worldhawk' selection of air-spaced achromatic doublets offer diffraction-limited spot size, superior aberration correction, and higher damage thresholds than traditional cemented doublets. They have been designed for use across broad wavelength ranges with minimal aberrations. +5 Negative Achromatic Lenses Consisting of two optical elements cemented together, negative achromats are corrected for color and on-axis aberrations. Used predominantly as Barlow lenses to extend focal lengths, they are often combined with positive achromatic mirror systems and imaging lenses.

Product application introduction:

◇Laser module include Line Laser Module, Cross Line Laser Module, Dot Laser Module; Red laser module, Blue laser module, Green laser module. Can be used in Industrial marking devices, laser medical equipment, stage lighting and laser targeting devices, Machine vision, Laser Positioning Surveying Instrument, Laser Sight and so on.

◇Optical Filters are used in applications such as fluorescence microscopy, clinical chemistry, spectroscopy, or machine vision inspection. Including Cut off filter, Bandpass filter, Narrow bandpass filter, Longpass filter, Shortpass filter, ND filter, Notch filters and Color glass filter.

◇Collimator lens also called Aspheric lens, Focusing lens. Eliminate monochromatic aberrations (e.g. spherical aberration) and improve focusing and collimating accuracy. The whole system will be smaller and lighter, and possibly cheaper than the multi-lens design.

◇Sapphire Glass Dome Lens Cover and H-K9L Domes Lens Cover are ideal for commercial applications requiring a protective boundary between two environments. Performing as windows, these N-BK7 glass domes allow you to easily protect electronic sensors or detectors without sacrificing field of view. Glass Domes offer superior optical characteristics.

◇Doublets can come in many forms, though most commercial doublets are achromats, which are optimized to reduce chromatic aberration while also reducing spherical aberration and other optical aberrations. The lenses are made from glasses with different refractive indices and different amounts of dispersion. Often one element is made from crown glass and the other from flint glass. This combination produces a better image than a simple lens. Some Trilobites, which are now extinct, had natural doublet lenses in their eyes. Apochromats can also be made as doublets.
