Beam Expander - What You Should Know About It

What is an achromatic lens?

An achromatic lens or Achromat is a lens that is created for the purpose of restricting the consequences of lens(chromatic and spherical) aberration. Achromatic lenses have been adjusted to bring two wavelengths to concentrate in the exact same plane.

What's a chromatic aberration?

Chromatic aberration, too Called chromatic distortion and spherochromatism, is a result caused from dispersion as a result of failure of a lens to focus all colors to the same convergence point. When white light passes through glass, every wavelength element of the light is separated and concentrates at different points onto a plane. Chromatic aberration seem as "fringes" of color combined boundaries that separate bright and dark parts of the image, due to each colour in the optical spectrum cannot be focused at one common point.

What's a spherical aberration?

Spherical aberration is an Optical effect that happens in a lens due to the increase of refraction of light rays as soon as it strikes the lens. The generated image will end in imperfection. Both this phenomenon suggests that the lens is not working normally.

Achromatic double lenses

Achromatic doublet is your Most frequent type of achromat lens. Generally, it consists of 2 separate lenses made from glasses with various amounts of dispersion.

Achromatic lenses utilize 2 Different glass substances of different dispersion to refocus the individual wavelengths of light into one focal point.

Achromatic lenses may be Used to adjust the line of sight and focus laser beams. These lenses are commonly utilized in high quality digital imaging, surface inspection, and spectroscopy applications.
