Excimer Laser Focusing Lens 99.9mm Focal Length

NEDL-30-100P

main product photo
These lenses are manufactured with a synthetic fused silica material and it has a high transmittance value in the ultra-violet wavelength of 180 − 400nm. They have excellent performance and are ideal for focusing and imaging applications. There is no adhesive or heat absorption material used to produce these lenses, as a result they show high resistance to the ultraviolet light.
◦They are made of 2 or 3 spherical lenses and they offer correction on spherical and comatic aberration.
◦Standard focal lengths for Excimer laser with 248nm, 266nm and 355nm.
◦NA 0.1 or below (ETL model NA 0.25) can be focused to the diffraction limit.

Guide
  • Products that are not listed in the table or in the catalog such as high pulse lasers or different wavelengths are available upon request, please contact our Sales Division.
  • Protective Windows is sold separately.
    • WEB Reference Catalog Code/W3081
  • For detail on focal length of each wavelength, please see “wavelength characteristic of the focal length data” on “Technical Data”.
Remark -
Attention
  • These focusing lenses are made for use to image an object located in an infinitive distance or using a point of source as a parallel light.
  • The correct direction to input a parallel light is the side with barrel lettering. If the direction is wrong, the spherical aberration will be increased and the image unfocused.
  • If Focusing lens is used with the designed wavelength the spherical aberration and transmission will be poor.
  • Usage with high power laser or near a high temperature light source, the high heat build-up in the lens may alter the focal length. To avoid this, heat prevention is required.
  • To reduce the focus spot size, ensure that the input beam diameter (1/e2) is reduced to half of the effective diameter of the focus lens.
  • These focusing lenses are not chromatic lenses; they are not optically corrected.
  • The lenses have 4% of reflectivity per surface; therefore about 20% of loss is expected in transmission.
