Ultraviolet Achromat Mounted 149.7mm Focal Length

NUDL-50-150P

These lenses contain elements which have different refractive indexes and produce a high degree of correction across a bandwidth of 200 - 400nm. They can be used as a laser focusing lens for broadband ultra-violet sources.
◦NA 0.1 or below (ETL model NA 0.25) can be focused to the diffraction limit.
◦ No adhesive or heat absorption materials are used to produce these lenses and they show high resistance to ultra-violet light.
◦These are not achromatic corrective but offers correction on spherical and comatic aberration.

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.
  • We can provide catalog and custom lenses in large volume to your specifications.
  • For details on focal length of each wavelength, please see details on “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 3 to 4% of reflectivity per surface; therefore about 13% of loss is expected in transmission.
