Ultraviolet Achromat Mounted 80.3mm Focal Length

UDL-40-80P

Skip to the beginning of the images gallery

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.

Details

◦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.

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 opposite to the barrel lettering (cf drawing). 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.
