These YAG lenses range in
focal length from 20mm to 150mm. They consist of either two or three air-spaced
glass elements mounted in a metal cell. The lenses all have a 30mm clear
aperture but they are recommended for use with beams not exceeding one inch in
diameter. Two different designs are used - the 20, 30, 40 and 50mm focal length
lenses have three elements, but the 60, 80, 100 and 150mm lenses use simpler
two element designs. These lenses are anti-reflection coated with a
laser-resistant narrowband multilayer anti-reflection (NMAR) coating optimized
to give less than 0.5 % reflectance per surface at 1064nm.
These lenses are
chromatically corrected so that a HeNe guide beam or a visible range video
monitor beam will be in focus at the same position as the YAG beam.
Spot size or beam waist is
inversely proportional to the numerical aperture at the effective beam
diameter. The spot size given in the table is for a full aperture beam. Let us
know your imaging requirements and we will be pleased to advise you on the
appropriate lens for your application.
Since these lenses are
often used with high power lasers we offer optional protective windows which
can be attached to the focusing side of the lens. In the event of inadvertent
back reflection of high energy beams into the lens it is likely that the window
will absorb the incident energy and shatter preventing further damage to the
lens itself. Protective windows are offered in packages of 10 pieces.

While these lenses are
intended for use with YAG lasers operating at the fundamental frequency, the
High Power Air Spaced Laser Achromats are ideal for use with frequency doubled
YAG lasers.
