Where to Buy Lenses

DPM Photonics offers precision lenses for collimating the output of high power fiber devices. We also sell focusing objective lenses.

The Model 02-014-1 is an air spaced, computer designed multi-element lens that is diffaction-limited when used with fibers having core diameters as large as 1200 microns. Operational wavelength is 1064 nm. The 02-014 reimages the emitting surface of the fiber with a 0.67× demagnification. Focused spot sizes are significantly smaller than those achievable with single-element lenses used in a similar collimating/focusing configuration. All optical elements are fabricated from high laser-damage resistant glasses and are anti-reflection coated to reduce reflectance per surface to 0.13%. The working distance between the lens and the target is sufficiently large to allow use of a gas nozzle to enhance the cutting or welding process and to prevent debris from depositing on the lens surface.

Standard plano-convex, plano-concave, biconvex, biconcave, cylindrical lenses and lens kits made of BK7, UVFS or CaF₂ optical materials. Lenses of custom design can be produced in our CNC lens polishing facility and later coated for your application.

We sell spherical and cylindrical lenses, including plano-convec, bi-convex, bi-concave and meniscus lenses.
