In addition, Shalom EO also provides abundant choices of lens sizes and focal lengths. Shalom EO supplies a wide range of lens types, including: plano-convex lenses and plano-concave lenses biconvex and biconcave lenses ball and half-ball lenses achromatic doublet lenses meniscus lenses ...

Alternatively, vectored actuation and the manipulation of astigmatism could be directly applied to laser beam shaping, for example, to compensate for thermal drift in the laser cavity which results in a non-uniform irradiation distribution. Furthermore, in ophthalmology, tunable elastomeric lenses lend ...
taking in count the age of the lens and the moderate magnification applied to a 13x18cm plate); stopping down the iris to 17mm we get the best compromise between aberrations suppression and diffraction, and the lens le ts you record a really unexpected resolution, at least in the central a...
To deduce the actual droplet-internal interface location, this correction was applied by first determining the off axis distancehifor each point along the interface in the side view images of the drops using a custom MATLAB algorithm. We then used equation (4) to calculate the real shape of ...
An achromatic objective is corrected for chromatic aberration at the red and blue wavelengths only. 12. Koehler illumination Koehler illumination overcomes the disadvantages of other schemes by causing parallel rays to light the specimen so that, because they will not be in focus, the image of the...
forming a mold having the negative shape of the lens, including a mold portion corresponding to an end surface of the lens and being the negative of the combination of a conic component, a spiral component and a cone component, and producing said lens by a flowable material applied to said...
The laser beam was focused onto the IOL surface using a ×20 achromatic standard objective lens with a numerical aperture (𝑁𝐴NA) of 0.4 (Edmund Optics, Barrington, IL, USA). The beam spot size was ~3.6 μm as calculated by the equation 𝑑=4𝑀2𝜆𝑓/𝜋𝐷0,d=4M2λf/...
