For specified Vs, find such a distance z and beam quality M2 at which the wavefront ROC keeps its previously calculated value.

Cylindrical lenses converge or expand light in a single dimension to alter the proportions of an image, focus a beam to a thin line or generate a line output. CVI Laser Optics offers both plano-convex and plano-concave cylindrical lenses in N-BK7 and UV grade fused silica, in addition to custom lenses. Our laser quality cylindrical lenses are manufactured with low wedge, high surface accuracy and quality, and high laser damage threshold for demanding laser or performance-critical tasks. Our standard-grade lenses are designed to offer excellent performance value for applications where lens wedge and surface accuracy are not critical. Rectangular and square cylindrical lenses are available to address most needs with a standard solution.

Lock front - find such values of free parameters at which the wavefront ROC R and the beam radius w at some axial distance z stay constant when one of the parameters changes.

Cylindricallens vs spherical lens

Lock waist - find such values of free parameters at which the beam waist w0 stays constant when one of the parameters changes.

** y direction is the direction perpendicular to the cylindrical axis, i.e., the cylindrical surface has a radius in this direction

The tool Gauss Beam Calculator computes some free parameters of the Gaussian beam when changing one of its parameters and fixing some others. As it is not possible to make all the parameters to be free, we introduce two fixing modes called Lock waist and Lock front.

How to find z: express w02 from formula for R(z), substitute the expression into formula for w(z) and solve it against z.

Assigning either real or imaginary part of complex beam parameter, we define both the beam radius w and the wavefront ROC R at the same time.

Changing of real part is equivalent to changing of wavefront ROC R, and changing of imaginary part is equivalent to changing of beam radius w.

For specified waist radius w0, find such a distance z and beam quality M2 at which the wavefront ROC keeps its previously calculated value.

How to find z: substitute z0 as w0/Vs into formulas for w(z) and R(z), express w0 from both, equate them and solve against z.

*** Note: The general tolerance specifications above are intended to guide determination of appropriate tolerances based both on relative cost and manufacturability. Part-specific tolerances will vary depending on size, material, shape and aspect ratio. Tighter tolerances may be possible, so please contact us to discuss your custom specifications. All specifications do not need to be from a single column, though trade-offs may be required in order to meet the desired combination of cost and performance.

Quadratic equations have two solutions and we have to define a way to point out which solution to take. So the tool has one additional parameter - zone - which can be Near zone or Far zone.

For specified z0, find such a distance z and beam quality M2 at which the wavefront ROC keeps its previously calculated value. + sign is for the far zone, - is for the near zone.

High quality antireflection coatings are essential for maximum throughput and power handling, and ours are among the best. We offer a wide variety of coating options including broadband and laser line AR, as well as custom coatings. To achieve the highest laser damage threshold, we typically recommend V-coat antireflection coatings on laser-grade fused silica substrates.

Find beam quality parameter M2 giving specified beam radius at the same axial distance z and with the same waist radius w0.
