Asphericon beam shaping mirror，320~1600nm， high damage threshold

GermanyAsphericon GmbHProductiveAsphericonBeam shaping mirror wavelength coverage320 nm-1600 nmAnd its high-precision installation, always perfectly aligned, can reach the wavefront diffraction limit. Can be used in conjunction with a focusing lens to focus and form flat top light. It can also generate circular beams and focused light spots (the size of the light spot is proportional to the focal length). The generation of different light beams depends on the quality of the input light beam, and the damage threshold of the components is high. suchAsphericonBeam shaping mirror, also known as beam shaper, flat top circular beam shaping mirror, Airy beam shaping mirrorAsphericonBeam shaper, Airy beam shaper, beam shaper mirror, multifunctional beam shaper mirror, flat top circular ring beam shapera|Airy∫hapePlastic surgery equipment, etc.

AsphericonCharacteristics of beam shaping mirror:

-It is a multifunctional beam shaper that can generate different beam profiles (such as flat top beam, circular beam, focused beam)

-Spot size can be easily scaled by focal length

-Achieve perfect alignment through high-precision installation and easily integrate into existing devices

-Spectral range:320~1600nm

-High damage threshold

-Lightweight, small in size, easy to integrate

The principle of generating different beam profiles (such as flat top light, circular beam, focused beam) is shown in the following figure, which is different from ordinary flat top lightDOEThe mechanism is completely different:

The characteristics of Asphericon beam shaping mirrors determine that they can not only generate a flat top beam profile within a certain range of the focal plane of the focusing lens, but also create various profiles at different working distances to improve flexibility, representing the beam effect at different focal lengths from left to right. The first, third, and fifth columns in the figure represent the ability of the beam shaper to form a flat topped beam within a certain range（And flat top lightDOEOnly flat top light can be formed at a specific focal plane position）； The second column of the above figure represents that the light spot can be a circular ring light spot, and the fourth column represents that a focused light spot can be formed at the beam waist. This provides great flexibility for customers' use, as a module can be used for more purposes.

Whether the shown beam profile can be generated depends on the quality of the input beam. To achieve the best results, it is required to use a perfectly collimated beam with minimal wavefront aberration (i.eMSmall and accurately incident light. The above figure shows the system structure (focusing structure) of a typical multifunctional beam shaping mirror. What is the contour of the generated light spot?

The Asphericon beam shaper is designed to be compact, with a length of only 17.3 Millimeter, lightweight, can be easily integrated into existing (or even non system) settings. Due to its clever optical design, it can also reduce the working distance. The dimension diagram is as follows:
