Laser manufacturers use the focus lens in order to adjust the size of the laser so it can travel from the laser head, to the fiberoptic, the handpiece and finally reach the patientâ??s skin. It is very important that the focus lens are spotlessly clean, free of dust and scratches. Dust and scratches on their surface will cause the laser to burn them gradually, prevent full laser emission, and can misdirect part of the laser, which can cause other components to be burned. We strongly recommend keeping the focus lens in good condition. Additionally, keep your work area spotlessly clean in order to avoid dust particles which can be detrimental to aesthetic laser equipment.
These are premium and quality custom made focus lenses that are made exactly by the manufacturers requirements. These focus lenses have been applied with AR coating to achieve optimum durability and transmitting of the laser beam. This will create better treatment results and allow your machine to be more time efficient.
Anti-glare acrylic lens are made of fabricating a super-fine single-matte acrylic sheet,
it creates much better readability of the text, image, and photos for people by reducing the glare, reflection ,and eye dizziness.

Contact lenses are thin, clear plastic disks you wear in your eye to improve your vision. Contacts float on the tear film that covers your cornea.
whose base plate material is PMMA, also known as pressure afterburner lenses, sub-afterburner lenses, in fact, refers to the general term of PMMA sheet after electroplating, using plastic lenses instead of glass lenses, has the advantages of light weight, not easy to break, easy shaping and processing, easy coloring, etc., the momentum of development is increasing, and has become a kind of technology in lens production. Plastic sheets can generally be made into: single-sided mirror, double-sided mirror, taped mirror, paper mirror, semi-lens, etc. can be done according to different requirements. For example, mobile phones and TV screens are visible everyday.
Because acrylic is difficult to produce and its cost is high, there are many substitutes of high quality and low price in the market. These substitutes, also known as acrylic, are actually ordinary organic or composite boards (also known as sandwich boards). Ordinary organic board is cast with ordinary organic glass cracking material and pigment. Its surface hardness is low, and it is easy to fade. After polishing with fine sand, the polishing effect is poor. The composite board has only a very thin acrylic surface and ABS plastics in the middle. It is easy to delaminate due to thermal expansion and contraction in use. The true and false acrylic can be identified from the slight chromatic aberration and polishing effect of the plate section.

3 Optical lens design
3.1Â Zoom lens system is an optical system in which the focal length changes within a certain range and the image plane remains fixed. In general, the relative aperture is constant during zoom.For imaging system, continuous zoom optical system is the best way to solve the problem of large field search and small field resolution. The ratio of the two ultimate focal lengths in the zoom range, namely the ratio of the long focal length to the short focal length, is called magnification ratio, also known as multiplier. In consideration of the secondary spectrum requirements, the plan of the small relative aperture of the long focal length is adopted (that is, the relative aperture also changes during the zoom process).
3.2Â The optical system USES a continuous zoom lens with a focal length of 15mm~300mm.
