After coating optical devices, the reflection within a specific wavelength range can be minimized. It is usually required that the thickness of the coating must be an odd multiple of 1/4 of the designed wavelength. This design results in a half-wavelength path difference between the reflected beams of two adjacent surfaces, thereby reducing the impact of reflection. The common anti-reflective coating material used by LBTEK is magnesium fluoride (n=1.38), and other anti-reflective coating materials can also be customized.\u003C/span>\u003C/span>\u003C/p>\n\u003Cp class=\"MsoNormal\" style=\"text-align: justify; line-height: 1.75;\" align=\"justify\">\u003Cspan style=\"font-family: 微软雅黑; color: #333333; letter-spacing: 0pt; font-size: 10pt; background: #ffffff;\">\u003Cspan style=\"font-family: 微软雅黑;\">V.

Generally, when the conjugate ratio is greater than 5:1 or close to infinite conjugation (collimated light at one end of the lens), plano-convex/concave lenses or achromatic cemented lenses will be a better choice. When the finite conjugate ratio is between 5:1 and 1:5, the use of double-convex/concave lenses will be more ideal.\u003C/span>\u003C/span>\u003C/span>\u003C/p>\n\u003Cp class=\"MsoNormal\" style=\"text-align: center; line-height: 1.75;\">\u003Cspan style=\"font-family: 微软雅黑; color: #333333; font-size: 10pt; background: #ffffff;\">\u003Cspan style=\"font-family: 微软雅黑;\">Table\u003C/span> 1 Comparison of the effects of different lens shapes\u003C/span>\u003C/p>\n\u003Cp class=\"MsoNormal\" style=\"text-align: center; line-height: 1.75;\">\u003Cspan style=\"font-family: 微软雅黑; color: #333333; font-size: 10pt; background: #ffffff;\">\u003Cimg src=\"https://images.lbtek.com/FnaUP9YEW0TffWJigh6QCY9GnY4k\" width=\"600\">\u003C/span>\u003C/p>\n\u003Cp class=\"MsoNormal\" style=\"text-align: justify; line-height: 1.75;\" align=\"justify\">\u003Cspan style=\"font-family: 微软雅黑; color: #333333; letter-spacing: 0pt; font-size: 10pt; background: #ffffff;\">\u003Cspan style=\"font-family: 微软雅黑;\">VI.

The collimated laser output from the optical fiber is expanded based on the beam magnification ratio Ratio=D/d. By selecting the focal lengths of the plano-concave and plano-convex lenses according to the schematic diagram, the relationship between focal lengths f1 and f2 must satisfy Ratio=D/d=f2/f1 to achieve beam expansion. If beam reduction is required, the optical path should be reversed in the schematic, with the lens focal length ratio satisfying Ratio=d/D=f1/f2. The optical system employs LBTEK standard lens mounts, rod holders, and bases, with standard Ø6mm rods at the top to ensure the optical axes of both lenses are aligned at the same height.\u003C/p>",{"productTabNameId":153,"tabName":869},"Application",["Reactive",871],{"$snuxt-i18n-meta":872},{},["Set"],["ShallowReactive",875],{"$fvpUpa8LH8tCwp-18lSLZ5DkPh0mhQrRmdb45RQuidoo":-1,"$fKUUIOjAeSHVCatg9x5tBVcMjPfqAmR42SkHRWrV1m4k":-1,"$fndpA3AXoqi2i_OEk4bf9b1_8O7QJxpPT3RFp8V0hMZ4":-1},"/product/30?fid=28&tid=45",{"myAppGlobalStore":878,"myAppCartStore":891,"MetayImgPreviewStore":897,"myServiceModalStore":903,"myAppCompareStore":905},{"sessionId":879,"token":880,"surveyLink":882,"navCategory":883,"topAds":886,"feedbackType":888},["Ref",75],["EmptyRef",881],"_",["Ref",74],["Ref",884],["Reactive",885],[14,19,24,29,34,39,44,49,54,59,64],["Ref",887],["Reactive",12],["Ref",889],["Reactive",890],[],{"cartNum":892,"cartData":894},["EmptyRef",893],"0",["Ref",895],["Reactive",896],{},{"visible":898,"previreList":900},["EmptyRef",899],"false",["Ref",901],["Reactive",902],[],{"visible":904},["EmptyRef",899],{"compareIds":906,"compareList":909,"compareVisible":912},["Ref",907],["Reactive",908],[],["Ref",910],["Reactive",911],[],["EmptyRef",899]]
