CNC-yakakwenenzverwa kana MRF-yakakwenenzverwa Aspheric Lenses

Aspheric lenzi, kana aspheres akagadzirwa kuti ave nefocal kureba kupfupi pane zvinogoneka neagara ari spherical lenzi. An aspheric Lens, kana asphere inoratidzira nzvimbo ine radius inoshanduka nechinhambwe kubva kune optical axis, ichi chakasarudzika chinobvumira aspheric lenzi kubvisa spherical aberration uye kuderedza zvakanyanya kumwe kukanganisa kuitira kuendesa kwakavandudzika kuita kwemaziso. Aspheres yakanakira laser yekutarisa maapplication sezvo ivo vakagadziridzwa kune diki nzvimbo saizi. Uye zvakare, imwe aspheric lens inogona kazhinji kutsiva akawanda spherical zvinhu mune yekufungidzira system.

Sezvo aspheric lenses akagadziridzwa kune spherical uye coma aberrations, iwo akanyatsokodzera yakaderera f-nhamba uye yakakwirira throughput application, condenser quality aspheres inonyanya kushandiswa mumhando yepamusoro yekuvhenekera masisitimu.

Paralight Optics inopa CNC chaiyo-yakakwenenzverwa yakakura-diameter aspherical lenzi, ine uye isina anti-reflection (AR) machira. Aya malenzi anowanikwa muhukuru hukuru, anopa zvirinani pamusoro pemhando, uye chengetedza iyo M squared values ​​yedanda rekuisa zviri nani pane avo akaumbwa aspheric lens mamwe. Sezvo pamusoro peaspheric lens yakagadzirirwa kubvisa spherical aberration, ivo vanowanzo shandiswa kubatanidza mwenje unobuda mu fiber kana laser diode. Isu tinopawo acylindrical lenses, iyo inopa zvakanakira aspheres mune imwe-dimensional yekutarisa maapplication.

Kupi:
Z = Sag(Surface Profile)
Y = Radial Distance kubva kuOptical Axis
R = Radius yeCurvature
K = Conic Constant
A4 = 4th Order Aspheric Coefficient
A6 = 6th Order Aspheric Coefficient
An = nth Order Aspheric Coefficient
