1064nm F-Theta Inotarisa Lens yeLaser Kumaka

Tsanangudzo Pfupi:

F-Theta lenses - inonziwo scan zvinangwa kana flat field zvinangwa - lens masisitimu anowanzo shandiswa mu scan application.Iri munzira yedanda mushure memusoro we scan, vanoita mabasa akasiyana.

F-theta chinangwa chinowanzo shandiswa pamwe chete negalvo-based laser scanner.Iyo ine 2 mabasa makuru: tarisa iyo laser nzvimbo uye flatte iyo mufananidzo munda, sezvakaratidzwa mumufananidzo pazasi.Iyo inobuda danda kusimuka yakaenzana nef * θ, saka yakapihwa zita rekuti f-theta chinangwa.Nekuunza huwandu hwakatarwa hwekukanganiswa kwedhiramu mune yekuvheneka lens, iyo F-Theta yekutarisa lens inova sarudzo yakanaka kune maapplication anoda nzvimbo yakati sandara pandege yemufananidzo senge laser scanning, kumaka, kunyora uye kucheka masisitimu.Zvichienderana nezvinodiwa zvechishandiso, aya diffraction mashoma lens masisitimu anogona kuvandudzwa kuti averenge wevelength, saizi yemavara, uye kureba kwakatarisana, uye kukanganisa kunobata isingasviki 0.25% munzvimbo yese yekuona lens.
