Achromatic Doublets

Achromatic lens, inozivikanwawo seachromat, inowanzo umbwa nezvikamu zviviri zvemaziso zvakabatanidzwa pamwe chete, kazhinji chinhu chakanaka chepasi index (kazhinji girazi regirazi biconvex lens) uye negative high index element (senge girazi redombo). Nekuda kwemusiyano wemaindices erefractive, kuparadzirwa kwezvinhu zviviri izvi zvishoma kunotsiva kune chimwe nechimwe, chromatic aberration maererano nemawavelength maviri akasarudzwa akagadziriswa. Iwo akagadziridzwa kuti agadzirise kune ese ari-axis spherical uye chromatic aberrations. Iyo Achromatic lens ichapa diki diki saizi uye yemhando yepamusoro yemufananidzo pane inofananidzwa singlet lens ine yakafanana focal kureba. Izvi zvinoita kuti ive yakanaka yekufungidzira uye Broadband inotarisa maapplication. Achromats akagadzirwa uye akagadzirwa kuti agutse zvakanyanya kuomesesa kushivirira kunodiwa mune yanhasi yepamusoro-inoshanda laser, electro-optical uye imaging masisitimu.

Paralight Optics inopa akasiyana echinyakare achromatic optics ane mutengi-akatsanangurwa saizi, yakatarisana kureba, substrate zvinhu, simende zvinhu, uye machira anogadzirwa-akagadzirwa. Malenzi edu achromatic anofukidza 240 - 410 nm, 400 - 700 nm, 650 - 1050 nm, 1050 - 1620 nm, 3 - 5 µm, uye 8 - 12 µm kureba kwemasaisai. Iwo anowanikwa asina kukwirwa, akaiswa kana ari anoenderana mapeya. Nezve isina kukwirwa achromatic doublets & triplets line-up, tinogona kupa achromatic doublets, cylindrical achromatic doublets, achromatic doublet pairs dzakagadziridzwa kune anogumira conjugates uye yakanakira mufananidzo relay uye magnification masisitimu, mhepo-yakaparadzaniswa achromatic kaviri ayo akakodzera kune yakakwirira-simba. zvikumbiro nekuda kwekukuvadza kukuru kwechikumbaridzo kupfuura simende achromats, pamwe neachromatic triplets inobvumira kunyanyisa kutadza kutonga.

Paralight Optics 'cemented Achromatic Doublets anowanikwa aine antireflection coatings enzvimbo inoonekwa ye400 - 700 nm, yakawedzerwa inooneka dunhu re400 - 1100 nm, pedyo neIR dunhu re650 - 1050 nm, kana IR renji ye1050 - 1700 nm waveleng. Iwo akagadziridzwa kuti ape kuita kwakanakisa munzvimbo dzinoonekwa uye dziri pedyo-infrared (NIR), iyo yakawedzera antireflection (AR) coating inoita kuti ive yakakodzera kune fluorescence microscopy application. Ndokumbira utarise girafu rinotevera remajeti kune ako mareferensi. Achromatic doublets anoshandiswa sezvinangwa zveteresikopu, ziso reziso, magirazi ekukudza uye ziso. Achromatic doublets yakashandiswawo kutarisa uye kunyengedza laser matanda nekuti iwo mufananidzo mhando yepamusoro kune imwechete lenzi.
