Precision Aplanatic
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 asina kukwirwa achromatic doublet & triplets line-up, tinogona kupa achromatic doublets (ese ari maviri akajairwa uye akajeka aplanatic), cylindrical achromatic doublets, achromatic doublet pairs izvo zvakagadziridzwa kune anogumira conjugates uye akanakira mufananidzo relay uye magnification masisitimu, air-spaced achromatic doublets. izvo zvakanakira maapplication epamusoro-simba nekuda kwekukuvadza kukuru kwechikumbaridzo pane simende achromats, pamwe neachromatic triplets inobvumira kunyanyisa kutadza kutonga.

Paralight Optics 'Precision Aplanats (Aplanatic Achromatic Doublets) haingogadziriswi chete kune spherical aberration uye axial ruvara seStandard Cemented Achromatic Doublets asi zvakare yakagadziriswa pakoma.Musanganiswa uyu unovaita aplanatic mune zvakasikwa uye inopa zvirinani optical performance.Iwo anoshandiswa se laser inotarisisa zvinangwa uye mune electro-optical & imaging masisitimu.
