Hastings Cemented
Achromatic Triplets
Achromatic triplets ine yakaderera-indekisi korona yepakati chinhu chakaiswa pakati pezvinhu zviviri zvakafanana zvakakwirira-indekisi yekunze. Aya matatu matatu anokwanisa kugadzirisa zvese axial uye laterial chromatic aberration, uye symmetric dhizaini yavo inopa yakakwidziridzwa mashandiro ane simende maviri.
Hastings achromatic triplets yakagadzirirwa kupa isingaperi conjugate ratio uye inobatsira kutarisa matanda akasanganiswa uye kukudza. Mukusiyana, Steinheil achromatic triplets yakagadzirirwa kupa inogumira conjugate reshiyo uye 1: 1 imaging. Paralight Optics inopa zvese Steinheil uye Hastings achromatic triplets ine antireflection coating ye400-700 nm wavelength renji, ndapota tarisa inotevera girafu kune ako mareferensi.
Features:
AR Coating:
AR Yakavharidzirwa ye400 - 700 nm Range (Ravg<0.5%)
Benefits:
Yakanakira Muripo weLateral uye Axial Chromatic Aberrations
Optical Performance:
Yakanaka On-Axis uye Off-Axis Kuita
Applications:
Yakagadzirirwa Infinite Conjugate Ratios
Zvakajairwa Zvinodiwa:
