雙膠合消色差透鏡 消色差雙膠合透鏡是一種把低分散的冕牌玻璃正透鏡和高分散的火石玻璃負透鏡粘接而成的消色差透鏡。和單個透鏡相比，消色差雙膠合透鏡的球差要小得多。使用于無限共軛狀態(tài)時，其球差較小。 產(chǎn)品參數(shù)： 尺寸容差：+/-0.15mm 表面精度：λ/4 @632.8nm 光潔度：40-20 中心偏差：<3 arc min 通光孔徑：>90% 倒邊：0.25mm×45° Part Number D(mm) EFL(mm) Tc(mm) Te(mm) BFL(mm) LOADL5-7.5 5.00 7.50 4.50 3.70 5.20 LOADL5-10 5.00 10.00 4.40 3.70 7.90 LOADL5-15 5.00 15.00 4.80 4.30 13.60 LOADL6-10 6.00 10.00 4.00 3.00 7.90 LOADL6.25-20 6.25 20.00 3.60 3.00 18.23 LOADL6.25-25 6.25 25.00 3.20 2.73 23.45 LOADL6.25-30 6.25 30.00 3.20 2.80 28.43 LOADL8-20 8.00 20.00 4.00 3.00 17.80 LOADL9-27 9.00 27.00 5.19 4.25 24.22 LOADL9-36 9.00 36.00 4.00 3.32 34.17 LOADL9-40 9.00 40.00 5.06 4.45 37.54 LOADL9-45 9.00 45.00 4.30 3.76 42.97 LOADL9-75 9.00 75.00 4.60 4.28 72.35 LOADL12.5-40 12.50 40.00 5.06 3.88 37.54 LOADL12.5-45 12.50 45.00 5.00 3.94 42.52 LOADL12.5-50 12.50 50.00 5.00 4.06 47.61 LOADL12.5-60 12.50 60.00 5.00 4.21 57.59 LOADL12.5-75 12.50 75.00 4.60 4.00 72.35 LOADL12.5-80 12.50 80.00 3.70 3.12 78.40 LOADL12.5-90 12.50 90.00 3.58 3.06 88.47 LOADL12.5-100 12.50 100.00 4.50 4.03 97.92 Part Number D(mm) EFL(mm) Tc(mm) Te(mm) BFL(mm) LOADL12.7-25 12.70 25.00 5.60 4.80 22.25 LOADL12.7-30 12.70 30.00 5.30 4.75 27.36 LOADL12.7-40 12.70 40.00 4.70 3.90 37.78 LOADL12.7-50 12.70 50.00 4.40 3.79 48.00 LOADL12.7-60 12.70 60.00 4.10 3.80 58.13 LOADL12.7-75 12.70 75.00 3.90 3.40 73.23 LOADL15-50 15.00 50.00 6.50 5.12 46.17 LOADL15-75 15.00 75.00 7.50 6.59 70.78 LOADL18-80 18.00 80.00 7.50 6.27 76.52 LOADL18-125 18.00 125.00 6.50 5.72 121.95 LOADL20-60 20.00 60.00 7.00 4.98 56.51 LOADL25-75 25.00 75.00 9.50 6.97 70.39 LOADL25-100 25.00 100.00 8.50 6.61 81.21 LOADL25-125 25.00 125.00 8.40 6.90 120.89 LOADL25-150 25.00 150.00 7.90 6.60 146.10 LOADL25-175 25.00 175.00 9.00 7.90 170.84 LOADL25-200 25.00 200.00 12.50 11.56 194.14 LOADL25-250 25.00 250.00 7.50 6.75 246.63 LOADL25-275 25.00 275.00 7.50 6.82 271.60 Part Number D(mm) EFL(mm) Tc(mm) Te(mm) BFL(mm) LOADL25-300 25.00 300.00 5.50 4.89 297.73 LOADL25-400 25.00 400.00 5.50 5.02 397.84 LOADL25-500 25.00 500.00 5.50 5.13 497.57 LOADL25.4-40 25.40 40.00 12.50 7.40 33.40 LOADL25.4-60 25.40 60.00 10.50 8.20 54.30 LOADL25.4-75 25.40 75.00 9.50 6.90 70.30 LOADL25.4-100 25.40 100.00 6.50 4.70 97.10 LOADL25.4-150 25.40 150.00 7.90 6.60 146.10 LOADL25.4-250 25.40 250.00 6.00 5.20 246.70 LOADL30-100 30.00 100.00 11.05 8.31 94.54 LOADL30-150 30.00 150.00 10.70 8.88 144.63 LOADL30-200 30.00 200.00 7.50 6.15 196.57 LOADL30-300 30.00 300.00 7.00 6.10 296.85 LOADL40-160 40.00 160.00 12.50 9.48 154.10 LOADL40-200 40.00 200.00 12.50 10.09 194.20 LOADL40-250 40.00 250.00 12.50 10.57 244.32 LOADL40-400 40.00 400.00 12.50 11.30 394.33 LOADL40-500 40.00 500.00 10.00 9.04 497.60 LOADL50-500 50.00 500.00 12.00 10.50 494.50 LOADL50.8-150 50.80 150.00 15.00 9.70 141.00 Part Number D(mm) EFL(mm) Tc(mm) Te(mm) BFL(mm) LOADL50.8-200 50.80 200.00 10.50 6.70 193.70 LOADL50.8-250 50.80 250.00 9.50 6.40 244.60 LOADL50.8-300 50.80 300.00 8.00 5.40 295.40 LOADL50.8-400 50.80 400.00 7.00 5.10 396.10 LOADL50.8-500 50.80 500.00 7.00 5.50 495.80 LOADL50.8-750 50.80 750.00 6.50 5.50 746.50 LOADL50.8-1000 50.80 1000.00 6.00 5.20 994.60 LOALDN12.7-25 12.70 -25.00 1.50 2.50 -26.61 LOALDN12.7-30 12.70 -30.00 1.50 2.60 -41.56
