# IO:I Filter Transmission Data # # Transmission curves for both IO:I filters have been measured in the lab on the bench. # The following data were obtained by the manufacturer at a temperature of 300K. In the # cryostat at operating temperature the transmission curve is shifted slightly to the # blue compared to the data presented here. # # IO:I J Filter # Measured at 300K # Expect approx. 3nm bluewards shift at operating temperature # # Columns: # Wavelength (nm) # Transmission (%) # 1000.4 0.2 1024.0 0.3 1050.1 0.3 1076.5 0.3 1099.9 0.4 1125.6 0.5 1139.0 0.6 1150.1 1.1 1156.4 2.4 1162.1 5.4 1165.8 10.0 1168.0 14.6 1170.2 20.0 1171.3 24.6 1172.9 30.1 1173.7 35.1 1174.8 40.1 1175.9 45.0 1177.0 50.0 1178.0 54.9 1179.3 59.9 1181.8 64.9 1184.7 69.2 1187.1 69.8 1190.6 70.1 1194.0 70.3 1197.4 70.1 1200.5 70.4 1203.8 70.3 1206.9 71.0 1210.2 72.0 1212.6 73.2 1213.8 74.3 1216.4 75.9 1217.4 76.5 1219.3 78.1 1221.7 79.4 1225.4 80.0 1227.3 80.4 1230.4 79.4 1233.6 78.4 1236.7 77.6 1238.9 76.7 1241.2 77.3 1245.2 77.7 1248.6 78.7 1251.0 79.5 1254.1 80.2 1255.4 80.9 1258.2 80.3 1261.0 80.3 1264.8 79.9 1269.2 79.6 1273.3 79.6 1275.9 80.2 1279.4 81.1 1282.0 82.0 1285.8 82.7 1288.3 83.6 1292.8 83.5 1297.3 83.0 1299.4 81.9 1303.6 81.2 1306.5 80.4 1309.3 80.2 1312.4 80.2 1315.4 80.3 1318.3 79.7 1319.4 78.9 1322.3 75.5 1325.4 69.9 1326.9 65.1 1328.4 60.0 1329.7 55.5 1331.2 50.0 1332.6 45.1 1333.8 40.0 1335.1 35.5 1336.5 30.1 1338.1 25.2 1340.2 20.0 1342.4 15.4 1346.5 10.1 1350.1 7.0 1355.5 4.2 1360.8 2.5 1367.5 1.5 1377.3 0.8 1390.1 0.5 1400.0 0.4 1427.6 0.4 1450.0 0.3 1476.6 0.3 1500.0 0.3 # # IO:I H Filter # Measured at 300K # Expect approx. 8nm bluewards shift at operating temperature # # Columns: # Wavelength (nm) # Transmission (%) # 1300.2 0.1 1349.9 0.1 1400.1 0.1 1425.2 0.4 1446.9 1.0 1460.0 2.6 1468.8 5.6 1474.3 9.3 1478.3 14.2 1481.6 19.2 1484.4 25.0 1486.2 30.1 1488.2 35.2 1489.7 40.1 1491.2 44.5 1492.7 50.0 1494.3 55.3 1496.1 59.9 1497.6 64.8 1499.5 68.4 1502.3 74.2 1506.1 78.4 1507.9 80.1 1510.6 81.9 1515.8 83.6 1520.5 85.2 1525.7 86.1 1531.0 87.4 1537.6 88.4 1542.2 88.8 1549.0 89.2 1555.4 89.3 1558.8 89.5 1567.9 89.8 1572.6 90.1 1575.5 90.2 1586.3 90.7 1589.0 90.9 1592.6 91.1 1599.5 91.6 1609.0 91.9 1613.1 92.2 1620.1 92.2 1629.3 91.8 1637.1 90.9 1642.9 89.8 1649.2 88.5 1656.1 87.0 1658.9 86.5 1662.2 86.1 1669.5 85.5 1678.5 85.4 1683.1 85.7 1688.9 86.1 1694.8 86.5 1698.7 86.7 1706.3 86.8 1707.8 86.8 1715.4 86.4 1722.0 86.1 1726.4 85.8 1731.4 85.8 1737.6 85.4 1745.0 84.0 1749.1 82.4 1753.2 80.1 1758.8 75.6 1764.0 70.0 1767.5 65.5 1771.7 60.0 1774.8 55.3 1779.2 50.0 1782.4 45.5 1786.8 40.1 1790.6 35.4 1795.2 30.1 1799.8 25.3 1805.4 20.1 1810.7 15.2 1818.6 10.0 1824.5 7.1 1831.7 5.0 1841.7 3.0 1849.6 2.0 1860.9 1.3 1878.5 0.7 1899.9 0.5 1929.5 0.4 1949.7 0.4 2000.4 0.2
