邊緣陡度和過渡寬度 Semrock邊緣濾光片-包括我們陡RazorEdge®拉曼濾光片以及用于特定應(yīng)用拉曼系統(tǒng)和熒光成像的EdgeBasic™濾光片,具有經(jīng)保證的“過渡寬度。” 過渡寬度=激光線(OD > 6)和50%透射點(diǎn)之間允許的大光譜寬度 任何給定的濾光片也可以用它的“邊緣陡度”來(lái)描述,這是濾光片的實(shí)際陡度,而不管邊緣的的波長(zhǎng)位置。 邊緣陡度=從OD 6點(diǎn)到50%的透射點(diǎn)的濾光片的實(shí)際陡度 圖1說(shuō)明了用于阻擋785納米激光線的邊緣濾波器的過渡寬度和邊緣陡度(例子顯示u級(jí)的RazorEdge濾光片)。表1列出了Semrock邊緣濾光片的保證過渡寬度和典型的邊緣陡度(25毫米直徑部分)。 所有的RazorEdge濾光片都提供異常的陡度,可以測(cè)量非常接近有著高信噪比被阻塞的激光線的信號(hào)。然而,的e級(jí)RazorEdge濾光片接近水平。 右邊的圖說(shuō)明u級(jí)的RazorEdge濾光片的過渡寬度是激光波長(zhǎng)的1%。e級(jí)濾光片的過渡寬度是激光線的兩倍,或者是激光線的0.5%。 Table 1 邊緣濾光片類型 | 保證的過渡寬度 (激光波長(zhǎng)的百分比) | 典型的邊緣Steepness (激光波長(zhǎng)的百分比) | 99 | < 0.5% (< 90 cm-1 for 532) | 0.2% (1.1 nm for 532) | RazorEdge U-grade | < 1.0% (< 186 cm-1 for 532) | 0.5% (2.7 nm for 532) | EdgeBasic | < 2.5% (< 458 cm-1 for 532) | 1.5% (8.0 nm for 532) |
