That is the highest measured transmission point, not automatically a defined centre wavelength or a passband specification. Use the surrounding curve to judge the signal range.\u003c\/p\u003e\n\u003ch3\u003eDoes the 560 designation mean this is a narrow 560 nm bandpass?\u003c\/h3\u003e\n\u003cp\u003eDo not assume a narrow passband from the name. The customer sample-book curve matches the factory BH-A38(BPF560) reference, so this listing follows that measured response. If you need to isolate a narrow 560 nm signal, compare the complete curve and specify the bandwidth and blocking you need.\u003c\/p\u003e\u003c\/section\u003e\u003cp\u003e\u003ca href=\"\/pages\/contact\"\u003e\u003cstrong\u003eDiscuss this filter with KUPO\u003c\/strong\u003e\u003c\/a\u003e - include the product reference, source wavelength, working angle and required dimensions.\u003c\/p\u003e\u003cstyle\u003e#MainContent .ko-reviewed\u003eh2.ko-catalog-description-title{font-size:27px;font-weight:500;line-height:1.4;letter-spacing:-.01em;color:#0c324b;background:#f0f6f9;padding:20px 24px;}#MainContent .ko-reviewed\u003eh2.ko-catalog-description-title+p{border-bottom:0;}@media(max-width:650px){#MainContent .ko-reviewed\u003eh2.ko-catalog-description-title{font-size:24px;}}\u003c\/style\u003e","brand":"KUPO Optics","offers":[{"title":"Broad Bandpass Filter \/ Green","offer_id":48516669899007,"sku":"BBP-560","price":0.0,"currency_code":"TWD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0818\/8651\/1359\/files\/bbp-560-spectrum.jpg?v=1778712921","url":"https:\/\/kupooptics.com\/products\/bbp-560","provider":"KUPO Optics","version":"1.0","type":"link"}
