Semrock 滤光片 LP02-244RS-25
244 nm RazorEdge® ultrasteep long-pass edge filter
| RazorEdge filters allow you to see the weakest signals closer to the laser line, especially for Raman spectroscopy applications. With their deep laser-line blocking, ultrawide and low-ripple passbands, hard-coated reliability, and high laser damage threshold, they offer lasting performance and value. |
