488 nm RazorEdge® ultrasteep long-pass edge filter

Semrock Part Number: LP02-488RE-25

IDEX Part Number: FL-009034  /

Semrock
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.
