Semrock RazorEdge Raman Filters

Semrock stocks an unsurpassed selection of the highest performance edge filters available for Raman-spectroscopy, with edge wavelengths from 224nm to 1319nm. Now you can see the weakest signals closer to the laser line, than you ever have before. With their deep laser-line blocking, ultra-wide and low-ripple passbands, proven hard-coating reliability, and high laser damage threshold, they offer performance that lasts. Razor Edge filter technology is unique and patented.

• Steepest edges to measure even the smallest Raman shifts
• Deep laser-line blocking for maximum laser rejection (> OD6)
• High signal transmission to detect the weakest signals (>98% typical)
• High laser damage threshold and proven reliability (1 J/cm² for 532nm)
• Rejected light is reflected for convenient alignment and best stray-light control
• UV long-wave-pass filters for wavelengths as short as 224nm

All standard products are in stock at Semrock and can be delivered to Australia/New Zealand within 1-2 weeks.
