- High Transmission for Detecting Weak Signals
- Deep Blocking for Maximum Laser Rejection
- Ideal for Raman Spectroscopy, Confocal Microscopy, and Biotech Instrumentation
Edmund Optics TECHSPEC® Raman Edge Filters feature steep edges for detecting even the smallest Raman shifts. They are superior alternatives to more expensive holographic notch filters for Stokes Raman scattering measurements. Unlike holographic notch filters, TECHSPEC Raman Edge Filters reflect rejected laser light, reducing issues commonly associated with stray-light measurements, and eliminating the need for complicated light baffling systems. With guaranteed transition widths of less than 1%, angle-tuning is unnecessary, greatly simplifying system setup and implementation.
