THz-Raman Filter Components


With improved performance over thin film and gel filters, these compact and economical components are ideal for creating high-performance custom systems with access to low frequency Raman spectra < 150 cm-1.

Ideal for academic or OEM applications. Filters come pre-mounted in housings for use with standard 1” or ½" mirror mounts. Compact, pre-aligned assemblies guarantee correct pitch and yaw angle of each filter to deliver fully optimized performance.


THz-Raman® Filter Components Summary

Multiple wavelengths and configuration options are available. All filters use the same technology to produce optimal system performance from a compatible laser.
