Ondax CleanLine™ Series ASE Filter Systems are a family of tightly integrated, pre-aligned, multi-element ASE Filter Modules designed to provide the enhanced narrow band, low noise, ASE-free laser performance required for ultra-low-frequency (low wavenumber) Raman spectroscopy, and other demanding spectroscopy or metrology applications. Configured for fast, easy alignment and use with our SureBlock™ XLF Series Raman Filter Systems, the CleanLine™ family is based on our proprietary NoiseBlock™ solid-state, ultra-narrow band Volume Holographic Filter technology, delivering unlimited lifetime, exceptional throughput, and ultra-stable environmental performance.

The CleanLine™ FS is an ultra-compact (3” or 75mm) free-space configuration with integrated alignment irises and a built-in wavelength fine-tuning adjustment. The CleanLine™ LM comes with an integrated SureLock™ LM Series wavelength-stabilized laser module, optical isolator, and fiber-coupling option – ideal for turn-key integration into your Raman system.

Available for standard wavelengths of 785nm, 532nm, and 405nm. Custom wavelengths are available upon request.
