Alluxa Ultra Narrow Bandpass Optical Filters For Sale

ULTRA-Narrow Bandpass Filters
With the narrowest bandwidths and highest transmission in the industry, Alluxa’s thin-film, ultra-narrow bandpass filters will optimize the performance of laser based systems.

Ultra-narrow filters are ideal for use as laser line, laser cleanup, or laser excitation filters in applications such as fluorescence microscopy, flow cytometry, and DNA sequencing. They are also highly resistant to laser damage, which ensures that they will maintain a high level of performance for a long period of time.

Depending on the wavelength ranges and requirements of your system, ultra-narrowband filters can be custom designed to meet one or more of the following challenging specifications:
•Up to 98% peak transmission
•Up to OD10 blocking by design
•CWL at any wavelength from the UV to the mid IR (~250 nm to 6.2 µm)
•CWL tolerances as tight as 0.05 nm
•FWHM bandwidths as narrow as 0.1 nm
•TWE as low as 0.01 wave RMS / inch measured at 632.8 nm

Flat-top ultra-narrow bandpass filters for precision control
Flat-top, ultra-narrow bandpass filters are specifically designed to have extremely steep edges and high transmission throughout the entire passband. This square spectral shape is able to be achieved for bandwidths as narrow as 0.1 nm. Flat-top narrowband filters are ideal for LIDAR, Raman spectroscopy, and other applications that require the use of precision laser transmitting filters or laser cleanup filters.

Quality and consistency from an innovative thin-film coating process
All of Alluxa's filters are hard-coated using our SIRRUS™ plasma deposition process on equipment that was designed and built by our team. This allows us to reliably and repeatedly produce the same high-performance narrowband filters over several different coating runs, which translates to consistent performance across all of your systems.
