Ultra narrowband filter
Alluxa ultra narrow band filter is at the forefront of the industry, with a FWHM bandwidth as narrow as 0.1 nm and a light transmission rate of over 9
Product details
The FWHM bandwidth is narrow to 0.1 nm, and the optical transmission rate exceeds 90%The filter
Alluxa specializes in precision coating andFlat top ultra narrow bandpass filterUltra narrowband filters have a history of 14 years, during which they have become the world leader in ultra narrowband filters, mainly due to achieving a transmission rate of over 90% and sub nanometer bandwidth. Narrowband filters mainly rely on two indicators: transmittance and bandwidth (FWHM). The strength of Alluxa filters lies in their superior performance compared to other peersThe narrowest bandwidth and highest transmission performance! All of its products have passedISO9001： 2015 certification.
The unique SIRRUS designed and manufactured by the Alluxa team ™ The plasma deposition process was used to hard coat the Alluxa thin film optical interference filter and dielectric electron microscope. This enables Alluxa to reliably and repeatedly produce the same high-performance optical film in multiple different coating processes, achieving consistent performance throughout the entire system.
AlluxaThe principle and application of ultra narrowband filter:
The principle of Alluxa ultra narrow band filter is very complex, mainly processed through microfabrication and precision coating technology on a lens, so that the lens can block some light that does not meet the conditions.
Simply put, the application of ultra narrowband filters is focused on the three words "filter", which filters out unwanted light during use and highlights the light one wants. This is the main application of filters, and their application fields are very wide.
Performance diagram of Alluxa flat top ultra narrow bandpass filter:
↑Flat top ultra narrow bandpass filter with a flat top shape at the top of its passband
Two edges are descending rapidlyThe sidebands are completely suppressed in the visible light region, forming an approximately square passband
The flat top ultra narrow bandpass filter is specially designed to have an ultra fast band edge and high transmittance throughout the entire passband. For narrow toA bandwidth of 0.1 nm can achieve this square spectral shape. Flat top narrowband filters are highly suitable for applications such as laser radar, Raman spectroscopy, and others that require the use of precision laser transmission filters or laser cleaning filters.
