Optical Filters
When a laser source generates a laser beam, which is a monochromatic light beam defined as a prominent spectral line with a single output wavelength, the presence of minor transitions, plasma, and "glows", all of which lead to background aberrations are impossible to neglect. That’s why it is vital to obliterate all unwanted laser background scatter, and plasma in order to maximize signal-to-noise ratio. Laser Line Filters are effective components when rejecting unwanted disruptions and cleaning up the signals at the laser source. Laser Line Filters are precision optical filters engineered to exhibit high transmission at the laser's emission wavelength(s) while providing excellent attenuation outside of this range., isolating the laser line from ambient light, and attenuating the undesired background plasma and inferior emissions that often cause signal distortions.
Hangzhou Shalom EO offers Standard and Custom Laser Line Filters optimized for various laser types including N2, XeF, Ar, Nd-YAG, GaAIAs, HeNe, etc., with high peak transmissions, and large temperature operation range from -50℃ to 80℃ to withstand turbulent thermal conditions. In addition, utilizing state-of-the-art technologies in the manufacturing procedure, our filters feature high transmission within the pass band, sharp spectral cutoff, narrow transmission bandwidths, and high optical density, minimizing signal loss and maximizing the intensities of the transmitted laser light. The center wavelengths of our standard laser line filters extend from UV to the IR spectral region, covering numerous laser wavelengths, while other custom wavelengths can also be tailored. As a convergence of forward dielectric interference coating techniques, extensive wavelength coverage, and good durabilities, our laser line filters cater to a diverse range of applications including Laser-based spectroscopy, confocal microscopy, flow cytometry, fluorescence imaging, etc.
Besides the listed stock modules, we also offer customization services upon your request. Please contact us for further discussion, our experienced team is willing to exploit our expertise to help you in every step of your project.
