Long wave pass and short wave pass filters (LWP/SWP)

Long wave pass and short wave pass filters (LWP/SWP)

Alkor Technologies can design and fabricate custom infrared bandpass filters to suit your particular requirements. Every phase of the process is performed in-house, including thin-film coating design, mechanical design, substrate fabrication and polishing, coating, inspection.

Optical Bandpass filters isolate specific regions of the spectrum, simultaneously providing high transmission of desired energy, and deep rejection of unwanted energy. Available in broad or narrow bandwidths, they can be tailored to suit your specific requirements. Optical Bandpass Filters are ideal for a variety of applications, spectroscopy, imaging. These filters are typically used in the life science, industrial, or R&D industries.

We can coat a variety of substrate materials, including Germanium, Sapphire, Silicon, Zinc Sulfide, and Zinc Selenide. Contact us today with your custom IR filter specifications!

Short-wavelength blocking filters are designed and manufactured to pass the long-wave radiation and to block short-wavelength radiation.
