Laser filters are used to transmit the wavelengths required for various laser applications while rejecting one or more wavelengths. Laser filters are created utilizing different substrates, coatings, or a mix of both to reflect a certain range of wavelengths while transmitting all other light. Optical filters like bandpass, longpass, and notch are examples of laser filters. Dichroic filters come in a variety of sizes and can be used to choose a specific wavelength or transmission width.
Alfa Chemistry offers a wide range of laser filters to fit the needs of many laser systems. In a particular wavelength band, we have neutral density filters with flat transmission properties. Additionally, band-pass filters, which omit out-of-band spectral components while selectively transmitting a particular wavelength range.
All wavelengths within a certain range are reflected by long-pass filters, while all wavelengths outside of that range are transmitted. All wavelengths below or above the cutoff point are transmitted via notch filters while a limited range of wavelengths are selectively reflected. For isolating a very particular range of wavelengths, trap filters are perfect.
In addition we can also customize filters on request. If you don't find what you have been looking for, please feel free to contact us.
