Semrock Introduces A New Cutting Edge Family of Filters MaxDiode Laser Diode Clean-up Filters

The MaxDiode filters are ideal for both OEM manufacturers of laser-based fluorescence instrumentation, and laboratory researchers who use diode lasers for fluorescence excitation and other types of spectroscopic applications. The MaxDiode filters’ nearly square passband and exceptional transmission allow maximum signal for faster measurements and better sensitivity. The MaxDiode filters all have extremely steep edges transitioning to very high blocking to filter out the undesired out-of-band noise that is particularly problematic in laser diodes. In addition, MaxDiode filters feature Semrock’s famous “no burn out” hard-coating technology, for lower cost of ownership and proven reliability. Semrock’s initial offerings include MaxDiode filters tailored for the common 635, 440, and 405 nm commercially available diode lasers; other wavelengths planned. The MaxDiode filter family is the much-awaited complement for diode lasers to the popular MaxLine family of narrow laser-line filters – optimized for fixed wavelength gas and solid state lasers.

“Our MaxDiode filters are perfect for spectroscopic applications, like fluorescence excitation, where one needs to measure a weak signal against the background of significant laser noise. They are called ‘clean-up’ filters because they clean up the laser output by stripping it of all the undesired noise and leaving only the desired laser line. The high transmission and ultra-flat passbands are critical for laser diode filters in order to maintain consistent output power as the diode laser wavelength varies with environmental conditions, as the lasers age, and from laser to laser. And MaxDiode filters are made with the same innovative ion-beam-sputtering (IBS) technology Semrock uses to make its other high-performance optical filters, which means our MaxDiode filters contain the same unprecedented reliability, durability, and long-term performance Semrock filters are well-known for,” said Turan Erdogan, CTO of Semrock. “We expect these to be as popular as the MaxLine filters.”
