Semrock/IDEX Health Science

MaxDiode filters are ideal for both volume OEM manufacturers of laser-based fluorescence instrumentation and labratory researchers who use diode laser for fluorescence excitation and other types of spectroscopic applications. Keep the desirable laser light while eliminating the hoise with MaxDiode filters.


  • Highest transmission exceeding 90%, over each diode's possible laser wavelengths
  • Square low ripple passband for total consistency as the laser ages, over temperature, or when replacing a laser
  • Extremely steep edges transitioning to very high blocking to filter out the undesired out-of-band noise
  • "No-burn-out" hard coating technology, for lower cost of ownership and proven reliability.

MaxDiode filters are available from stock for the following laser wavelengths; 375nm, 405nm, 440nm, 470nm, 640nm, 785nm and 975nm. Each filter is housed in a labeled, black-anodised aluminium ring with a diameter of 12.5mm or 25mm and a thickness of 3.5mm. Filters with non-standard sizes are offered and have a one week lead time.
