Our MaxDiode filters are ideal for both volume OEM manufacturers of laser-based fluorescence<br />
instrumentation and laboratory researchers who use diode lasers for fluorescence excitation and<br />
other types of spectroscopic applications. Keep the desirable laser light while eliminating the<br />
noise with MaxDiode filters.<br />
Square low-ripple passband for total consistency as your laser ages, over<br />
temperatures, or when installing a replacement laser<br />
Highest transmission, exceeding 90% over each diode’s possible laser wavelengths<br />
Extremely steep edges transitioning to very high blocking to successfully filter<br />
undesired out-of-band noise<br />
For narrow-line lasers, use our MaxLine ® laser-line filters (see page 98.<br />

Performance for Non-collimated Light<br />
The high-transmission portion of the long-wavelength edge and the low-transmission portion<br />
of the short-wavelength edge exhibit a small “blue shift” (shift toward shorter wavelengths).<br />
Even for cone half angles as large as 15° at normal incidence, the blue shift is only several nm.<br />
All other mechanical specifications are the same as MaxLine ® specifications on page 99.<br />
