Typical Measured Spectrum of Semrock LL01-405 Optical Filter
For wavelengths between 320 and 1120 nm, values near or below 3e-7 (Optical Density 6.5) are measurement noise limited.

For wavelengths < 320 nm and > 1120 nm, values near or below 3e-6 (Optical Density 5.5) are measurement noise limited.
