Bandpass Filter Selection Table

Bandwidth Bandwidth is the spectral range over which an optical filter will transmit illumination. Narrow bandwidth filters (<20nm) are typically used in elemental and chemical analysis applications, analytical instrumentation, and laser line clean up. Broad bandwidths (>20nm) are commonly used in imaging applications, including fluorescence microscopy, machine vision, and factory automation. Visit our application note on Optical Filters for more information.
Optical Density Optical Density describes the amount of energy blocked or rejected by a filter. A high optical density value indicates low transmission, and low optical density indicates high transmission. Optical densities of 6 or greater are used for creating high signal-to-noise in applications such as fluorescence microscopy. Optical densities of 3.0 – 4.0 are ideal for laser separation and clean-up, machine vision, and chemical detection, while optical densities of 2.0 or less are ideal for color sorting and separating spectral orders.

OD 6.0 Blocking (<0.0001% Transmission)
OD 6.0 Filters are fabricated utilizing advanced Hard Coating technologies including ion beam sputtering (IBS) and magnetron sputtering, guaranteeing high transmission, deep blocking, and extended lifetimes.
 
 
 
OD 4.0 Blocking (<0.01% Transmission)
OD 4.0 Filters are typically manufactured utilizing high volume Hard Coating technologies, guaranteeing high transmission, deep blocking, extended lifetimes, and generous volume discounts.
 
OD 2.0 Blocking (<1% Transmission)
OD 2.0 Filters are typically manufactured from traditional evaporative coating technologies, or absorptive colored glass, yielding cost effective filters.
