The AB30XX Series of
Long Pass Order Sorting Filters provide blocking of light radiation below the
filter specific transition or cut-on wavelength.
They can be mounted in the AB202 Filter Carrier or in the AB300 Automated Six
Position Filter Wheel. The AB202 Filter Carrier is inserted into the AB200
Filter Mount Assembly. The AB3032, AB3058, AB3066. AB3072, and AB3085 are
long-wave pass, color glass filters and are available in 25.4 mm diameter.
The average high transmittance (TH) of the color glass filters is greater than
90%. The average high transmittance value is the average transmittance of the
filter between the first peak after the cut-on wavelength to the peak before
the cut-off wavelength. The transition interval of the AB30XX Series Filters is
listed in the following table. The transition interval is the distance (nm) from
the cut-on wavelength to the cut-on peak.
The AB3100, AB3190, AB3300, AB3370, AB3720, AB3400, and the AB3840 Order
Sorting Filters are made of semiconductor materials. These long-wave pass
filters are anti-reflection coated for operation from the long-pass wavelength
to at least twice that wavelength.
The average high
transmittance for the AB3100, AB3190, AB3400, and AB3840 filters is greater
than 75%.
These long-pass semiconductor filters are 1 inch (25.4mm) diameter with a
thickness of 0.083" or less (2.1mm). These filters can also be mounted in
the AB201 Filter Carrier or in the AB300 Automated Six Position Filter Wheel.
The blocking average for all of the filters is 0.1% below the passband through
the UV wavelengths.
