DICHROIC FILTER : SHORT WAVE PASS (SWP) & LONG WAVE PASS (LWP)
Dichroic Filter coatings are designed to transmit one spectral region (passband) and reflectanother (rejection band).
The filter is a Short Wave Pass if the passband is to the left of the transition slope, and a Long Wave Pass if the passband is to the right of the slope.
TO ORDER : The codes listed above are for ordering coating service for customer supplied substrates only.
Ex: 1) SWP; 4.0 μm; 0。: SWP 400 0 2) LWP; 10.0 μm; 45。; unpol.: LWP A06 4 U
These and other coatings are available from stock on a variety of substrates. Other wavelengths and angles of incidence can be provided upon request. Please contact our sales department for assistance.
