Andover Corporation Datasheets for Long Pass Filters and Short Pass Filters

Long pass filters transmit a wide spectral band of long wavelength radiation while blocking short wavelength radiation. Short pass filters transmit a wide spectral band of short wavelength radiation and block long wave radiation.

Product Name Notes
Andover can design and fabricate custom IR long pass filters to suit your particular requirements. Every phase of the process is performed in-house, including thin-film coating design, mechanical design, substrate...
Long wave pass filters are often used for order sorting, they isolate broad regions of the spectrum, simultaneously providing high transmission of desired energy, and deep rejection of unwanted energy.
Often referred to as long wave pass (LWP) and short wave pass (SWP) filters, these sharp-cut edge filters are distinguished by their high rate of transition between their region of...
Our steep-edge long pass filters employ magnetron sputtered hard oxide coatings to yield deep rejection and a sharp transition to very high transmission. The coatings are deposited on precision polished...
Long pass type filter glasses are useful for order sorting applications. They block the shorter wavelengths while transmitting the longer wavelengths. As with all of Andover's filter glasses, custom sizes...
