| Andover offers a high-transmittance variant of its standard bandpass filter selection. By tailoring the blocking range to match the detector, we can provide the maximum possible throughput while maintaining good... | |
| DICHROIC FILTER GENERAL SPECIFICATIONS Far more durable than dyed plastic or gel-coated types, dichroic glass filters have a hard dielectric film created by thin layers of metallic oxides. These color... | |
| Dichroic filters (color separation filters) are used in a variety of applications where it is necessary to isolate certain regions of the visible spectrum. A few of the more common... | |
| Hot Mirrors perform as their name states: they reflect the heat and transmit the visible light. All of the coatings are classified as hard, first-surface dielectric, and will meet or... | |
| In order to make it simple for customers to custom-tailor an optical bandpass filter for their application, Andover offers a line of Semi-Custom bandpass filters. Their construction is similar... | |
| 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... | |
| These filters are very similar to the Hot Mirrors with the exception of their longer IR blocking range. This extended blocking range is achieved by a combination of reflection from... | |
| THREADED FILTER RINGS In addition to our standard rings, Andover offers a variety of threaded ring mounts. Standard sizes and thread pitches enable the user to attach the filter securely... | |
| UV - VIS - NIR Andover maintains a stock of high-quality surplus optical bandpass filters. These are primarily overruns of custom production lots, and exhibit the same high level of... | |
| With their ability to minimize back-reflections and scattered light, absorptive neutral density (ND) filters are ideal for calibration. In contrast to the metallic type, absorption-type filters achieve their optical density... | |
| Heat-absorbing filter glasses transmit a broad band of energy while blocking the near IR wavelengths. As with all of Andover's filter glasses, custom sizes are available upon request, and can... | |
| J-band 1100nm to 1400nm H-band 1500nm to 1800nm K-band 2000nm to 2400nm L-band 3000nm to 4000nm M-band 4600nm to 5000nm N-band 7500nm to 14500nm Near-Infrared, Mid-Wave Infrared, and Far-Infrared Astronomy... | |
| 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... | |
| Optical bandpass filters are designed to transmit a well-defined band of energy in the electromagnetic spectrum. Andover offers one of the most extensive listings of standard "off-the-shelf" optical filters in... | |
| Our first-surface, hard-coat broadband filters employ magnetron sputtered, hard-oxide coatings deposited on Borosilicate Glass and do not utilize any absorbing filter glasses, making them suitable for high-temperature applications. They provide... |
