54-216 MHz The BPF Series are professional quality, VHF/ FM & UHF bandpass filters. These filters provide extremely high rejection of out of band signals and adjacent channels. The BPF-A utilizes a high-Q, six-stage bandpass filter and two phase cancellation traps to provide excellent rejection of out of band signals. The BPF-U passes a single UHF channel and offers excellent rejection of all channels outside the bandpass of the filter. These filters provide exceptional selectivity with minimum...

The Series 7893D (7894D) waveguide bandpass filter is installed between a TVRO feedhorn and the LNA or LNB to suppress strong out-of-Band interference caused by marine, airport, or military radar systems. Coastal and marine navigational radar frequencies (2.9-3.65 GHz) are just below the TVRO band and frequently wipe-out transponders 1-5 in TVRO's installed near harbors. The airport altimeter band (4.25-4.40 GHz) will affect channels 22-24 at TVRO sites near airports. The series 7893D (7894D) interference...

The Newport TBF-1550-3.0 Tuneable Bandpass Fiber Optic Filter is also called the TBF-1550-1.0. This has a 30nm range around 1550nm. This Bandpass filter is used to adjust the center wavelength around this 1550nm wavelength. The 3mm loose fiber pigtails are unterminated and are about a meter long. The filter features high isolation, low insertion loss, low polarization sensitivity and low back-reflection. Resolution of .05nm is possible by adjusting the tilt angle of an internal filter (located between...

This Baader Planetarium Dark Blue Filter has a bandpass at 435nm and is designed for 1.25" eyepieces. Substrates are plane-parallel polished to within 30 seconds of arc. The Baader Planetarium Dark Blue Filter 70% transmission efficiency and is perfect for revealing lunar details, bright comet tails and planetary work. Can be placed anywhere in the optical path without introducing astigmatism or other defects.

The Original Lumicon Ultra-High Contrast narrow bandpass filter (24nm) isolates just the two doubly-ionized oxygen lines (496 and 501nm lines) and H-Beta line (486nm) emitted by emission and planetary nebulae, while blocking the rest of the overall spectrum of light. The result is extreme contrast between the black background and the delicate photons of nebula light needed for near-photographic views of the Orion, Lagoon, Swan and planetary nebulae, among others.

The Trilithic 5VF55/110-5-75-CC is a tunable bandpass filter. The 5VF55/110-5-75-CC has a range of 55-110MHz, is 5 sections, 75ohms and has BNC connectors.

Band Pass 320nm - 670nm Coated Filter. We have custom designed this filter to pass from 320nm to 670nm with sharp cutoff at 670nm and a slight rise starting at 900nm. This filter has over 11 different layers of vapor deposition coatings over a special UV transparent glass. Using this filter in conjunction with the 330nm filter will result in blocking the slight IR peak of normal UV glass to give you a pure UV image.

The renowned, original Lumicon OIII narrow bandpass filter (11nm) isolates just the two doubly-ionized oxygen lines (496 and 501nm lines) emitted by planetary and emission nebulae, while blocking the rest of the overall spectrum of light. The result is extreme contrast between the black background of space and the delicate photons of OIII light needed for near-photographic views of the Veil, Ring, Dumbbell and Orion nebulae, among other objects.

The Newport TBF-1550-1.0 Tuneable Bandpass Fiber Optic Filter is specifically setup to fine tune a narrow passband around 1550nm. By turning the Newport micrometer actuator, you can adjust the output by +/- 30nm. The typical tuning resolution is 0.05nm and this unit offers very low insertion loss and back-reflection. These have FC/SPC connectors at present, making them Newports option -50, but these can easily be cut off and re-terminated by the experienced user, as they come standard with long pigtails...

View More Images UV, VIS, IR Ranges Circular and Square Sizes Available An optical bandpass filter has a transmission band surrounded by two blocking bands that allow only a portion of the spectrum to pass. These optical bandpass filters have broad spectral bandwidths in either the ultraviolet, visible, or infrared spectrums. The nearly black filters absorb visible radiation. They are perfect for ultraviolet or infrared detection applications. UV filters are often used to selectively transmit the...
