Digital Bandpass Filter

digital bandpass filter

    bandpass filter
  • A band-pass filter is a device that passes frequencies within a certain range and rejects (attenuates) frequencies outside that range. An example of an analogue electronic band-pass filter is an RLC circuit (a resistor–inductor–capacitor circuit).

  • A filter that attenuates signals both below and above the desired passband.

  • An electric circuit designed to pass only middle frequencies.

  • displaying numbers rather than scale positions; "digital clock"; "digital readout"

  • Involving or relating to the use of computer technology

  • of a circuit or device that represents magnitudes in digits; "digital computer"

  • relating to or performed with the fingers; "digital examination"

  • Relating to or using signals or information represented by discrete values (digits) of a physical quantity, such as voltage or magnetic polarization, to represent arithmetic numbers or approximations to numbers from a continuum or logical expressions and variables

  • (of a clock or watch) Showing the time by means of displayed digits rather than hands or a pointer

digital bandpass filter - Spectral filtering

Spectral filtering of light-emitting diodes for fluorescence detection [An article from: Analytica Chimica Acta]

Spectral filtering of light-emitting diodes for fluorescence detection [An article from: Analytica Chimica Acta]

This digital document is a journal article from Analytica Chimica Acta, published by Elsevier in . The article is delivered in HTML format and is available in your Media Library immediately after purchase. You can view it with any web browser.

The use of light-emitting diodes (LEDs) for fluorescence detection has recently gained much interest. The broad wavelength emission of LEDs requires spectral filtering that is not necessary when using a laser. For instance, filtering the LED light using a bandpass filter improves the signal-to-background ratio for riboflavin by a factor of 70. The bandwidth of the necessary bandpass filters affects both the signal and the background in these measurements. Fluorescence signal can be maximized with wider-bandpass high-transmittance filters. Background is governed by scattering of the LED emission light transmitted by two bandpass filters. When there is large crosstalk between the filters, the LED intensity is linearly related to the background. By estimating and optimizing the crosstalk between excitation and emission filters with a method presented here, the signal-to-background can be optimized. Bandpass filters should be selected with sharp on-off transition, strong blocking outside their transmitting region and the widest bandwidth with minimal crosstalk. Using optimized spectral filtering and capillary electrophoresis analysis, LODs of 50, 3 and 20nM are obtained for riboflavin, fluorescein and eosin Y, respectively. These results are superior to those reported in the literature for 5mW LEDs.

Test digitalnog foto-aparata modifikovanog na prosirenu registraciju spektra i UV/IC delove. Ovo je preliminarni test. Predstoje probni snimci sa filterima od 330 do 1000nm, za sta su mi potrebni suncani dani (i slobodno vreme ;-))...
This is a quick test-shot taken with a digital camera modified for "full spectrum" imaging. When I get more sunny days (and free time ;-)), I`ll make some more shots using filters from 330 to 1000nm bandpass. ("Vidljivi spektar" refers to visible spectrum, and "Posle obrade" means processed image.)

Photo taken with a Yashica EZ Digital F521 that i have removed the lens from and replaced it with a lens with an 85 degree FOV and no infrared filter. Macro mode cleary still works and you can get a lot closer. My plan is to get an infrared filter to filter out the IR light, you can see under fluro light the colour is pretty good. I also want to try cutting up some exposed 35mm and make a bandpass filter and take some real infrared shots.

Celestron 94124 2-Inch UHC/LPR Telescope Filter

Light Pollution Reduction (LPR) Filters are designed to selectively reduce the transmission of certain wavelengths of light, specifically those produced by artificial light. This includes mercury vapor, and both high and low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. sky glow). The new ultra high contrast (UHC) LPR filter has improved contrast over the typical broadband filters. Sky background is darker, and contrast of emission nebulae are noticeably improved. The advanced technology coatings enable the filter to achieve an outstanding transmission of over 97% across the entire bandpass, with total blockage of prominent light pollution lines. The perfect filter for viewing nebula from light polluted skies, or for boosting the contrast of nebula from dark sky sites. In addition to it's optimum spectral and optical characteristics, the UHC/LPR filter offers important features that set it apart and result in the highest quality celestial views:

  • A very large and robust external filter. Typically a very large canister outside the aquarium that can be filled with filter media. Water is sucked from the aquarium, forced through the filter media, and then returned to the aquarium.

  • Aquarium filters are critical components of both freshwater and marine aquaria.Leibel WS (1993) A fishkeepers guide to South American cichlids. Tetra Press. Belgium pg 12-14. Aquarium filters remove physical and soluble chemical waste products from aquaria, simplifying maintenance.

  • This filter consists of a canister external to the aquarium which is filled with various media, mechanical or chemical. Hoses run to and from the canister, and an attached pump forces water through the canister.

  • A fast-flowing and turbulent part of the course of a river

  • A rapid is a section of a river where the river bed has a relatively steep gradient causing an increase in water velocity and turbulence. A rapid is a hydrological feature between a run (a smoothly flowing part of a stream) and a cascade.

  • The Real-Time Automated Personnel Identification System (RAPIDS) is a United States Department of Defense (DoD) system used to issue the definitive credential within DoD.
